LMRT STATE REVIEW 2024 A+ GRADED Q&A

LMRT STATE REVIEW 2024 A+ GRADED Q&A indicator number-how much radiation was absorbed into the phosphors image stitching-stitching together multiple images - useful for scoliosis studies of the spine, long bone studies or angiographic imaging of peripheral vasculature. - to view as a single image. image annotation-allow the technologist to inset preset text or manual text on the image contrast resolution (digital)-Ability to distinguish anatomic structures having similar subject contrast spatial resolution-Refers to the amount of detail present in any image.Phosphor layer thickness and pixel size determines resolution in CR. pixel-A single square within a matrix matrix-a series of very small boxes that form a digital image direct conversion-one step process in DR where flat panel detectors convert the x-ray energy directly to an electric signal using an amorphous selenium detector for immediate viewing charged coupled device-component which light enters and is converted into video or electronic signal thin film transistor-used to read charges collected during an exposure photodiode-A silicon solid state device sensitive to light. Converts light into an electrical signal. scintillator-Amorphous silicon requires a _____ such as cesium iodide or a rare earth intensifying screen composed of gadolinum and lanthanum with oxysulfides. This also converts x-rays to visible light. flat panel detector-a type of digital detector employing amorphous silicon or selenium detector material, bonded with thin-film transistor technology for digital image creation and amplification density-It is the degree of blackening of a radiograph resulting from radiation exposure and processing and one of the two photographic properties that comprise visibility of detail. automatic exposure controll-a device that measures the quantity of radiation that reaches the image receptor and automatically terminates the exposure when the image receptor has received the required radiation intensity high frequency generator-
