Abstract
In positron emission tomography, a nuclear medicine scanner is utilized to detect γ-ray events resulting from positron annihilation events. Molecules with known behaviors are tagged with radioactive isotopes which decay into γ-ray pairs which are detected coincidentally, i.e. in a near-simultaneous fashion, by radiation detectors. A temporal recorder and a subject support monitor indicate the time and position of the subject when the coincident γ-rays were detected. A storage buffer collects γ-ray detection times and locations along with support positions. Every 1/100- 1/10second, a batch of data collected in the buffer is reconstructed into overlapping portions of an image memory as the support moves continuously through the scanner.
