Multiple algorithm lesion segmentation
First Claim
1. A method comprising:
- reading a plurality of medical images from an image repository, a first of the plurality of medical images corresponding to a first body part and having a first source modality, and a second of the plurality of medical images corresponding to a second body part and having a second source modality different from the first source modality, the plurality of medical images being from sequential studies;
registering each of the plurality of medical images to an anatomical atlas, thereby determining an anatomical region depicted in each of the plurality of medical images;
based upon the first source modality and the anatomical region depicted in the first of the plurality of medical images, selecting a first segmentation algorithm for the first of the plurality of medical images;
based upon the second source modality and the anatomical region depicted in the second of the plurality of medical images, selecting a second segmentation algorithm for the second of the plurality of medical images, the second segmentation algorithm different from the first segmentation algorithm;
applying the first segmentation algorithm to the first of the plurality of medical images and the second segmentation algorithm to the second of the plurality of medical images, to annotate a lesion within the first and second of the plurality of medical images;
displaying the results of the first and second segmentation algorithms, thereby providing aggregate results of the sequential studies.

Abstract
Multiple algorithm lesion segmentation using an atlas is provided. In various embodiments, a plurality of medical images are read from an image repository. Each of the plurality of medical images has a source modality. Each of the plurality of medical images is registered to an anatomical atlas. An anatomical region depicted in each of the plurality of medical images is determined thereby. Based upon the source modality and the anatomical region depicted in each of the plurality of medical images, one of a plurality of segmentation algorithms is selected for each of the plurality of medical images. The selected segmentation algorithms are applied to each of the plurality of medical images. The results of the selected segmentation algorithms are displayed.
