PROBLEM TO BE SOLVED: To provide a medical imaging apparatus for imaging mammary gland and breast while compressing the breast with a compression plate, in which the influence of reflection and attenuation of ultrasonic waves in the compression plate can be reduced to improve the image quality of ultrasonic images. SOLUTION: The medical imaging apparatus includes: an imaging stage on which an object to be inspected is mounted; a compression plate compressing the object between the imaging stage and itself; an ultrasonic probe provided to maintain acoustic connection with the compression plate, for transmitting ultrasonic waves according to drive signals and receiving ultrasonic echoes generated when the transmitted ultrasonic waves are reflected by the object to output reception signals; an ultrasonic imaging unit for supplying the drive signals to the ultrasonic probe and generating image data based on the reception signals outputted from the ultrasonic probe; and a control unit for controlling the ultrasonic imaging unit according to information based on a material and/or a thickness of the compression plate to adjust levels of the drive signals to be supplied to the ultrasonic probe.
