Abstract
A picture archiving communication system for medical application includes least one work station, a data base, including a low-speed recording medium and a high-speed recording medium, for storing image data collected by a diagnosing apparatus unit. When a transfer command for desired image data is sent from the work station to the data base, the image data from the image data registered in the data base is read-out to the work station. A migration processing unit copies image data stored in the low-speed recording medium to the high-speed recording medium in the data base. A file management unit is provided, including a management table for storing a migration index number corresponding to at least one image data in the high-speed recording medium, which was subjected to the migration processing, and including a record indicating whether the image data stored in the high-speed recording medium was accessed after the migration processing. This system may further determine whether the image data stored in the high-speed recording medium from the management table has been accessed, and, if the image data has been accessed, deleting the image data from the high-speed recording medium from the earliest accessed one.
