 note = {Diseases of the cervical spine often cause more serious disabilities in activities of daily living than diseases of other parts of the body, and thus require prompt and accurate diagnosis. One of the indicators to diagnose cervical spine diseases is to measure the range of motion angle. The main measurement method is manual, which is a burden for doctors. In this paper, we investigate the possibility of measuring the range of motion angle of the cervical spine from cervical X-ray images using Mask R-CNN and image processing. As a result of measuring the range of motion angle with the proposed cervical spine motion angle measurement aid system, the mean error from the true value was 3.1 degrees and the standard deviation was 2.5 degrees. The standard deviation of the specialist measurements was 2.9 degrees, while that of the proposed system was 0 degrees, indicating that there was no variation in the measurements of the proposed system., Diseases of the cervical spine often cause more serious disabilities in activities of daily living than diseases of other parts of the body, and thus require prompt and accurate diagnosis.
