摘要： Disclosed herein are a system and method for contouring a set of medical images. The system for contouring a set of medical images receives a medical image set including a plurality of medical images via the communication interface module, receives region-of-interest (ROI) information as an object for the drawing of a contour via the user interface module, checks whether a contour corresponding to the ROI information has been drawn on a target image currently displayed to a user, predicts a contour candidate based on contouring conditions if the contour corresponding to the ROI information has not been drawn on the target image, and displays the contour candidate on the target image. The contouring conditions include the relevance between at least one source image, on which the contour corresponding to the ROI information has been already drawn, and the target image, and anatomical information related to the ROI information.

摘要： Disclosed are a computing system and method for identifying and visualizing a thrombosis. The method includes: registering an acquired computer tomography (CT) image of an examinee and a computer tomography angiography (CTA) image-based average standard model to each other; identifying a candidate blood vessel region from the CT image based on the results of the registration; acquiring a volume, selected by applying a threshold value for the brightness of the CT image to the candidate blood vessel region, as a first thrombosis candidate region; acquiring at least part of the first thrombosis candidate region as a second thrombosis candidate region based on the size information of the first thrombosis candidate region; and visualizing the second thrombosis candidate region by assigning a visual effect, adapted to distinguish the second thrombosis candidate region from the remaining portion of the CT image, to the second thrombosis candidate region.

摘要： Disclosed is a patient case identity determination method for a digital pathology system, which is performed by a patient case identity determination unit. The patient case identity determination method includes acquiring a digital slide image from a scanner; requesting a laboratory information system (LIS) to send patient/case information including a preprocessing step image that is obtained in a digital slide preprocessing step associated with the digital slide image; receiving the patient/case information including the preprocessing step image from the LIS; comparatively analyzing a pattern of the digital slide image and the preprocessing step image to calculate a synchronization rate and stores the calculated synchronization rate; and providing information about whether the digital slide image is identical to the patient/case information based on the calculated synchronization rate when a client application provides a reading of the digital slide image.

摘要： Disclosed is an image compression method of a digital pathology system. The image compression method is a method of compressing digital slide images having first to nth original plane images (n is a natural number greater than or equal to 2). The image compression method includes selecting a block having an optimal focal point as an optimal block from each set of blocks positioned at identical positions of the first to nth original plane images; forming one plane image as a virtual optimal plane image by combining only the optimal blocks; generating block descriptors for forming the first to nth original plane images based on the virtual optimal plane image; generating first to nth predictive plane images from the virtual optimal plane image such that the first to nth predictive plane images are the least out of focus by using location information for the blocks and the block descriptors; generating first to nth differential plane images, the first differential plane image corresponding to a difference between the first original plane image and the first predictive plane image and the nth differential plane image corresponding to a difference between the nth original plane image and the nth predictive plane image; and compressing the first to nth differential plane images.
