Provided is a data collection method wherein intensity distribution image of near-infrared fluorescence obtained by irradiating an organ of a living body to be tested to which indocyanine green is administered with excitation light of indocyanine green is compared with a cancer lesion distribution image obtained by making X-rays, nuclear magnetic resonance or an ultrasonic wave act on the organ to be tested before indocyanine green is administered, and the data in a region which is detected in the intensity distribution image of near-infrared fluorescence but not detected in the cancer lesion distribution image is collected as the data of a sub-lesion region of cancer. |
