A method and apparatus for diagnosing and/or calibrating underperforming pixels in detectors in a small pixelated photon counting CT system utilizes a series of tests on image data acquired in-situ as part of a series of calibration scans in the CT system. Tests are performed on the acquired data to determine the existence of underperforming pixels within the detectors such that the information acquired by those pixels can be replaced by alternate data from surrounding pixels (e.g. by interpolation). The underperforming pixels are stored in “bad” pixel tables and may be specific to a type of image (e.g., spectral or counting) and a specific protocol.

According to one embodiment, an X-ray diagnostic apparatus includes processing circuitry. The processing circuitry is configured to execute first calculation processing of calculating three-dimensional position information of each of an X-ray generator and an X-ray detector during rotation imaging, based on projection data acquired by executing the rotation imaging for a phantom with the X-ray generator and the X-ray detector arranged rotatably around the phantom.

A wide area cosmogenic neutron sensor is used for detecting moisture within a measurement surface. A neutron detector is positioned on a stand structure holding the detector above a measurement surface. A moderator material and neutron shield are positioned around at least a portion of the neutron detector. The neutron shield substantially covers an entirety of a bottom of the neutron detector and is not positioned on a top side of the neutron detector. Wide area cosmogenic neutrons propagating from the measurement surface travel through an air space before arriving at the moderated neutron detector.
