In the past, in order to perform MQC, it was necessary to record by handwriting on the device operation parameter sheet 15. Therefore, when the user is busy, it is not recorded or is recorded by mistake. It was difficult to collect accurate information using the operating parameter 15. If accurate information cannot be collected, when a trouble occurs, the amount of information for investigating the cause of the trouble is insufficient, and the downtime of the radiotherapy apparatus increases with the trouble repair time. If the downtime increases, the planned treatment may not be able to be carried out smoothly, and the treatment effect itself may be adversely affected.

Further, since the work efficiency is low, the MQC management work and the maintenance work increase, and the cost related to them increases. Therefore, in many cases, accurate information is not notified to the service center or the manufacturer, and there is a problem that the downtime of the device when a trouble occurs and the service cost increases.

The present invention has been made to solve the above problems, and provides a radiation treatment apparatus and a radiation treatment apparatus management system capable of automatically collecting information on the operating status of the radiation treatment apparatus.
