A series of questions and answers related to fluoroscopic protection features, covering key aspects of radiation safety in fluoroscopy. It includes topics such as the location of the x-ray tube and image intensifier, source-to-skin distance, and the impact of changes in ssd on output intensity. The material also addresses minimum ssd requirements for stationary and mobile fluoroscopes, the function of the image intensifier, and the automatic adjustment of mas during fluoroscopy. Further questions cover primary protective barriers, filtration requirements, collimation, and the use of deadman switches. The document also details the function of bucky slot covers, protective curtains, cumulative timers, and maximum exposure limits, as well as the concept of dose area product (dap) and its significance in risk assessment. This resource is useful for students and professionals in radiology seeking to review and reinforce their understanding of radiation safety protocols in fluoroscopy.

Fluoroscopic x-ray tube - correct answer ✅Part of a fluoroscopic imaging system that is located under the table, opposite of an x-ray tube which is above the table Image intensifier - correct answer ✅Part of a fluoroscopic imaging system that is located above the table Source to skin distance - correct answer ✅The distance from the x-ray tube to the skin Changes in SSD - correct answer ✅Will cause changes in output intensity of the x-ray tube to adjust the brightness of the image being seen by fluoroscopy Increase in mA - correct answer ✅Will result from an increase in distance in fluoroscopy
38 cm - correct answer ✅Minimum SSD of stationary fluoroscopes 30 cm - correct answer ✅Minimum SSD of mobile fluoroscopes Image intensifier - correct answer ✅Receives x-rays from under the table and turns them into light using a photomultiplier tube. mAs - correct answer ✅Is automatically adjusted during fluoroscopy by the image intesifier Primary protective barrier - correct answer ✅Type of protective barrier provided by the fluoroscopic image receptor assembly 2 mm Pb equivalent - correct answer ✅Amount of material of the fluoroscopic image receptor that act as a primary barrier
approriate size when the height of the fluoro tower is changed Deadman - correct answer ✅Type of exposure switch that should be used for fluoroscopy Exposure activates - correct answer ✅Occurs only when weight is applied to a pedal or pressure to a switch during fluoroscopy Bucky slot cover - correct answer ✅Covers the space, where x-rays can pass through from the fluoro tube, left by the bucky tray being moved to the end of the table 0.25 mm Pb equivalent - correct answer ✅Minimum amount of material of the bucky slot cover Protective curtain or panel - correct answer ✅Should be situated between the patient and the operator
0.25 mm Pb equivalent - correct answer ✅Minimum amount of material of the protective curtain or panel Cumulative timer - correct answer ✅Produces an audible sound when fluoro time reaches 5 minutes and is activated when exposure is activated 2.1 R/min or 21 mGya/min - correct answer ✅Maximum intensity of the x-ray beam at the table top of a fluoroscope 10 R/min or 100 mGya/min - correct answer ✅Maximum amount of exposure during fluoroscopy when there is no optional high-level control 20 R/min or 200 mGya/min - correct answer ✅Maximum amount of exposure during fluoroscopy when there is an optional high-level control
