20080240494 | CASE IMAGE SEARCH APPARATUS AND SYSTEM - An arbitrary cross-sectional image (MPR image) is used as an image for searching a case DB which has registered case images for a case image similar to an image to be diagnosed. A user terminal produces an axial image with reference to a diseased site in the MPR image, the axial image containing the diseased site, calculates a feature value (first feature value) of the diseased site contained in the axial image, and sends the feature value to the case DB. A case image server compares the received first feature value with a feature value (second feature value) for each case registered in a feature value DB, searches the case DB for a case image having a second feature value similar to the first feature value based on the comparison result, and sends the searched case image to the user terminal. | 10-02-2008 |
20080243395 | IMAGE DIAGNOSIS SUPPORTING APPARATUS AND SYSTEM - In a disease case DB, disease case images are classified by disorder and registered. In a feature quantity DB, a feature quantity (second feature quantity) of each disease case image classified by disorder is registered. A server compares a feature quantity (first feature quantity) of a lesion site included in a diagnosis target image, with the second feature quantity on a disorder-by-disorder basis, retrieves representative disease case images based on a comparison result from the disease case DB on a disorder-by-disorder basis, and provides a user with retrieved representative disease case images. Therefore, the user can obtain disease case images useful for determining a disorder or statistical information and the like regarding the disorder during image diagnosis based on the diagnosis target image. | 10-02-2008 |
20080243886 | CASE DATABASE MANAGEMENT SYSTEM AND METHOD - A case database management system capable of maintaining high quality case information registered in a case DB. A user of the case database management system can not only refer to case information registered in the case DB by user terminals, but also evaluate the case information. The case DB server of the system collects evaluation information evaluated by the user for each case information item and assigns each case information item with an evaluation containing an evaluation point indicating usefulness of the case information. This enables the case database management system to register more highly evaluated (high quality) case information in the case DB and to provide the user with useful case information. | 10-02-2008 |
