The classical and quantum applications of X-ray imaging methods
FIKSLOVÁ, Anežka
The topic of the bachelor's thesis is responding to the finding that there is no simple educational text which is dealing with the topic of X-ray imaging methods that is unifying applications of classical and quantum physic and X-ray theory structure currently. The purpose of this bachelor's thesis is to create a theoretical base that is summarizing knowledge of classical and quantum physic applications of X-ray imaging methods based on the application of the theory of curricular process. There are no studying materials in the Czech Republic suitable for radiological assistants which are unifying substantial basics of classical and quantum physic with basics of imaging in the radiodiagnostics. There were set following goals on the basis of the analysis of the current situation: G1 To describe applications of classical and quantum X-ray imaging methods and assess whether there is some preference for classical aspects of those imaging methods. G2 To assemble an educational text and test. There should be put emphasis on the application of classical X-ray imaging methods. The results of the test are going to be statistically processed and the knowledge of the students is going to be judged. Based on the goals, three following explanatory hypotheses were made: H1 The application of classical X-ray imaging methods can be described by comparison of the structure of the barking X-ray radiation and the structure of the classical physic. H2 The application of quantum X-ray imaging methods can be described by comparison of the structure of quantum physic and the structure of characteristic X-ray radiation. H3 The knowledge of respondents is going to follow a curve of a normal distribution. As the main theory was chosen the theory of curricular process which should ensure transmission of knowledge from the scientific system to the educational system. By the description of X-ray imaging methods from the perspective of its own classical and quantum basis was filled the first goal. On the basis of comparative analysis were accepted the first and the second theses. By application theory of curricular process was created educational text of some selected knowledge about X-ray radiation. On the basis of this text, the test for respondents was made. By using descriptive and mathematical statistics was made statistical research and its results are mentioned in the application part. That can be considered as filling the second goal of this thesis. On the basis of nonparametric testing was found that the knowledge of respondents is following Gaussian distribution. That is why the suitability of the educational text was confirmed and the third thesis was filled. The results of this thesis show that this educational text can be used for the education of radiological assistants students.

Sources and interactions of ionizing radiation in nuclear medicine for radiology assistants
PRCHALOVÁ, Anna
Currently, there is not available educational text on the subject of sources and interactions of ionizing radiation in nuclear medicine that would be adequate to the physics knowledge of students in the field of Radiologic Assistant and other related disciplines. In this thesis, there was an attempt to create a comprehensive educational text on the basis of the application of curricular process theory, which discusses the radionuclide diagnostics and therapy for radiologic assistants and other related disciplines on the basis of an analysis of the current state of scientific knowledge in the examined area. The chosen topic is described in the theoretical part of this thesis and it was adjusted for the selected group of respondents in a form of the educational text. The intelligibility of educational text was verified by the statistic research using a questionnaire survey that respects the educational text and it was presented to the students in the field of Radiological Assistant.

Physics problems for radiology assistants
KOVÁŘ, Jan
The thesis was examining an opportunity to apply the curriculum process theorem in the matter of general and radiology physics and their problems' expression. The first objective is to create an educational text which would elucidate an indispensable theory for radiology assistant. The educational text is to involve problem expressions of needful physical fields. The second objective was to implement the curriculum process as a quiz and so to evaluate the familiarity among the professionals in the field. Furthermore, three hypotheses were formed. The first hypothesis presumed it is possible by applying the curriculum process to delimit the collection of physics problems that will be tailored to the needs and facilities of radiology assistants. The second hypothesis was divided into two subparts: A) By comparison of a physics structure and compounds of a radiology assistant profile it is possible to process a collection of problems dedicated to general physics. B) By comparison of a physics structure and compounds of a radiology assistant profile it is possible to process the collection of problems dedicated to radiology physics. The third formed hypothesis presumed the familiarity among responders regarding the field will resemble of normal distribution. By comparing the conceptual curriculum of physics and radiology, an educational text was created, which contained exemplary statements of general and radiological physics in relation to the components of the profile of the radiological assistant. By creating the text and defining example statements, the first goal of the work was fulfilled, and the first two hypotheses were accepted. Another application of the curricular process was to compile a test, the questions of which were based on the content of the educational text. Descriptive and mathematical statistics were used to appraise the research observing the test results. The outcome of the research acknowledged the third hypothesis. The second objective was reached by the test implementation. As a certain standardisation the second, previously used test was handed to the responders concomitantly to the first test. Via a parametric test the link between both tests results was confirmed. Following correlation analysis established the strong positive correlation. The results of the bachelor's thesis show that the created educational text together with a set of example statements can be effectively used to prepare students for the profession of radiological assistant.

