Radiation Dose In Branch Of Interventional Radiology.
 ŠPERLOVÁ, Šárka
This Bachelor Thesis deals with the issue of radiation load and its impacts on the patient and doctor during the interventional medical help under skiascopy control. The content of the theoretical part describes the medical operations which are carried out, together with the issue of radiation protection within this field with regard to the medical and professional radiation exposure. The main objective of this work determines the estimation of efficient doses of the patient and doctor resulting in the conclusions leading to the decreasing level of radiation load for both parties. For these purposes one-year data were collected into the general database. The PCXMC program was used for calculating efficient doses of the patients collected from the DAP meter. Consequently, collected information regarding the dosage of the patient and doctor were elaborated in the form of charts and graphs. The conclusions were deduced on the basis of available data concluding the hypothesis related to the dependence of radiation rate on the type of medical treatment. It was proved that the highest dosage was achieved with regard to the patients during the embolic medical operations. The lowest dosage for the examining person is during PTD and nefrostomy. The doctors are maximally exposed to the radiation during the liver intervention ? especially during TIPS. The lowest doses received by the doctor were shown during the thrombolytic medical operations. The recommendation leading to the reduction of radiation load at the given workplace of interventional radiology was thus concluded from available information. Besides the correct parameter setting of the appropriate equipment, such as voltage, C-arm´s displacement or OK distance, consistent shielding is also important, especially the use of protective equipment (apron, collars and glasses) and more frequent switching shifts of the personnel
