Abstract
The disclosed embodiments relate to a system that performs ultra-fast tracer imaging on a subject using positron emission tomography. During operation, the system performs a high-temporal-resolution, total-body dynamic PET scan on the subject as an intravenously injected radioactive tracer propagates through the vascular system of the subject to produce PET projection data. Next, the system applies an image reconstruction technique to the PET projection data to produce subsecond temporal frames, which illustrate the dynamic propagation of the radioactive tracer through the vascular system of the subject. Finally, the system outputs the temporal frames through a display device.
