METHOD AND DEVICE FOR GENERATING ENERGY SUBTRACTION PICTURE

摘要

PROBLEM TO BE SOLVED: To generate an energy subtraction picture whose noise component is effectively reduced in a simple processing process taking a short processing time. SOLUTION: In the device, there is provided a high tension image granularity suppression means 10 applies granularity suppression processing to high tension image data Sh in the high tension image data Sh and low tension image data SL and with an arithmetic means 20 that generates bone image data S1 mainly representing a bone image in an object and soft image data S2 mainly representing soft image such as a bronchial on the basis of high tension image data Sh' whose granularity component is suppressed by the high tension image granularity suppression means 10 and the low tension image data SL.
