A medical imaging apparatus comprises a respiration depth detecting device for detecting a respiration depth of a subject and an indication device for indicating the respiration depth determined by the respiration depth detecting device to the subject. The respiration depth detecting device includes a measuring device for measuring a position of the surface of the body of the subject, a device for detecting a maximum value and a minimum value of the respiration depth of the subject on the basis of maximum extreme values and minimum extreme values of the position of the surface of the body measured by the measuring device, and a device for calculating the respiration depth of the subject on the basis of the position of the surface of the body measured by the measuring device and the maximum value and minimum value of the respiration depth. The indication means includes a plurality of light emitting elements, and a device for turning on at least one of the light emitting elements in accordance with the respiration depth of the subject.
