Abstract: A learning unit in learning mode generates a cluster from a cluster analysis of data formed from frequency constituent data and state data, obtained from a sensor unit. An abnormality calculation unit computes, as abnormalities, the minimum values among distances to surfaces of the clusters of the data formed from the frequency constituent data and the state data, obtained when in predictive fault indicator sensing mode. A predictive fault indicator determination unit determines a predictive fault indicator of an X-ray tube by comparing the abnormalities with a predetermined threshold.

Abstract: Times in association with a portion of data designated by an input device from a graph indicating distribution of data of a certain item are divided into plural groups based on the respective time intervals, data relating to desired items included in time ranges respectively regulated by the plural groups are searched from a storage device, and time waveforms of data relating to the desired items are created for each of the groups based on the search results. With this configuration, around the time of generating a portion of data included in a set of data relating to a certain item, aspects of temporal changes of data of a certain item or other items can be easily recognized.
