ABSTRACT:
An apparatus for measuring hardness of a material that makes it possible to measure hardness of a material having high spatial resolution over a wide area, hardness of tissue of a living body, hardness of micro areas in the entire organ and express the flexibility and robustness of the tissue of the living body based on CT values of an X-ray CT scanner. It includes an X-ray scanning section that scans and irradiates a specimen with X-rays, a CT value output section that calculates and outputs a CT value by measuring intensity of X-rays that have passed through the specimen, a storage apparatus that stores the correspondence relationship between CT value data and hardness data of a plurality of reference portions of tissue of the living body, a hardness conversion operation apparatus that converts to hardness using the correspondence relationship and a display that outputs the converted hardness.
