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.

摘要： An alignment apparatus and a program that improve the accuracy of alignment between two radiation images are provided. For each of portions of the two radiation images, evaluation means calculates an evaluation value that evaluates an amount of positional shift regarding a tissue radiographed in the radiation images, and search condition setting means sets for each of the portions a condition of search for corresponding positions between the two radiation images based on the evaluation value. According to the search condition having been set, alignment means searches for the corresponding positions between the two radiation images, and aligns the two images by warping at least one of the radiation images.
