Truncation Compensation in Transmission Reconstructions for a Small FOV Cardiac Gamma Camera |
摘要 |
A method and system for compensating truncated transmission projection data used for attenuation correction in a SPECT apparatus. The method and system include generating an initial estimate of a transmission reconstruction without modeling source geometry or detector collimator response and refining the transmission reconstruction by using the initial estimate with a modified model of the source geometry and the collimation geometry.
