The time for obtaining ultrasonic images can be reduced by using a two-dimensional transducer array and good radiation images can be obtained even when radiation imaging is performed with the fixed array. The medical imaging apparatus includes a radiation generating unit for generation radiation, a radiation detecting unit for detecting radiation, an ultrasonic transducer array provided between the radiation generating unit and the radiation detecting unit and including two-dimensionally arranged ultrasonic transducers, a radiation image data generating unit for generating radiation image data based on a detection result of the radiation detecting unit, and an image processing unit for performing image processing on the radiation image data generated based on a detection result of radiation transmitted through an object to be inspected and the ultrasonic transducer array, thereby removing an image of the ultrasonic transducer array from a radiation image represented by the radiation image data.
