Image diagnosing support method and image diagnosing support apparatus
First Claim
1. An image diagnosing support method comprising:
- acquiring a plurality of images obtained by imaging a same region of a same object with one or more medical imaging apparatuses;
selecting a first image from a first medical imaging apparatus and a second image from another medical imaging apparatus, the first and second images registering a common spatial position of a magnetic sensor, as an alignment reference;
simultaneously displaying said first image and said second image in the same section of the object;
designating one or more of first reference points in an extraction region desired by a user, on said first image;
extracting a first region on said first image on a basis of each of said first reference point and the brightness information on said first image;
automatically designating one or more second reference points on said second image, matching said one or more first reference points, on the basis of the positional information of said first reference points on the first image; and
extracting a second region on said second image on a basis of each of said second reference point and the brightness information on said second image;
wherein the boundary of a region extracted from said first image and the boundary of a region extracted from said second image and said second reference point, are displayed superposed over said second image, and the boundary of a region extracted from said second image and the boundary of a region extracted from said first image and said first reference point, are displayed superposed over said first image, andautomatically adjusting gain and dynamic image parameters so as to match the distribution range of image signal values in the extraction region with maximum gradation range of image displaying to display.

Abstract
This is an image diagnosing support method comprising: an acquisition step of acquiring a plurality of images obtained by imaging the same region of the same object with one or more medical imaging apparatuses and having positional information at the time each of the images was picked up; a selecting step of selecting a first image and a second image out of the plurality of images; a displaying step of displaying the first image and the second image; a step of designating one or more of first reference points on the first image; a step of figuring out second reference points, on the second image, each matching one or another of the first reference points; a first step of extracting for each of the first reference points a first region containing that point within it; and a second step of extracting for each of the second reference points a second region containing that point within it, characterized in that either one of the first step and the second step is performed earlier or both are at the same time.

21. An image diagnosing support apparatus comprising:
-
a selecting unit configured to effect selecting of two or more images out of a plurality of images obtained by imaging a same region of a same object fitted with a registration arrangement causing registration of a common spatial position of the object within each of the plurality of images, the two or more images being obtained by different medical imaging apparatuses; a display unit configured to display the two or more images in the same region of the object; a designating unit configured to designate one or more of first reference points in an extraction region desired by a user, on one of the two or more images as a first image; a first-region extracting unit configured to extract a first region on the first image, on a basis of each of the one or more first reference points, and brightness information, of the first image; an automatic designating unit configured to automatically designate one or more second reference points on a second image of the two or more images, on a basis of the registration of the common spatial position on the first and second images, and the positional information of the first reference points on the first image, the one or more second references points spatially matching the one or more first reference points; a second-region extracting unit configured to extract a second region on the second image, on a basis of each of the second reference point, and the brightness information, of the second image; wherein at least one of;
