LDR and HDR brachytherapy in the treatment of breast cancer - a role of radiological assistant
Michalová, Zuzana ; Kmoníčková, Emanuela (advisor) ; Kindlová, Anna (referee)
I have selected the comparison of brachytherapy irradiation of breast as a theme for my bachelor work. This comparison is demonstrated on two afterloading machines. The first machine is older and less frequent type of device - microSelectron LDR. This machine contains sources of low dose rate, isotope Cs 137. The second is more modern and more frequent type around the world - microSelectron HDR. This device contains one source of high dose rate isotope Ir 192. Both devices are produced by the Holland Company Nucletron. I focus primarily on a description of radiologic assistant work. Device cont rol and check up belongs to my main responsibilities. Check up is performed according to the program of quality assurance formatted by our organization and according to tests distributed by SÚJB. Whole test program consists of two main exams: Operational stability testing and assistance to the physicist within longtime stability testing. Operational testings are selected according to the type of device: Pre - application, monthly, bi-monthly, semiannual and annual testing period. Our Organization does not us e system DICOM. It was implemented only recently, some half year ago. Therefore I had to document the brachyterapy applications on X-ray films. Currently the DICOM system allows to transfer X -ray images directly...

The role of the radiologist assistant in brachytherapy
Jašková, Ivana ; Malinová, Běla (referee) ; Kindlová, Anna (advisor)
The thesis deals with the description of the role and procedure of a radiographer at individual types of brachytherapeutical applications. It summarizes the history of brachytherapy, its division according to the localization of the source of ionizing radiation, according to the length of irradiation and the dose rate of the source. It describes the principle of both manual and remote afterloading, it indicates the sources of ionizing radiation and used values and units. It deals with individual types of brachytherapy - interstitial, intracavitar, intraluminal and surface ones, describes their application at existing types of tumour diseases and specifies the workload of particular members of brachytherapeutical team at applications.
