Calibration Strategies for Convergent Beam SPECT and CT
In Single Photon Emission Computed Tomography (SPECT) and Computed Tomography (CT), the geometry of the imaging system determines the encoding of the image information into the acquired data. For convergent beam SPECT, the spatially non-uniform sensitivity due to the collimation further influences this encoding. Accurate image reconstruction requires detailed knowledge of the data encoding, which in turn necessitates careful calibration of the system geometry and sensitivity. This seminar illustrates strategies to achieve such calibration for a variety of experimental SPECT and CT systems. Focus areas are the convenience of use, uniqueness of the result, optimality of the procedure and alternative approaches.
