  • Publication number: 20150320372
    Abstract: A radiation imaging apparatus includes: a beam splitter; a detector that detects radiation passing through the beam splitter and the object; and a processing device that generates image data representing information on an inside of the object on the basis of data obtained with the detector. A first distance which is a distance between the beam splitter and the object can be changed. The processing device has a determination unit that determines the first distance that is to be set when the object is imaged, such that a value of the information on the inside of the object falls within a dynamic range of the image data.
