indicator number - Answer how much radiation was absorbed into the phosphors image stitching - Answer 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 - Answer allow the technologist to inset preset text or manual text on the image contrast resolution (digital) - Answer Ability to distinguish anatomic structures having similar subject contrast spatial resolution - Answer Refers to the amount of detail present in any image.Phosphor layer thickness and pixel size determines resolution in CR. pixel - Answer A single square within a matrix matrix - Answer a series of very small boxes that form a digital image direct conversion - Answer 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 - Answer component which light enters and is converted into video or electronic signal thin film transistor - Answer used to read charges collected during an exposure photodiode - Answer A silicon solid state device sensitive to light. Converts light into an electrical signal. scintillator - Answer 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 - Answer 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 - Answer 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 - Answer 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 - Answer , What uses AC and DC power converters to change the incoming line from 60Hz to 6000Hz? three phase generator - Answer ... single phase generator - Answer produce a pulsating current that alternates from positive to negative and are power by a single source of ac
