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.
Claims6
A method of 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 emitted radiation from a first projectional view of said plurality of projectional views to produce uncompensated emission data for said first projectional view;
- irradiating said first projectional view with radiation from said radiation source to produce transmitted radiation through said first projectional view;
- and
- detecting the transmitted radiation and the emitted radiation from said first projectional view to produce transmission data for said first projectional view;
- then
- detecting emitted radiation from a second projectional view of said plurality of projectional views to produce uncompensated emission data for said second projectional view;
- irradiating said second projectional view with radiation from said radiation source to produce transmitted radiation through said second projectional view;
- and
- detecting the transmitted radiation and the emitted radiation from said second projectional view to produce transmission data for said second projectional view.
