Abstract: A detector having a collimator in a position at a specific angle with respect to a therapeutic X-ray beam is mounted to selectively detect only scattering radiation in the direction. To three-dimensionally obtain a distribution of places where scattering occurs in a patient body, a detector is rotated during irradiation and scattering radiation is measured from all of directions. After that, a reconstructing process is performed, and a distribution of occurrence of scattering radiation in the subject is three-dimensionally imaged. Since angles and amounts of X-rays scattered by Compton scattering are known theoretically, if scattering radiation at a certain angle can be detected, the number of scattering radiation at other angles can be also estimated. On the basis of the theory, images of distribution of scattering radiation sources are converted to images of distribution of absorption of radiation.

Abstract: An FPD has a detecting plane with detecting elements arranged in rows (u-axis) and columns (v-axis) extending in two intersecting axial directions. In time of primary scanning, the FPD is moved about a sectional axis to maintain the u-axis parallel to a body axis constantly. Consequently, in a reconstruction process, a set of projection points on the detecting plane of X rays having passed through lattice points in one row along the body axis A of an imaginary three-dimensional lattice, is parallel to the u-axis. It is therefore possible to derive all projection data that should be projected back to the lattice points in one row, only from detection signals acquired from the detecting elements in two lines having the set of projection points in between. Thus, the quantity of detection signals required for obtaining the projection data is reduced to perform the reconstruction process at high speed.

As a result, it is possible to maintain a specific ratio between the heart rate of the examined patient and the rotational speed even if the heart rate of the patient changes during the examination.