Elementary mathematics of imaging methods for radiology assistants
JELÍNKOVÁ, Barbora
The topic of the bachelor's thesis responded to the finding that there is currently no suitable educational text containing mathematical foundations for the education of radiological assistants and other related fields. The bachelor thesis contains selected areas of mathematics that are necessary to know to understand the physical foundations of imaging methods. The formulation of these areas is appropriate to the needs of future graduates of these fields of study. The goals of the bachelor thesis were the following: G1 Creation of an educational text and examples containing elementary mathematics that are essential to fully understand physical principles of imaging methods. G2 Compilation of a test that will be used to verify the knowledge of mathematics of radiological assistance field students and its graduates, followed by a statistical expression of knowledge level. Based on the goals, the following hypotheses were made: H1 By application of a curricular process a structure of elementary mathematics of imaging methods for radiological assistants can be described. H2a By comparing mathematical structures with components of a radiological assistant´s profile, individual structural levels of elementary mathematics for radiological assistants can be described. H2b According to needs and abilities of radiological assistants, examples of functions, differentiation, integration, and vectors can be chosen. H3 Knowledge of respondents in radiology mathematics will be distributed close to a normal distribution. With regard to the curricular process, a teaching text was compiled together with example illustrations. This step led to the fulfillment of goal G1. Then, a single-choice test of 20 questions was compiled to determine the level of mathematics knowledge across the field of radiological assistance. This step led to the achievement of goal G2. This test was subsequently extended using an online form among radiological assistants and students in this field. Given the above objectives, hypotheses H1, H2a and H2b could be confirmed. The test results were statistically expressed in the practical part of the bachelor thesis. It was confirmed that the empirical distribution of test responses is close to the normal distribution. Hypothesis H3 was also confirmed by this step. The benefits of the bachelor's thesis can be seen in the practical level (construction of an educational text verified by a test survey) and in the theoretical level (verification of the application of the theory of the curricular process).

Technical bases of thermography for radiologists.
SOSNA, Filip
The bachelor thesis solved the technical fundamentals of thermography using the curriculum process. The bachelor thesis has investigated the problem in the following way: Goal 1: Perform a system analysis of the technical bases of thermography and adapt the results to the capabilities of radiological assistants - Goal 1 was accomplished by performing a system analysis of the structural levels of the technical bases of thermography. Goal 2: Perform a comparative analysis of the technical bases of thermography abroad and in the Czech Republic - Goal 2 was met by comparison between America, Asia and Europe and the Czech Republic (with an unsuccessful result for the Czech Republic). Goal 3: To transform the results of system analysis, adapted to the needs and possibilities of future radiological assistants, into educational form - goal 3 was fulfilled on the basis of selected educational theory and its application. Goal 4: Choosing a suitable educational theory to convey knowledge about the technical bases of thermography to radiological assistants - Goal 4 was accomplished by selecting the theory of the curricular process. Hypothesis H1: Educational form of the technical basics of thermography for the examined group of recipients can be created by applying the theory of curricular process - Successful implication of individual variant forms of the curriculum on the research field of technical basics of thermography enabled the hypothesis H1. Hypothesis H2: Knowledge of the recipients of education in the field of technical basics of thermography will have a Gaussian distribution close to the implemented distribution curriculum - Successful application of selected types of theoretical distributions (exponential distribution, normal distribution) to the result of the educational test. The theoretical benefits of the thesis include the design of structural levels of the system of technical basics of thermography. The practical benefits of this thesis include, for example, creating an educational text and a test for the technical basics of thermography. Based on the achieved results, it is also possible to propose follow-up work - eg exploring the possibilities of increasing the use of thermographic imaging methods in the Czech Republic.

