Paper Abstract

The technology of computerized-tomographic scanners is rapidly evolving. Current body scanners employ fan beams of x-radiation in combination with large arrays of Xenon-ionization or scintillation-phototube detectors. Two-motion or pure rotary scanning configurations are used. Curent specifications include: scan times of 5 seconds, image matrices up to 512 x 512 , processing times of tens of seconds and spatial resolution in the range of 1.5 mm FWHM. A typical current scanner, the EMI-5000 has been characterized with respect to noise, detectability, resolving power, motion artefact, dosimetry, and precision.
