METHOD AND SYSTEM FOR AUTOMATED MULTI-SAMPLED DETECTION OF LESIONS IN IMAGES

摘要

Method and system for automated detection of lesions in medical images using multi-sampling. An image is obtained and digitized. A multi-sampling (30) technique is used to generate a plurality of sampled images by sampling the digital image a corresponding plurality of times. The sampled images will have subtle differences from each other. All or a selected number of the sampled images are subjected to a lesion detection routine to detect regions suspected of being a lesion. The results of the detection are compared and regions that appear in less than a predetermined number of the sampled images are determined to be a false positive and eliminated. The remaining regions are determined to be a true positive. The detected lesions (13) could then undergo further analysis such as feature extraction (36) and feature analysis. Using the method and system according to the invention, the number of false positives can be reduced, improving the sensitivity of the automated detection.
