    摘要： The extraction processor of the medical image-processing apparatus sets landmarks of each medical image based on volume data of two medical images. The positional relationship information-generating part generates positional relationship information that indicates positional relationship of the landmarks for each of the two medial images. The landmark-coordinating part eliminates one or more landmarks from each medical image based on the positional relationship information. Further, the landmark-coordinating part coordinates the landmarks of two medical images that remained after the elimination. The image-aligning part aligns the two sets of volume data based on the result of the coordination of landmarks.

    摘要： A detector (301) having a collimator (303) 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 (301) 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.
