The invention discloses a medical imaging clinical scanning device, comprising a bed body, wherein the bed body is provided with a U-shaped plate, and both sides of the bed body are provided with movement grooves corresponding to the ends of the U-shaped plate, A fixed shaft is fixedly connected to the movement slot, and an end of the U-shaped plate is slidably sleeved on the fixed shaft, and an end of the U-shaped plate is connected to an inner side wall of the movement slot through a first limiting mechanism, the U A display screen is rotatably connected to the top of the stencil, and a movable plate is arranged in the U-shaped plate. The invention moves the U-shaped plate, the movable plate and the movable block to move the detector three-dimensionally, thereby facilitating the scanning of the medical worker, and the U-shaped plate is restricted by the first limiting mechanism, and the movable plate is controlled by the second lowering mechanism. The limit position, the third limit mechanism and the control mechanism limit the movable block, thereby facilitating the medical worker to perform fixed-point scanning, and then observing and recording through the display screen.
