PROBLEM TO BE SOLVED: To easily set an irradiation field in X-ray radiographing in a short time. SOLUTION: A position relation specifying program 141 specifies position relation between the irradiation field and an X-ray detector 5 or 10, based on values which are measured by an X-direction diaphragm angle Thx<SB>1</SB>sensor 110a, an X-direction diaphragm angle Thx<SB>2</SB>sensor 110b, a Y-direction diaphragm angle Thy<SB>1</SB>sensor 110c, a Y-direction diaphragm angle Thy<SB>2</SB>sensor 110d, a tube X-direction angle Thx sensor 110e, a tube Y-direction angle Thy sensor 110f, an X-ray tube supporter position sensor 110g, an X-ray tube to X-ray detector distance sensor 110h, and an X-ray detector position sensor (for supine positioning) 110i or an X-ray detector position sensor (for upright positioning) 110j. Then, the program 141 allows an indicator 11 to display the specified position relation. COPYRIGHT: (C)2008,JPO&INPIT |
