概要	Doctors have been required to record the numerical information for clarifying the basis of their diagnosis against cases of Hallux Valgus. So, they had to find landmarks in each patient’s X-ray image and calculate the Hallux Valgus (HV) angle. These works were very time-consuming and prevented doctors from seeing many patients. Kind of computer-aided diagnosis systems have been required. We propose a Segment-Anything-based method for X-ray measurement of HV angles. In the method, we first recognize the 1st proximal phalanx and the 1st metatarsal bone by using Segment Anything. Then, both longitudinal directions and their difference were calculated by applying a Principal Component Analysis. In a preliminary experiment using 14 radiographs, the HV angle obtained by the proposed method showed good agreement with the independent X-ray measurements by two doctors.