Physical bases of thermography for radiotherapists
LÁVIČKA, Šimon
There is currently no educational material for radiological assistants and students in this field to discuss the physical foundations of thermography. In particular, material which is appropriate to the presumed physical and mathematical knowledge required for the field of Radiologic Assistant and other related disciplines. Especially due to the fact that part of the scientific community sees in thermography a promising method for mammologii, rheumatology, orthopedics, angiology and dentistry. This motivation led to the elaboration of this bachelor thesis which set out these following goals: The selection of theory of knowledge transfer to the level of "Radiological Asssistant" and other related fields. The creation of an educational text that respects the chosen theory and reflects the blackbody radiation laws. The monitoring of current state of thermography knowledge in the addressees. There were two hypotheses formulated on the basis of an analysis of the current state and the setting of objectives: The application of theory to the curriculum process can create important components of a project curriculum for a given group of learners. The knowledge of the learners will have a theoretical distribution of the near- normal distribution in the area of physical fundamentals of thermography. As a convenient theory for transferring knowledge from science to the educational sphere has been proved to be the theory of the curricular process. Its applicability was accepted by the international scientific community as well see the impacted publication (Záškodný, 2012). Firstly, it was necessary to remind a generally known relationship of infrared radiation to thermography and than analyze the discovered theoretical physical backgrounds up to date, the most important for thermography also in relation to the radiation of the blackbody. There are also shown and described subsequent physical laws: Stefan-Boltzmann law, Wien displacement law, Rayleigh-Jeansons law and Planck´s radiation law, whereby it is especially necessary to emphasize the relationship of these laws to blackbody radiation whose temperature is between 0 K or -273,15 through the explanation of the emissivity parameter, which is a dimensionless quantity determining the heat emission capability. Its value must be entered in the thermal camera. Subsequently, a knowledge test was created on eighteen questions with a selection of four options, where only one was correct. Twenty-five radiological assistants active in their field at the age of twenty-three to fifty-three, with a length of practice from half a year to thirty-one years, were addressed. The methods of descriptive and mathematical statistics were used in the quantification of the addressees´ knowledge. All twenty-five tests were processed this way. Performing nonparametric testing of the empirical distribution of the scores obtained from these tests revealed that the second of the hypotheses set was not confirmed. The knowledge of the addressees was higher than the hypothetical assumption.

The classic and quantum dimension of X-ray diagnostics for radiology assistants
BEJTIC, Martin
These days there is no educational text for the issue freely available that would be adequate for the students of the course Radiology assistant and for related fields. The work set the following aims: 1. To choose a theory of transmission of the knowledge to the level of the fields mentioned. 2. To create an educational text so that the theory would be respected. 3. To verify the educational text experimentally from the point of view of the students'possibilities. 4. To apply selected statistical methods. Based on the present analysis of the issue and set aims the following hypotheses were formulated: 1. The educational text for radiology assistants can be created through the application of curricular process. 2. The knowledge of the students acquiered through the developed educational system will be divided in a similar way as it is divided normally. The aims mentioned above were accomplished thanks to use of all the aspects of the curricular process. Based on this process it was first necessary to analyse the current scientific system of classical and quantum physics. Adjusted physical knowledge were written up into an adequate educational text for radiology assistants. The hypothesis that an educational text for radiology assistants can be created through the application of the curricural process was verified. The text was provided electronically to the students of South Bohemian University and to radiology assistants. A test of 15 questions was created to verify the knowledge acquired by students. The educational test was also provided electronically. The results were then processed statistically. It was made use of methods of descriptive statistics, but also of nonparametrical testing of hypotheses. It was found out that the knowledge of the students can be described with Gaussian division based on the nonparametrical testing. Thanks to this the adequacy of the text and the second hypothesis that the knowledge of the students acquired through the developed educational system would be divided in a similar way as it is divided normally were verified.

