IMAGE PROCESSING APPARATUS, METHOD AND PROGRAM

摘要

An image obtainment unit obtains plural CT images from an X-ray CT apparatus, and generates a three-dimensional image. A low-resolution image generation unit performs multi-resolution transformation on the three-dimensional image, and generates a low resolution image. A first extraction unit extracts a specific area, such as the liver region, from the low resolution image by using a graph cut method. An outline area setting unit sets the outline of the liver region extracted from the low resolution image in the three-dimensional image, and sets an outline area including the outline in the three-dimensional image. A second extraction unit extracts the outline of the liver region from the outline area, and also extracts the liver region from the three-dimensional image.

主权项

1. An image processing apparatus that extracts a specific area from a processing target image by using a graph cut method, the apparatus comprising:
a first extraction unit that generates a low resolution image of the processing target image, and extracts the specific area from the low resolution image by using the graph cut method; an outline area setting unit that sets, in the processing target image, an outline area including an outline of the specific area in the processing target image based on a result of extracting the specific area; and a second extraction unit that extracts an area corresponding to the specific area from the outline area by using the graph cut method.
