Head acquisition contour tracking device of nuclear medicine equipment detector

The invention discloses a head acquisition contour tracking device of a nuclear medicine equipment detector, and relates to the technical field of medical equipment. Comprising a supporting frame, a detector body and a contour tracking device, a bottom plate is fixed to the bottom end of the supporting frame, rotating plates are rotationally connected to the two sides of the bottom plate, a transverse shaft is connected to one side of each rotating plate in a rolling mode, and the detector body is connected with the transverse shaft through a vertical plate; the contour tracking devices are arranged on the opposite sides of the two rotating plates. The rotating plate and the driving device for driving the rotating plate to rotate are arranged, before use, the detector body is located at the avoiding position, a patient can directly sit on the seat, and during use, the driving device drives the detector body to vertically move downwards, so that the detector body is located on the front side and the rear side
