Abstract
An X-ray tomography scanner and an optical tomography scanner are combined to obtain an optical image indicting metabolism in the body. Optical projection data indicating light pulse transmissions in the body are compensated by using a light scattering coefficient distribution determined by an X-ray tomogram image discriminated into individual internal organs or tissues. The compensated projection are back-projected.
