Motion correction circuitry and method for a radiation imaging device |
摘要 |
A motion correction method and related analog motion correction circuitry are disclosed, which correct for image blurring due to patient movement in scintigram heart studies using an Anger camera. X, Y positional coordinate signals developed for incident quanta of radiation E1 emitted by an isotope of energy 1 distributed in the heart are displayed on a CRT screen after correction in accordance with the displacement from an initial position &upbar& Xo', &upbar& Yo' of a centroid calculated from X', Y' positional coordinate signals developed for incident quanta of radiation E2 emitted by isotope of energy 2 in the form of a point source strapped to the patient's chest for movement therewith.
