A system processes pixel representative image data of medical images of patient anatomy to automatically identify an interventional instrument. The compound according to the present invention may form a strong molecular hydrogel in a very low concentration of 2 ww % or less. The optical pickup device of the present invention has a semiconductor laser and a photo diode for narrowing light emitted from the semiconductor laser to a predetermined diameter and for detecting light reflected and returned from an optical disc. The relaying server includes a status setting system that sets an operational status of the network facsimile system to a receivable state where the communication terminal can receive the image through the relaying server when the communication terminal has become usable by a user of the communication terminal.
