Abstract

A medical information processing system for supporting diagnostic interpretation, featuring a data storage unit for storing an interpretation image and interpretation reference images for which a doctor will refer to interpret the interpretation image. A data loading unit loads the interpretation reference images from the data storage unit into a workstation unit according to a predetermined priority order. The data loading unit loads the images into a workstation which is selected from the workstation unit according to workstation vs. interpretation examination modality information. A diagnostic information creation unit creates diagnostic information relative to the image by inputting the doctor'"'"'s findings or computerizing with a computer unit. Positions of abnormalities and degrees of the abnormalities are determined, and positions in association with the images are calculated. A diagnostic information comparing unit compares the diagnostic information with each other and creates differences between the diagnostic information as time-sequential abnormality change data. A diagnostic information output unit outputs the diagnostic information or results of comparing the diagnostic information with each other and superimposes the contents of the time-sequential abnormality change data on the associated image. The diagnostic information output unit also outputs predetermined contents for an inconsistency of the diagnostic information for the doctor'"'"'s findings with the diagnostic information for the results of computerizing and includes a plurality of displays and automatically determines relational positions in which the images are displayed on the displays according to a predetermined relational information.
