Medical image compression apparatus, medical image compression method, and the prediction knowledge database creation device

摘要

Medical image compression apparatus, a target image is a medical image to be compressed, the compression target acquisition unit that acquires the observation data of the target image (100), based on the findings information, divides the target image into area of ​​each pathology pathological range acquiring section that (130), for any pixel, the prediction knowledge database that holds corresponding to the pixel value included in around a predetermined range, the frequency distribution of the pixel values ​​of an arbitrary pixel in each pathology (180) Referring to, condition of the prediction target pixel, and based on the frequency distribution of the pixel values ​​of the predicted pixel, the pixel value predicting unit for calculating the predicted probability of the pixel value of the prediction target pixel as (190), the pixel value Based on the prediction probability of the prediction unit (190) is a pixel value calculated, an encoding unit for encoding the pixel value of a predicted pixel (200), predicted after being encoded by the encoding unit (200) It comprises an output section for outputting a code of a pixel and the (210).
