This Concept Map, created with IHMC CmapTools, has information related to: ChrisHollyTricha, Predetector collimator function reduces scatter, single breathhold and ability to image large volumes of tissue in less time, pixel when reduced matrix increases, 1st generation consists of single detector, EMT Ltd recorded The Beatles, 4th generation consists of fan beam, reduction in scan time shoter time priciple disadvantage 1 slice requires 20s or longer, Filter back projection uses Interpolation, 2nd generation operates faster reduction in scan time shoter time, spiral CT 1989 reduction in Motion artifacts, 4th generation considered rotate/stationary 1978, Solid state scintillation crystals concentration affects spatial resloution, spiral CT 1989 reconstruction done mathematically called Filter back projection, curvllinear array with many detectors entire patient at all times, detector array ???? analog projection, analog projection record variation in mass density, Slice thickness made of 0.5mm (Squared) pixel size, Slip ring allows Gantry to rotate, prepatient collimator ???? fan x-ray beam, 4th generation considered spiral CT 1989
