PROBLEM TO BE SOLVED: To provide an image diagnostic device and an image storage communication system including the device, wherein a user can easily ascertain that each of components of a movable section should be replaced due to secular changes.SOLUTION: An image diagnostic device (10) includes a data storage section (20a), an operation amount computing section (20c), and a determining section (20b). The data storage section stores the lifetime operation amount the extent to which the summed operation amount of the movable section is required to replace at least some components of the movable section. The operation computing section calculates the summed operation amount when the movable section works. The determining section determines the timing in which at least some components of the movable section should be replaced on the basis of the lifetime operation amount and the summed operation amount.COPYRIGHT: (C)2014,JPO&INPIT【課題】画像診断装置やこれを含む画像保管通信システムにおいて、可動部の部品が交換すべき時期に達したか否かを容易に判断可能にする。【解決手段】一実施形態では、画像診断装置(10)は、データ記憶部(20a)と、動作量演算部(20c)と、判定部(20b)とを備える。データ記憶部は、可動部の積算動作量がどの程度に達した場合に可動部の少なくとも一部の部品を交換すべきかを耐用動作量として記憶している。動作量演算部は、可動部が動く場合に、積算動作量を算出する。判定部は、耐用動作量と、積算動作量とに基づいて、可動部の少なくとも一部の部品の交換すべき時期について判定を行う。【選択図】 図5
