Abstract: A positron emission tomography (PET) apparatus according to an embodiment includes a PET detector and processing circuitry. The PET detector includes a detector ring configured with a plurality of detector modules arranged in an annular shape. The processing circuitry is configured to acquire information regarding a scan mode of a PET scan for a subject. The processing circuitry is configured to control a relative position of the detector modules in an axial direction of the detector ring based on the information.

Abstract: An X-ray image diagnostic system of an embodiment includes processing circuitry. The processing circuitry is configured to acquire an image obtained by imaging a plurality of detection elements that output signals in response to incident X-rays, and a plurality of scattered radiation removal plates arranged at least in a channel direction on the side of a first surface of the plurality of detection elements on which the X-rays are incident in a direction substantially normal to the first surface, and generate data regarding an irradiated area of each of the plurality of detection elements on the basis of the image.
