Claims (1)

[Scope of Claim for Utility Model Registration] (1) A detector that moves up and down centering around the test area of a patient lying in a fixed position on the bed, and at least one detector that detects the upper surface of the test part in accordance with the detector. 1. A near-orbit ECT device, characterized in that two sensors are combined, and signals from the sensors are sent to a gantry controller to control vertical movement and rotation of the detector. (2) Using three sensors, at the start of ECT, the detector's vertical movement motor decelerates the detector until it detects the signals of the first and second sensors, and then decelerates the detector at low speed until it detects the signal of the third sensor. The proximity track according to claim 1 of the utility model registration, characterized in that the track is controlled so that it approaches the inspection part, stops, collects data, and then moves away until it detects a signal from the first sensor. ECT device.
