Abstract 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.
An apparatus for acquiring a medical image of a subject, comprising: respiration depth detecting means for detecting a respiration depth of the subject; indication means for indicating the respiration depth detected by said respiration depth detecting means to the subject; image acquiring means for acquiring a predetermined image of the subject only during a time when the subject holds its breath in accordance with the indicated respiration depth by the indication means; storage means for storing the respiration depth of the subject; and read means for reading out the respiration depth of the subject from the storage means.
