  • Method and apparatus for enhanced single photon computed tomography
    Patent number: 5289008
    Abstract: Disclosed is a method and apparatus for single photon emission computed tomography of a test region having a plurality of projectional views utilizing a radiation source opposite said test region from a radiation detector, comprising detecting emission radiation from a first projectional view of a test region, irradiating the test region to transmit radiation through the test region, and detecting both emission and transmission radiation from the first projectional view of the test region. The emission detection, irradiation and emission and transmission steps are then repeated for a second projectional view. This emission and transmission data may then be used to produce compensated emission data for the test region.
