Method of reviewing tomographic scans with a large number of images
First Claim
1. A diagnostic medical imaging system comprising:
- an imaging apparatus having an examination region in which a subject being examined is portioned, said imaging apparatus obtaining a plurality of first image slices of the subject, said first image slices having a first resolution;
a storage device into which the first image slices are loaded;
a data processor which combines subsets of first image slices to generate a plurality of second image slices having a second resolution lower than the first resolution, said subsets each including a number n of contiguous first image slices; and
, a display having a plurality of view ports including a first view port which depicts one or more selected second image slices and a second view port which depicts one or more first image slices which are constituents of one of the second image slices depicted in the first view port.

Abstract
A diagnostic medical imaging system (10) includes an imaging apparatus (100) having an examination region (112) in which a subject (20) being examined is portioned. The imaging apparatus (100) obtains, at first resolution, a plurality of first image slices of the subject (20). The first image slices are loaded into a storage device, and a data processor combines subsets of first image slices to generate a plurality of second image slices having a second resolution lower than the first resolution. The subsets each includes a number n of contiguous first image slices. A display (152) having a plurality of view ports including a first view port which depicts one or more selected second image slices and a second view port which depicts one or more first image slices which are constituents of one of the second image slices depicted in the first view port.

6. A diagnostic medical imaging system for examining a subject, said diagnostic medical imaging system comprising:
-
acquisition means for obtaining a plurality of first image slices of the subject, said first image slices corresponding to a first thickness;
combining means for generating a plurality of second image slices from combined subsets of first image slices, said subsets including a number n of contiguous first image slices, said second image slices corresponding to a second thickness which is n times the first thickness;
first display means for displaying one or more selected second image slices; and
,second display means for displaying one or more of the first image slices included in the subset used to generate one the second image slices being displayed by the first displaying means. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

(a) obtaining a plurality of first image slices of a subject, said first image slices corresponding to a first thickness;
(b) generating a plurality of second image slices from subsets of first image slices, said subsets including a number of contiguous first image slices, said second image slices corresponding to a second thickness greater than the first thickness;
(c) designating regions of the subject for close review by a reviewer;
(d) sequentially displaying the second image slices for review by the reviewer; and
,(e) displaying the first image slices for review by the reviewer when the designated regions are reached. - View Dependent Claims (16, 17, 18)
