Abstract
A positron emission tomography apparatus according to an embodiment includes a plurality of positron emission tomography (PET) detector entities and processing circuitry. The plurality of PET detector entities are arranged in a ring formation. The processing circuitry is configured: to obtain, with respect to each of the plurality of PET detector entities, state information indicating a state of the PET detector entity; to detect an abnormality when an index value indicating a state of any individual or a whole of the plurality of PET detector entities exceeds a threshold value on the basis of the state information; and to detect a state in which the abnormality is not detected on the basis of the state information, but an index value indicating states of at least two of the plurality of PET detector entities is different from an index value indicating states of at least two other PET detector entities.