The physic principles of relativistic linear accelerator for radiological assistent
VODVÁŘKA, Marek
As the selected theory of transfer of knowledge from the scientific radiological physics (in the sphere of physical bases of relativistic linear accelerator) to students of radiological branches the theory of curricular process was used. This theory was formulated in the world by M. Pasche, T. G. Gardner, M. Certon, M. Gayl, in the Czech and Slovak Republics by J. Průcha, J. Brockmeyerová, P.Tarábek, P. Záškodný. On the base of the curriculum process theory, in the sphere of radiological physics curriculum process can be defined as a sequence of transformations T1-T5 variant forms of curriculum: "Conceptual curriculum" as a communicable scientific system of radiological physics (first variant form of curriculum as transformation T1 output from a scientific system to a communicable scientific system). "Intended curriculum" as an educational system of radiological physics (second variant form of curriculum as transformation T2 output from a communicable scientific system to an educational system). "Project curriculum" as an instructional project of radiological physics (third variant form of curriculum as transformation T3 output from an educational system to a teaching project). "Implemented curriculum-1" as the preparedness of educator to education inradiological physics (fourth variant form of curriculum as the first transformation T4 output from an educational project to implementation of teaching). "Implemented curriculum-2" as the results of education in radiological physics (fifth variant form of curriculum as the second transformation T4 output from aneducational project to implementation of teaching). "Attained curriculum" as applicable results of education in radiological physics (sixth variant form of curriculum transformation T5 output from implementation of teaching to application of the results of teaching). In this thesis, in the sphere of physical bases of relativistic linear accelerator the transformation between the intended curriculum, project curriculum, implemented curriculum-1 and implemented curriculum-2 were used. These transformations were carried out by binds between educating text, experimental teaching, preparation for experimental teaching and placing of educational test to students of radiological branches to find out the results of experimental teaching in the sphere of physical bases of relativistic linear accelerator. In order to prove the hypotheses of the bachelor thesis, methods of mathematical statistics apart from methods of descriptive statistics were used: Nonparametric tests and two sample t-test. Nonparametric test was used to test the normality of knowledge acquired by experimental teaching. Two-sample t-test was used to compare the knowledge from the sphere of physical bases of relativistic linear accelerator in students of full-time and part-time study programme. The bachelor thesis was based on the verification of two hypotheses: a) an adequate educational text in the sphere of physical bases of relativistic linear accelerator can be created by application of curriculum process b) students´ knowledge in the sphere of physical bases of relativistic linear accelerator acquired on the base of worked out educational text will have normal distribution. Both of these hypotheses were confirmed by statistical processing of the results which were obtained by experimental teaching and by placing of educational test to students. Partial hypothesis was also confirmed that knowledge between full-time students and part-time students will not be statistically different on the level of statistical significance 0.05.

The theory of nuclear physics for radiological assistants
ŠIMKOVÁ, Kamila
Currently there is not freely available any simple educational text on the subject of nuclear physics foundations, which would be adequate to the knowledge of students in the field of Radiology Assistant and other related fields. Study materials that are commonly used are mere transcripts of a scientific knowledge which needs to be adjusted by the presenter in order to be correctly understood by students within the stipulated time. The need for defining an educational version of a nuclear physics for Radiology Assistant resulted in preparation and submission of this thesis. During the process several objectives emerged: - create awaited, projected and implemented curriculum (create comprehensible educational text and verify its adequacy) on the subject of nuclear physics foundations for Radiology Assistant - verify the suitability of the project curriculum using the experimental teaching followed by subsequent verification with questionnaire survey - apply methods of descriptive statistics and mathematical statistics This thesis was based on two hypotheses verification. 1st hypothesis: By application of curricular process theory and developing appropriate educational text can be processed theoretical foundations of nuclear physics for Radiology Assistants. 2nd hypothesis: Knowledge of Radiology Assistants in the field of theoretical foundations of nuclear physics obtained from drawn up educational text will have distribution near to the normal distribution. Contribution of the thesis is the elaborated educational text and test that can be used for teaching theoretical foundations of nuclear physics. After evaluation of individual questions in the test, can be recommended to focus on students' knowledge in those areas where lower scores were achieved.
