Description

Technical Field

[0001] The utility model relates to a DR examination auxiliary device, in particular to an auxiliary device for DR examination of the atlantoaxial joint opening position, belonging to the technical field of digital X-ray photography. Background Art

[0002] Digital radiography, also known as DR, is a new digital imaging technology that has similar applications to computed radiography, but differs in its fundamental principles and structure. DR, developed based on digital fluorescence photography, uses an image intensifier tube as the information carrier. It receives X-ray information transmitted through the human body, which is then captured by a video camera and converted into digital signals, which are then digitized.

[0003] The utility model patented as CN218009758U relates to X-ray imaging technology, specifically a DR device. The DR device comprises a base, a column, a flat-panel detector, a tube, a voice system, and a folding arm assembly. The column is arbitrarily mounted on the base, and the flat-panel detector is fixedly mounted on the column. When the folding arm assembly is unfolded, the first, second, and third cantilevers form a U-shaped frame, with the tube facing the flat-panel detector. The examinee can hold onto the U-shaped frame, helping them maintain a stable posture and preventing sway or tilt, thereby improving the quality and efficiency of DR imaging.

[0004] During DR examination of the atlantoaxial joint, the examiner needs to open his mouth so that the atlantoaxial joint can be imaged. Although the DR equipment in the above patent keeps the examinee stable, the opening and closing of the examinee's mouth can easily cause changes in body position, reducing the clarity of the DR image and affecting the accuracy of the DR image. To this end, we provide an auxiliary device for DR examination of the atlantoaxial joint in the open mouth position to solve the above problems. Utility Model Content
