To provide a photographing system capable of obtaining the more detailed data related to the auditory ossicle.
An MRI system has a pump 15. The pump 15 has a pressure pump 151a for forming the pressure supplied to the external auditory miatus AC of a subject and the pressure formed by the pressure pump 151a is supplied to a tube. An ear plug 153 is attached to the leading end of the tube and mounted in the external auditory miatus AC in a freely detachable manner. In the case of photographing, the ear plug 153 is mounted in the external auditory miatus AC of the subject and pressure is supplied to the external auditory miatus AC from the pressure pump 151a through the tube while the internal pressure of the external auditory miatus AC is adjusted to three stages of atmospheric pressure, 400 daPa and -400 daPa to photograph an ear EA.
