Imaging of the gastrointestinal tract - ERCP
HROCHOVÁ, Simona
The bachelor thesis on GIT imaging methods with focus on ERCP deals with diagnostic and therapeutic methods and provides an overview of the individual imaging methods used in diagnostics and therapy. In the practical part, the thesis focuses on the ERCP diagnostic and therapeutic method. Knowledge of anatomy is indispensable for the orientation in this field and for the quality work of radiological assistants and physicians, and therefore the introduction is dedicated to GIT anatomy. Diagnostic procedures, including imaging methods, are described in each individual anatomical area, and the most common diseases affecting the indicated GIT area are listed. The second half of the theoretical part describes the diagnostic and therapeutic imaging methods of the digestive tract with respect to the anatomical area in which the examination is carried out, which fall under the X-ray unit and are performed by radiological assistants and doctors. The practical part is focused on the diagnostic and therapeutic method ERCP and its use at the RTG unit at Thomayerova hospital in the years 2014-18. The work covers the entire course of the examination from the preparation of the patient to the therapeutic procedures. A set of patients is used in terms of the frequency of the examinations carried out in 2014-18. In the individual years, patients are further broken down and analysed based on the decade of birth and gender. The data sets obtained are processed into clear graphs and the use of the method today is evaluated based on the proportion of patients undergoing the examination in the individual years using the date of birth and gender criteria. Specialized books and articles as well as verified internet sources were used to write this bachelor thesis. The results of my work give answers to the research question about the preferences of using the ERCP examination. They reflect the ongoing trend in the use of ERCP in diagnostics and especially in therapy due to the undeniable advantage of the use of therapeutic interventions immediately during the diagnostic examination. The aim of the thesis is to create a general overview and description of the individual methods of GIT examination according to the individual anatomical area with focus and a more detailed description of the ERCP method. An analysis of the data set obtained at the Thomayer Hospital's RTG unit was carried out.

Noninvasive image analysis of hallux valgus
Setínková, Jana ; Lopot, František (advisor) ; Kubový, Petr (referee)
6 Abstract Title: Noninvasive image analysis of hallux valgus. Objectives: Propose a simple, cheap, fast and non-invasive method for diagnostics and monitoring the effect of therapy of hallux valgus deformity. Methods: Evaluation the parameters in X-ray and photography which were taken before and after therapy of hallux valgus. I measured angles on foot in programme AutoCAD and confront the correlation of angles in X-ray and photography. I also looked for an angle similar to the hallux valgus angle. Results: The method of photography can be effective in physiotherapeutic practise. This diploma is a case study, therefore we cannot consider the results implicitly significant. Keywords: Hallux valgus angle, X - ray, photography, HV I angle, HV II angle

Reliability of LED Panels Solder Joints
Šimon, Vojtěch ; Špinka, Jiří (referee) ; Starý, Jiří (advisor)
Thesis is focused on the effect of heating factor on quality of solder joints. In theoretical part is solved reflow soldering technology, problematice of solder paste choice or criteria of soldering profile setting. The practical part is dedicated to demonstrating the impact of heating factor on solder joint quality. There are used X-Ray analysis, microsections and electron microscopy. In the final part of this thesis are summarized knowledge from theoretical part and experimental obtained results to defend of next steps in diploma thesis.

Emerging Trends in Dendrochronology
Horáček, Tomáš ; Neuwirthová, Ludmila (referee) ; Mikulka, Jan (advisor)
Tato práce se zabývá popisem současných a experimentálních metod odběru vzorků pomocí presslerova nebozezu, výřezů z kmene, fotografie, rentgenu, počítačové tomografie a magnetické rezonance na poli dendrochronologického výzkumu. V práci jsou rozebírány destruktivní a nedesktruktivní metody odběru vzorků. Je také kladen důraz na původ vzorků: zdali je možno využít destruktivní metody nebo zdali je to nemožné jako v případě vzácných archeologických objektů. Dále popisuje standardní optometrickou metody a další experimentální metody fungujicí na principu kontranstního zpracování obrazu za účelem rozeznání letokruhů. V práci jsou také popsány různé druhy metod softwarového zpracovnání kde jako vstup slouží buď série dat nebo obraz letokruhů. Další rozdíly tvoří vymezené spektrum uvedených prací, některé práce se zaměřují na zpracování obrazu od píky tedy od pořízené fotografie až po hotové datovaní, některé však zajímá pouze úzký sektor dendrochronologie jako jsou například vady či špatně rozeznatelné letokruhy.

Lead-Free Voids Cause Mechanisms and Influence on Reliability
Šimon, Vojtěch ; Špinka, Jiří (referee) ; Starý, Jiří (advisor)
The aim of this work is to analyze reliability of lead-free solder join, in particular the voids generated during the soldering process. The main target of the theoretical part of the work is to isolate basic mechanisms of formation of the voids and optimize the soldering process. The practical part of the paper is based on monitoring the count and size of the voids in a solder join. An X-Ray tomograph has been chosen as a non-destructive method of detection. The statistical part of this work compares conventional soldering of the entire board with local soldering by IR radiation.

Locating welds defects on cranes.
Zíka, Luboš ; Hála, Michal (referee) ; Kubíček, Jaroslav (advisor)
The diploma thesis deals with the problematics of weld defects of cranes localisation and check. The aim is to analyse non-destructive methods, monitor the occurence of defects and their form and also to suggest the procedure of correction. The work is divided into a theoretical and practical part. In the theoretical part, there is an analysis of individual methods of non-destructive testing that are used for weld check on a particular girder. There is also an analysis of welding technologies used when making a crane girder. The practical part deals with evaluation of weld defects using two methods of non-destructive testing. Furthermore, statistics of defects is realised. In conclusion, the statistics outcome is resumed and evaluated.

Design of metal detector and X-ray luggage scanner
Fridrichová, Eva ; Paliatka, Peter (referee) ; Zvonek, Miroslav (advisor)
Subject of this Diploma thesis is the design of metal detector and luggage X-ray screening. The thesis concerns with design of frame metal detector and luggage x-ray with focus on visual appeal, keeping of functional elements and concept of construction solution. Main objective is to find solution how to connect aesthetic, ergonomic and technical aspect. Complete analysis leads to design of metal detector and luggage X-ray screening. These appliances then appeal as compact system with uniform design. Also the machines can be used separately. Design of this system of appliances is solved through ergonomic, psychologic, technical and aesthetic aspects.

Modern trends in radiographic procedures and methods in defectoscopy
Skřivánková, Vendula ; Vlašic, František (referee) ; Juliš, Martin (advisor)
Presented thesis deals with modern trends and techniques in radiographic methods of crack detection which are recently used in engineering practice. In the first part, conventional (analogue) radiography principles based on creating a visible image of tested object to radiographic film are discussed. The next part is aimed to the digital radiography and radioscopy. To digitize existing X-ray film images, application of storage phosphor plates (CR), flat panels (DR) and computed tomography (CT).
