    摘要： A system and method capable of measuring the fat content in the target organ by the gray level distribution of pixels forming a ultrasonic section image and a recording medium of recording a fat content measuring program are disclosed. In order to quantify the fat content of the target organ from the information of the stored ultrasonic section image, a target section and a comparative section in each of the longitudinal sections are set, and a representative gray level value of the respective section is calculated, thereby the fat content of the target section is quantified in a numerical value relative to the representative gray level value of the comparative section.

    摘要： There is provided a method for detecting Ground Glass Opacity (GGO) using chest computed tomography. The method includes detecting a candidate cell having a brightness value within a detection range by sequentially scanning a three-dimensional image of a pulmonary region, and designating the candidate cell as a seed cell when surrounding cells of the candidate cell have brightness values within the detection range; when a plurality of seed cells are obtained by the designating of the candidate cell as a seed cell, grouping adjacent seed cells to obtain one or more candidate zones; and detecting one or more zones, which have a greater size than a GGO detection size and including therein more than the detection reference number of seed cells, out of the one or more candidate zones, and setting the detected one or more zones as one or more GGO candidates.

    摘要： The method of segmenting a lesion in an image according to the present invention includes the steps of: obtaining an image of a region of interest from an image of a lesion; adjusting the contrast of the obtained image of the region of interest such that the contrast changes according to the distance from the center of the region of interest; removing noise from the image whose contrast is adjusted; and separating the region of the lesion from the noise-removed image. In the step of adjusting the contrast, the image is adjusted such that the contrast is increased as it goes away from the center of the region of interest, and thus it is possible to segment the lesion while maintaining the original shape of the lesion, thereby reliably segmenting the lesion even in the case where the inside of the lesion is not uniform.

    摘要： There are provided a method and support device for measuring jawbone mineral density using a jawbone X-ray image. The method for measuring jawbone mineral density includes: obtaining a jawbone X-ray image using a support device for jawbone; defining a region of interest from the obtained jawbone X-ray image; and measuring jawbone mineral density from the defined region of interest. Therefore, the support device for measuring jawbone mineral density may be useful to measure jawbone mineral density with a jawbone X-ray imaging device, which has been widely used in dental clinics, by using the method.
