An imaging system in a hospital includes plural diagnostic units each having a picture filing memory in which medical picture data of patients are stored. The memories are located in the diagnostic units at dispersed locations in the hospital. Each diagnostic unit includes a retrieval unit by which image data can be retrieved from the respective memory. A network interconnects the diagnostic unit and permits transmission of image data among the diagnostic units.

Image data management system particularly for use in a hospital

A multi-channel type solid-state X-ray detector includes a base plate, multi-channel photodiodes arranged on the upper surface of the base plate and having one ends connected as output terminals to electrically conductive lines on the base plate, and a number of scintillators disposed on the photodiodes of respective channels, for generating scintillation light corresponding to incident X-rays when the X-rays are irradiated. Those end portions of the scintillators which lie on the other ends of the photodiodes are extended and a light emitting diode arranged in a flat plate configuration is disposed in contact with the underside of the extended portions on the upper surface of the base plate. The scintillators are shielded with respect to light on portions other than the underside which is in contact with the light emitting diode and photodiodes by reflective coating material or the like, and light from the light emitting diode is permitting to be projected into the entire portion of the scintillators. The light projection compensates for radiation damage of the scintillators and prevents the detection sensitivity of the scintillators from being lowered.

A database system is provided in a network system capable of exchanging medical data, including at least image data and key data associated therewith, and can store and retrieve the medical data via the network system. The database system has first and second data file devices and a file management device. The first data file device stores image data supplied via the network system in a first rewritable storage. The second data file device stores image data transferred from the first storage in a non-rewritable second storage. The file management device has an index data storage for storing the key data, supplied via the network system, and memory addresses of image data, which correspond to the key data, on the first and second storages in correspondence with each other, and manages storing and reading of the image data in and from the first and second data file devices.
