ABSTRACT:
A helical scanning operation is performed while a bed is moved, so that data by one-time rotation is collected while positional relationships between a detecting system and a phantom relatively are changed. Further, data obtained by scanning an air region and data obtained by scanning a water region are discriminated on the basis of positional information obtained by positioning scanning or the difference between the air and the water in X-ray absorptance, and correction data is created on the basis of the discrimination.
