Abstract
Study of gamma -ray transmission scanning techniques and image reconstruction process has confirmed the feasibility of the transmission scanning approach to delineation of patient cross-sectional anatomy. Spatial resolution is limited primarily by scanner design considerations such as collimation, and by data handling and storage capabilities and the time available for data accumulation. The data accumulation time can be reduced by using a source with higher photon flux density and by employing selected data processing techniques. By redesign of the source collimator and employment of multiple detectors, cross-sectional images for different planes could be obtained simultaneously. With the approach described here the maximum absorbed dose to the patient is estimated at less than 1 rad. The usefulness in radiation therapy treatment planning of the transmission scanning approach to delineation of cross-sectional anatomy is very promising and currently is being studied.
