Specifically, the distance measuring sensor 11 of the present embodiment may be an infrared sensor or a laser distance meter.

As shown in fig. 1, the DR apparatus further includes a driving mechanism 7 and a photosensitive sensor 8, the driving mechanism 7 is disposed on the base 1, and an output end of the driving mechanism 7 is in transmission connection with the upright 2 to drive the upright 2 to ascend and descend. A photosensor 8 is provided on the flat panel detector 3, and the photosensor 8 can measure the shape of the subject. The driving mechanism 7 can drive the upright post 2 to move up and down according to the measurement result of the photosensitive sensor 8, so that the flat panel detector 3 is aligned with the examined part of the examined person, wherein the examined part is generally the chest or the abdomen of the examined person.

The driving mechanism 7 of the embodiment is a cylinder, the structure of the cylinder is simple, and the control precision is high. The cylinder is vertically installed on the base 1 and can drive the upright post 2 to rise or fall along the vertical direction. The photosensitive sensor 8 is a mature product in the field, and the detailed working principle and working process thereof are not described in detail. When the photosensitive sensor 8 transmits the detected shape feature information to the control module, the control module thereby determines the approximate position of the subject's chest or abdomen and controls the cylinder driving upright 2 to ascend and descend so that the flat panel detector 3 is substantially opposite to the subject's chest or abdomen.
