    • PROBLEM TO BE SOLVED: To improve operability in measurement of a sharp angle of a hip joint image and to prevent an erroneous diagnosis. SOLUTION: The hip joint image is displayed on the monitor screen of a display part, and a reference auxiliary line passing through left and right tear drop lower ends, an oblique auxiliary line passing through the right tear drop lower end and a right acetabular outer side edge, and an oblique auxiliary line passing through the left tear drop lower end and a left acetabular outer side edge are drawn. The formula of a straight line L which passes through an end point equivalent to the right side of a human body of the reference auxiliary line and is vertical to the reference auxiliary line is obtained (step S25), the coordinates of intersections of the reference auxiliary line and the respective oblique auxiliary lines are respectively obtained (steps S26, S27), and the one at a shorter distance from the straight line L is determined as the oblique auxiliary line equivalent to the right side of the human body relatively (step S28). An angle formed by the oblique auxiliary line equivalent to the right side of the human body and the reference auxiliary line is defined as a right sharp angle (step S29), and an angle formed by the oblique auxiliary line equivalent to the left side of the human body and the reference auxiliary line is defined as a left sharp angle (step S30).
