In a medical imaging system including plural imaging section, detection accuracy and examination efficiency for breast cancer are improved by setting appropriate imaging condition. The system includes: a first imaging section for imaging an object to be inspected by using one of radiation, ultrasonic waves, nuclear magnetic resonance, positron, infrared light and fluorescence to generate a medical image; a second imaging section for imaging the object by using another one of radiation, ultrasonic waves, nuclear magnetic resonance, positron, infrared light and fluorescence to generate a medical image; and an imaging condition setting section for setting imaging condition in the second imaging section based on the medical image generated by the first imaging section.
