Abstract
A calibration phantom is configured to be difficult to deform and easy to handle. The calibration phantom can be used in a case of acquiring calibration data of a photon-counting type detector that outputs an electrical signal corresponding to photon energy of an incident X-ray. The calibration phantom includes first base substances and a second base substance which are known substances, the second base substance having an atomic number larger than an atomic number of the first base substances and being sandwiched between the first base substances.
