摘要： A medical diagnostic system utilizing the principles of nuclear medicine is disclosed. The system includes a gantry having a detector support section supported by a carriage section located on a rail system for movement along a linear path. A nuclear detector is supported on a pair of weighted arms pivotally mounted on the detector support system about an axis perpendicular to the rail system. The detector is itself pivotally mounted near an end of the weighted arm pair for tilting rotation about an axis parallel to the arm pivot axis. Mechanism is provided for rotating the weighted arms additionally about an axis parallel to the rail system, in order to accomplish orbital motion of the detector. All three of these rotational movements are power actuated. A stationary pedestal and cantilevered patient support table is located between the rails of the rail system, with the patient table extending longitudinally with respect to the rails. The upper, or detector supporting section, of the gantry is additionally provided with a degree of freedom wherein it may be rotated about a vertical axis extending through the middle portion of the carriage system, thus disposing the detector for operation at a location alongside, and not between the rails.

摘要： A nuclear cardiology system for use with a scintillation camera for evaluating cardiac function by real time measurement of the variation of radiation from the heart of a patient to whom is administered a radioactive tracer. The camera provides data describing the location of individual counts representing radiation events coming from the patient. The system segregates, in real time, counts corresponding to radiation from an electronically defined region of interest describing an investigated part of the heart, such as the left ventricle. Synchronized by the patient's electrocardiogram, time gated memory circuitry divides each heartbeat into a series of subintervals, and stores indications of the respective amounts of radiation events emanating from the region of interest during each of the subintervals. Calculating circuitry scans the stored information and, based on the maximum and minimum respective radiation amounts detected in the subintervals, computes the fraction of blood ejected by the heart in each beat. A strip chart recorder provides a permanent representation of the curve of radiation from the region of interest, as defined by the indicated series of subinterval radiation amounts.
