Dopamine Transporter SPECT with 12-Minute Scan Duration Using Multiple-Pinhole Collimators

Journal of Nuclear Medicine
Visual Abstract This study evaluated the potential to reduce the scan duration in dopamine transporter (DAT) SPECT when using a second-generation multiple-pinhole (MPH) collimator designed for brain SPECT with improved count sensitivity and improved ...

Twisted clustered pinhole collimation for improved high-energy preclinical SPECT/PET

Physics in Medicine & Biology
Abstract Objective. Advanced pinhole collimation geometries optimized for preclinical high-energy ɣ imaging facilitate applications such as ɑ and ß emitter imaging, simultaneous multi-isotope PET and PET/SPECT, and positron range-free PET.
