Often in medical imaging, a “one size fits all� approach to acquiring data is not appropriate. Imaging acquisitions are usually tailored to specific clinical indications, and usually need to be adjusted as a function of patient size. Recent advances in patient-specific imaging have allowed even finer tuning of imaging parameters to specific patients. Modern scanners and research efforts are incorporating aspects of a patient’s presentation like heart-rate patterns, local body composition, and the degree of vasculature (i.e. blood volume) supplying a tumor. Tuning to these characteristics allows images to be acquired faster, with better image quality, or at lower doses of ionizing radiation. This session will survey the existing clinical methods of patient-specific imaging methods and discuss some current research efforts in this niche. Patient specific: collimation for nuclear medicine SPECT studies, customization of pulse sequences for MRI, heart-rate and fluence-field modulation for CT, and PET patient location specific couch dwell times will be presented respectively.
