Summary

This presentation, given at a nuclear medicine conference, discusses recent advances in hardware and software for quantitative SPECT/CT imaging. The speaker begins by explaining the basics of SPECT, including the use of gamma cameras, collimators, and scintillation detectors. He then highlights the importance of software techniques such as iterative reconstruction and resolution recovery, which model the collimator-detector response to improve image quality and quantitative accuracy. The talk then shifts to hardware innovations, particularly the use of cadmium zinc telluride (CZT) detectors, which offer better energy resolution and sensitivity compared to conventional scintillation detectors. Several commercial CZT-based SPECT systems are described, including dedicated cardiac and whole-body systems. The speaker emphasizes the potential of these systems for dynamic imaging and kinetic modeling, enabling absolute quantification of physiological parameters. The presentation concludes with a discussion of the clinical benefits, such as reduced scan time and improved lesion detection.
