1418 RTE Pre/Posttest (2023/2024) Already Passed The target material of the anode is made of: Tungsten ____________ radiography systems have detectors that capture and readout an electronic image signal. Direct Filtration removes the ________ energy photons from primary beam. Low Scatter is produced primarily in the _________. a) x-ray tube b) Image receptor c) patient d) target An increase in milliampere seconds (mAs) in digital imaging, increases the signal to noise ratio and ______ the patient dose. a) increase b) decrease c) has no effect d) invalidates The spatial resolution of the digital image is limited by______ Pixel size The ability of phosphors to light up when hit by x-rays is_____. c) fluoroescence To calculate an unknown radiation intensity at a greater or lesser distance from a known radiation intensity and distance the radiographer uses the Inverse Square law An electron has a Negative charge One reason that grids are utilized is to reduce the amount of Patient dose 100 kV is equal to 100,000 The _________ measurement identifiers the biologic effectiveness of the radiation energy absorbed. Effective Dose _________ ensures the electrons flow from the X-ray tube cathode to the anode only. Voltage rectification The___________ standardizes the selection of exposure factors to minimize patient exposure. Technique chart The purpose of filtration is to reduce Patient dose AEC is a radiographic ________ control device that terminates the exposure monitor In direct radiography, the use of ________ as an image receptor capture element amorphous selenium? The higher the number of pixels in a matrix the higher the image resolution X-rays are produced by bremsstrahlung and characteristic X-ray photons exit the tube at the ______ window
