Extraction of multi organs by use of level set method from CT images

Recently, various imaging equipments have been introduced into medical fields. Especially, HRCT is one of the most useful diagnosis systems because it provides a high resolution image to physicians. Accordingly, many related image processing techniques are proposed into medical fields for extraction of abnormal area. In the medical image processing field, segmentation is one of the most important problems for analyzing the abnormalities and recognition of internal structures before the operation. Many related segmentation techniques have been developed for automatic extraction of regions of interest. Especially, in order to extract multi organs and to understand the structure of them, several approaches have been developed in the past. But there are still no fully automatic segmentation methods that are generally applicable to regions of interest based on CT image set. In this paper, we propose a new technique for automatic extraction of the multi organs on the MDCT images employing the level set method. We apply the proposed technique to three CT cases and satisfactory results are achieved.
