Title:
放射線撮影装置
Document Type and Number:
Japanese Patent JP6601230
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a radiographic apparatus capable of accurately adjusting the position of a collimator leaf and setting a radiation irradiating range with a high degree of precision.SOLUTION: A control part 80 includes: an image processing part 81 for executing image processing during slot imaging; a subtraction processing part 82 for executing subtraction processing; and a bone density measuring part 83 for measuring bone density. The control part 80 also includes a slit width setting part 84 for setting the width of an X-ray irradiation field during slot imaging. The slit width setting part 84 includes: an irradiation field width measuring part 85 for measuring the width of a slit-like X-ray irradiation field; a comparison part 86 for comparing the width of the slit-like X-ray irradiation field measured by the irradiation field width measuring part 85 to the setting value of the width of the X-ray irradiation field, and calculating the difference between them; and a position correction part 87 for correcting the position of a collimator leaf based on the difference between the width of the slit-like X-ray irradiation field and the setting value of the width of the irradiation field, which has been calculated by the comparison part 86.SELECTED DRAWING: Figure 3
