Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a medical image X-ray photography positioning device. Background Art

[0002] Oral CT is a medical technology that takes three-dimensional images of oral tissue. In oral CT, the patient's head needs to remain still during the CT examination to avoid forming a virtual image. However, most patients cannot keep their head in the same position during the examination.

[0003] According to a Chinese patent, a medical imaging dental X-ray photography positioning device is disclosed, and its announcement number is: CN211911648U. In this patent, when performing X-ray photography, the patient's head is firmly restrained by at least three sides. The first column can be at least two arranged at intervals in the length direction of the positioning device, and is used to straighten the fixed bracket to reduce the deflection caused by its gravity, so that the deflection of the fixed bracket will not cause deviation to the head fixation as much as possible;

[0004] However, the height of the support block in the patent is fixed and cannot be adjusted, which causes patients of different heights to be uncomfortable with hunched backs when using it. For this reason, we propose a medical imaging X-ray photography positioning device. Utility Model Content
