Patent Images
1. A method for classifying regions within a medical image, comprising the steps of:
- training a classifier on a set of medical image training data, which training data includes segmented regions where a clinical ground truth classifying the segmented regions is known;
acquiring non-training medical image data for investigation;
processing the training data to identify and segment regions of morphological interest, using a process for computer assisted detection (CAD);
processing the segmented regions to extract a full feature set for each of the segmented regions; and
classifying the regions of interest using the feature sub-set;
wherein, the step of training includes using a recommender to realize a stable segmentation.

Abstract
A method for segmenting regions within a medical image includes evaluating a set of candidate segmentations generated from an initial segmentation. Based on distance calculations for each candidate using derivative segmentations, the best candidate is recommended to clinician if it is better than the initial segmentation. This recommender realizes a most stable segmentation that will benefit follow-up computer aided diagnosis (i.e. classifying lesion to benign/malignant).

- 4. A segmenter for segmenting or delineating a particular region of interest within a medical image, and generate a candidate segmentation for the region, wherein the segmenter includes a recommender to generate a plurality of segmentations by varying or perturbing the candidate segmentation boundaries, wherein if the segmenter determines the recommended segmentation is better suited for post segmentation processing, it recommends changes to the clinician candidate region, based on the perturbations in order to improve the segmented accuracy.
