Abstract: An image processing apparatus according to an embodiment includes a processing circuitry. The processing circuitry is configured to acquires an image by capturing a subject laid on a table of a magnetic-resonance imaging apparatus with a camera, detects a loop having a possibility of generating an induced current by a magnetic field that is generated by the magnetic-resonance imaging apparatus from the image, and outputs a detection result.

Abstract: A magnetic resonance imaging apparatus according to an embodiment includes a gantry, a first illuminating unit, and processing circuitry. The gantry has a hollow bore. The first illuminating unit illuminates the hollow bore. The processing circuitry identifies the position of a predetermined region of the subject inside the hollow bore, and controls the illumination state of the first illuminating unit based on the identified position of the predetermined region.
