Abstract
First and second markers are disposed respectively on the processus xiphoideus and the incisura jugularis of the subject to be inspected. The chest of the subject is positioned below the cryostat so that a line joining the first and second markers extends in one direction in which sensors are arranged in the interior of the cryostat. Processing includes (1) forming, from magnetic waveform signals, an image representing the activity of the heart of the subject, (2) making the pixel size of a morphological image, including the heart photographed by an image pickup device, coincident with the pixel size of functional information and forming a functional image equal in pixel size to the morphological image, (3) making the position of the first marker in the functional image and the position of the first marker in the morphological image coincident, and (4) combining the functional image and the morphological image.
