Unconventional methods of material cutting
Kulenda, Martin ; Mrňa, Libor (referee) ; Podaný, Kamil (advisor)
The present bachelor thesis summarizes the findings of unconventional methods of materials cutting. The thesis is only concerned with the most common and most appropriate methods used in practice. The described methods include cutting by laser, plasma, water jet, electron beam and ultrasound. For each of these methods, the principle of current technologies and technological equipment used for materials cutting in industrial practice is described. This thesis compares the individual methods in terms of their advantages and disadvantages when cutting different types of materials and also the appropriateness of the use of such methods in small or large series production.

Development of Imaging Methods and its Importance to Biomechanics
Sedláček, Tomáš ; Houfek, Martin (referee) ; Florian, Zdeněk (advisor)
The main objective of this bachelor thesis is to collect all available literature, from which can reader obtain basic knowledge of imaging methods. The methods are divided by its origin into four categories: x-rays, magnetic resonance, ultrasound and nuclear medicine. Each of them is described from the historical, physics and technological view. At the end the importance of each method to medicine and biomechanics is summarized.

Diagnostic methods for the evaluation of the state of timber structures
Štěpánek, Jakub ; Stehlík, Michal (referee) ; Heřmánková, Věra (advisor)
This thesis is dealing with diagnostic methods and methodics of research of timber constructions. Theoretical part is focusing on timber as material for constructions, it's defects, physical and mechanical properties, overview of diagnostic methods and their appropriateness of use. In practical part I am describing performed diagnosis of element of timber construction with focusing on comparing transfer speed of the ultrasonic waves to selected mechanical and physical properties.

Methods for the survey reinforced concrete bridges
Ehrenberger, Ondřej ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
Policies and types of diagnostic examination of a bridge. The theoretical section contains review diagnostic methods for a steel concrete frameworks. In a practical section there is made a examination of a bridge object over a river Moravia and a suggestion of the examination according to the detected defects. In the experimental section we are discovering, with a help of georadar, a location of reinforcement of a monolithic wall and board.

Application of non-destructive methods determining the quality of glued wood bondlines
Dvořáková, Martina ; Brožovský, Jiří (referee) ; Vaněrek, Jan (advisor)
The presented bachelor thesis is focused on the evaluation of timber elements by using non-destructive methods which are intended for the evaluation of glue lines. The main part of the work is focused on summarizing and the detailed description of selected non-destructive methods which can be used for glue line evaluation. There is also carried out the researche of selected scientific articles describing the application of non-destructive methods with regard to the evaluation of timber elements.

Study of the development, trends and innovations in shotcrete technology
Záruba, Jiří ; Hela, Vlastimil (referee) ; Hubáček, Adam (advisor)
The Bachelor thesis is focused on the study of development, trends and innovations in shotcrete technology. The main target of this thesis is to summarize new procedures in shotcrete technology. Secondary targets include a description of basic properties of sprayed concrete, introducing new trends and technology in recent years. The next sub-goal is to propose experiment that will try new ways of testing shotcrete. Based on these secondary targets is possible to evaluate the current situation in shotcrete technology and fulfil the main objective of this thesis.

The role of radiology in children hip screening in Pelhřimov Hospital, c. o.
CHADIMOVÁ, Jana
The topic of this thesis is to compare the use of imaging methods in children hip screening and to find out the presence of developmental dysplasia of the hip (DDH) in Pelhřimov Hospital. DDH is the most common musculoskeletal developmental defect which affects approximately 5% of newborns. It includes an impaired development of acetabulum, femoral head, poor centering into the acetabulum or disproportionate extent of joint movement. DDH is being formed by interaction of genetic factors and external causes. If DDH occurs in the family, the risk neonate increases significantly. The most serious stage of this defect is hip dislocation, but we often meet a lighter form of this defect, which is called shallow acetabulum. The Czech Republic established a system of consecutive check-ups of neonates and infants. It was created on the base of Methodological Sheet of the Ministry of Health from 1996. These examinations are carried out in three stages. During these examinations, ultrasound plays a very important role. The most common method, also used in Pelhřimov Hospital, is the method of Austrian professor Graf. This method evaluates findings and classifies them into groups. After the first year of age, when ossification of structures is nearly completed, the findings cannot be evaluated by this method. X-ray examination is applied in case of diagnostic uncertainties - especially when planning subsequent treatment in children with DDH diagnosis. Imaging methods are applied to determine anatomical reposition obstacles after an unsuccessful primary reposition. We can use ultrasound, magnetic resonance, but we prefer arthrography. Arthrography is more invasive method, but unlike the others, it has got an important advantage: it can also be a therapeutic method. The theoretical part deals with anatomy, development and growth of the hip joint. I also present etiology and history of this developmental defect. The following part deals with a description of the system of clinical check-ups and diagnostics of DDH. Another part of the theoretical work is devoted to individual imaging modalities - ultrasound, X-ray, magnetic resonance and arthrography. Imaging modalities are a very specific part of radiodiagnostic. Paediatric patients are not small adults, their imaging should be restricted to a minimum and it has got its own specifics. The examination must be performed quickly and accurately, in order not to have to be repeated. Options of therapy varies according to the severity of the hip joint. A small damage of the hip joint is solved by a conservative way using various abduction tools like abduction package, Frejk duvet or Pavlík calipers. More serious cases need to be solved by hospitalization, using distraction therapy or surgery. The aim of this work was to analyze the number of paediatric patients, to find out what kind of imaging methods were indicated and performed and to compare the presence of congenital defect of the hip according to sex within Pelhřimov Hospital. The hypothesis of this thesis was formulated as follows: In paediatric hip screening examination in Pelhřimov Hospital presence of congenital defect of the hip is higher in girls than in boys. The purpose of this thesis was to create a comprehensive text dealing with the use of imaging methods in detecting developmental defects of paediatric hip. The theoretical part of this work may serve as information material for professionals and the results can be used as statistical material.

Radiographer role in non-vascular intervention procedures and their frequency at Imaging clinic of Faculty Hospital Motol in years 2008 - 2013.
BOROVCOVÁ, Veronika
This bachelor thesis focuses on non-vascular interventions, which are carried out at the Imaging clinic of Faculty Hospital Motol. The area of interest was fixed to the adult part of this clinic. The most frequently performed interventions were described and for aech of these examinations was depicted the role of radiographer (patient preparation, sterila table and instrumentation preparation) and it´s operating procedures. The other part of the thesis pays atention to statistical analysis of the frequency of individual most often led examinations. The statistical overview was done by using tables but also graphs. The examinations are devided according to their modalities based on where they were ran. This division was left for statistical part, as well. The period of time, which was trailed in this thesis makes 6 years, since 2008 to 2013. The obtained data displays the individual frequency of interventions and covers complete overview in mentioned issue.
