摘要:
The present invention relates to a radiation image processing apparatus and a processing method. A processing condition selector selects from a processing condition memory a processing condition for extraction or removal of a specific object in radiation image information. The processing condition includes two different image capturing conditions which are provided to a radiation source controller. The radiation source controller controls a radiation source with each image capturing condition to apply radiation to a subject and a solid-state radiation detector stores radiation image information of the subject. An image processor performs a weighted subtraction using stored radiation image information in accordance with the processing condition to achieve extraction or removal of the specific object. The resultant radiation image information is displayed on a display unit.
