Abstract

The use of rotating quadrant slant-hole (RQSH) collimation in single photon emission computed tomography (SPECT) scintimammography (SM) is investigated. A RQSH collimator acquires a complete set of projection data for fully 3-D reconstruction of the breast with 90 degrees of collimator rotation at each of 2-3 collimator-detector positions around the breast. The use of a 90-120 degree arc allows the collimator to remain close to the breast throughout the data acquisition, providing better resolution in the reconstructed image as compared to the conventional parallel-hole collimation SPECT acquisition. In addition, a RQSH collimator for SPECT SM has 2.8-3.5 times the efficiency of a conventional parallel-hole collimator with equivalent resolution.
