AB We have developed an approach to detect and correct patient motion that occurs during SPECT imaging. The detection of patient motion is based on frame-to-frame matching, using phase-only matched filtering (POMF). The correction procedure has been designed to correct any translational patient motion and alert the operator to other kinds of patient movement. The precision in correcting translational motion is less than 1 pixel in the axial direction and less than 2 pixels in the lateral direction. Experiments on phantom and patient data have demonstrated that our approach is a reliable, accurate, and sensitive method for detecting and correcting patient motion in SPECT imaging.
