CT Registry- Image Production All Answers Correct

CT Registry- Image Production All Answers Correct Fundamental principle of ct may be summarized as ️An image of an object may be reconstructed on the basis of the attenuation that occurs as x radiation is transmitted through it Detectors measure ️The radiation that is transmitted through the pt. An image is reconstructed in the basis of the magnitude of X-ray attenuation that occurs at spatially distributed points within the pt General process of ct imaging imaging may be divided into several steps- ️Data acquisition- measurement of the attenuation that occurs along each path through the pt from X-ray tube to detector Data reconstruction- computerized processing of the transmission measurements into the ct image Multidimensional image display- display of the reconstructed grayscale image in two dimensional and or 3D format. A representation of the attenuation that occurred across the scanned volume of tissue Image archival and communication- display as well as storage, both short term and long term (archival) of images on computer workstations Most basic scan mode by ct ️Scout image acquisition. This survey scan is a digital radiograph obtained by keeping the X-ray tube and detector array in a fixed position while the pt bed is translated through the gantry Scout aka ️Scanogram or localizer. Scout may be AP, PA, lateral, or oblique Azimuth ️The angle of the tube and detectors in relationship to the pt position during scout acquisition Ct system consists of ️Powerful computer, display system, bed, gantry components The gantry houses the ️Majority of mechanical components of ct system operation including the
