IMAGE PROCESSING APPARATUS, RADIOGRAPHIC IMAGE SYSTEM, AND IMAGE PROCESSING METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of easily clipping a diagnostic region while retaining pixel information on an original radiographic image even when a subject is imaged aslant.

SOLUTION: The image processing apparatus applies trimming processing to a radiographic image acquired by an imaging apparatus for acquiring the radiographic image of a subject and includes: image rotation means for rotating the radiographic image so that the subject is aligned with a given direction to produce a display image; diagnostic region designation means for designating a first diagnostic region clipped with a diagnostic region designation frame represented by a rectangle for the display image; and trimming processing means for calculating a second diagnostic region on the radiographic image from a rotation amount of the display image and diagnostic region information representing the first diagnostic region and applying trimming processing to the radiographic image so as to clip the second diagnostic region.
