Method for constructing a data base in a medical image control system
First Claim
1. A method for constructing a data base in a medical image control system in which image signals representing medical images are filed on a recording medium and said image signals are retrieved by use of said data base,said method comprising the steps of recording image retrieval signal data in said data base, said image retrieval signal data including information indicating the time at which each medical image is recorded, a rank of importance for each medical image, and a number indicating how many times the image signals corresponding to each medical image filed on said recording medium base have been retrieved;
- incrementing said number each time a corresponding image signal is retrieved; and
, when said data base is full of image retrieval signal data, deleting the image retrieval signal data corresponding to the image signals of the medical image in which at least (i) said time at which said medical image is recorded is earlier than a predetermined time and (ii) said rank of importance of said medical image is lower than a predetermined value.

Abstract
A method for constructing a data base in a medical image filing system comprises the steps of recording information indicating the time at which each medical image is recorded and a rank of importance for each medical image as image retrieval signal data for image signals corresponding to each medical image; recording the number of times the image signals corresponding to each medical image have been retrieved as image retrieval signal data and incrementing said number each time the image signals are retrieved; and when the data base is full of image retrieval signal data, deleting the image retrieval signal data corresponding to the image signals of the medical image in which at least (i) the time at which said medical image was recorded earlier than a predetermined time and (ii) the rank of importance of the medical image is lower than a predetermined value.
