Embodiment Construction

[0011] Hereinafter, an X-ray computed tomography apparatus and an information processing apparatus according to the present embodiment will be described with reference to the drawings.

[0012] figure 1 It is a figure which shows the structure of the X-ray computed tomography apparatus concerning this embodiment. Such as figure 1 As shown, the X-ray computed tomography apparatus according to this embodiment has a gantry 10 and a console 30 . The gantry 10 is installed in a CT imaging room such as a hospital. The console 30 is installed in a CT imaging room, a control room adjacent to the CT imaging room, or the like. The console 30 controls the gantry 10 in accordance with instructions and the like from an operator.

[0013] The stand 10 is equipped with a rotating frame 11 in a casing (not shown) formed with an opening. The rotating frame 11 is accommodated in the casing so that the central axis Z of the casing coincides with the central axis (rotation axis) Z of the rot...

Abstract

A reconstruction unit (a pre-processor, a reconstruction unit and an image processor) generates a reconstruction image based on output from the X-ray detector. A correction parameter storage stores correction parameters in time series, the correction parameters being used for correction by which noise or artifact is reduced in processing performed by the reconstruction image unit. A correction parameter analysis unit determines whether or not an abnormal condition occurs based on a temporal change in the correction parameters stored in the correction parameter storage. A notification unit issues a notification indicating the occurrence of an abnormal condition where the correction parameter analysis unit determines that the abnormal state has occurred.

Description

technical field [0001] This embodiment relates to an X-ray computed tomography apparatus and an information processing apparatus. Background technique [0002] Currently, abnormal states of X-ray computed tomography apparatuses are often detected. For example, an abnormality of an X-ray computed tomography apparatus can be confirmed by observing an error log or reconstructing an image. At this time, the change in the state of the device cannot be noticed unless it is in an abnormal state. In addition, there is also a method of detecting an abnormal state by performing a CT scan on a phantom for image quality analysis at the time of periodic maintenance or the like. In this method, an abnormality is detected by checking the output of an X-ray detector by a service person or the like, reconstructing an image, or automatically analyzing by analysis software. In this case, only periodic confirmation is possible. Contents of the invention [0003] An object of the embodimen...
