Fluoro questions with correct answers

what are the factors that directly influence the exposure rate at the panel or tabletop and the patient and the operator's radiation dose? Answer milliamperage, kilovolatage, collimation, filtration, exposure time, target to panel (tabletop) distance (TPD), patient to image intensifier distance for over the table and under the table image intensifier systems, sensitivity of the image receptor what will reduce patient exposure? Answer 1.Collimation to the area of clinical interest only (required by regulations), "last frame hold" or last image hold" fluoroscopy ng the patient to detector distance or patent to image intensifier distance as short as practicable the highest kilovoltage and lowest milliamperage practicable 5. Pulsed fluoroscopy, particularly with lower frame rates 6. Using the largest image intensifier mode (non magnification with strict collimation what are the factors which indirectly influence the exposure rate by impacting the use of technical factors? Answer 1. illumination or lighting in the fluoroscopy room
