Dose Load during Angiographic Procedures

On basis of dosimetric measurement, this article compares the radiation doses received by the main interventional cardiologist during the angiographic procedures. The dose load during three procedures is compared—LAD-stenting, LCx-stenting and RCA-stenting. An angiographic X-ray system Philips Allura Xper FD10 (with G-arm) was used. The dose obtained was measured with an X-ray-Gamma Dosimeter 27091. During each procedure, two modes of the equipment are used—radiography and fluoroscopy. The dose measurements were made for the respective projections of each angiographic procedure and for the operation modes of the equipment used during the respective procedure at three measurement points on the operator’s body—head, gonads and feet and at three position of the patient’s table—lowest, highest and zero. The results obtained from the calculations, based on the measured dose values, show maximum dose load in the procedure that uses the radiographic mode of operation for the longest time, namely RCA-stenting. The other two procedures have the same time on radiography and fluoroscopy. From them a higher dose load was obtained for the procedure LAD-stenting. Of the three procedures studied, the lowest dose load is obtained for the procedure LCx-stenting.
