Abstract
Obtaining an X-ray CT image of a biological sample includes a step of penetrating a contrast agent into the biological sample and solidifying the contrast agent to provide a contrast image of the biological sample, the contrast agent comprising wax and having a density of 0.95 g/cmor less in its solidified state after penetration into the biological sample, and having a melting point of 40° C. to 80° C., a step of melting and resolidifying the solidified contrast agent, and a step of acquiring an X-ray CT image by irradiating the resolidified biological sample with an X ray having an energy of 4 to 12 keV, the shape of the biological sample being a shape with which a maximum optical path length of the X ray in the biological sample in the step of acquiring an X-ray CT image is 2 mm or less.
