Imperfections of the skiagraphs.
 JECHOVÁ, Kateřina
The purpose of my Thesis was to find and document occurrence of imperfect skiagrams in all types of radiographic views, this means classic films, computed radiography (CR) and direct radiography (DR). The research question is "Is there any correlation between number of imperfect skiagrams and number of total skiagrams taken?" I documented rate of imperfect skiagrams in hospital České Budějovice in the time between the years 2013 2015. The Thesis is divided to two main sections: History of Display media and the principle of displaying with all types of displays. Imperfect skiagrams were sorted by origin to: Imperfections caused by operations, imperfections caused by patient and imperfections caused during processing. In my thesis I found out that there is not direct correlation between icreasing number of examinations and number of processed skiagrams. In the reporting period between 2013 2015 there is dependency only in year 2013. In the next two years there is discrepancy in the tracked parameter. The increasing number of examinations and the introduction of new investigative techniques and the rotation of employees (the onset of graduates, as well as radiologists and doctors, their incorporation) are the occurrence of erroneous skiagrams inconsistent with the increasing number of examinations. The monitoring of imperfect skiagrams at the Hospital of České Budějovice is an indicator of the quality of displaying where the upper limit is set at 2.5%. In the reference period, it ranges from 0.2% to 1.76%. Employees are introduced every month and cumulatively once a year to the numbers and types of bad skiagrams to eliminate these errors as much as possible.
