摘要： A plurality of detector rings in which detectors arranged densely or spatially in a ring shape or in a polygonal shape are arranged, with an open space kept in the body axis direction, coincidences are measured for some of or all of detector pairs connecting the detector rings apart from the open space to perform three-dimensional image reconstruction, thereby imaging the open space between the detector rings as a tomographic image. Therefore, the open space is secured, with the deteriorated quality of an image suppressed, thus making it possible to easily gain access to a patient under PET scanning from outside a gantry and also provide irradiation of particle beams for cancer treatment as well as X-ray CT scanning.

摘要： In beam monitoring for detecting annihilation radiations produced by radiation irradiation in radiation therapy for cancer which is performed by irradiating the affected area by X-rays, gamma rays, or particle beams, a detector-shift type combined radiation therapy/PET apparatus is provided with an open PET device that includes a plurality of shiftable multi-ring detector rings; and a radiation irradiation device that is capable of irradiation with a radiation beam through between the detector rings. The apparatus changes the positions of the detector rings, performs irradiation with the radiation beam through between the detector rings, and then performs radiation measurement.

摘要： A plurality of CT images of an organ (10) which has undergone a subtle variation or deformation are used as input data, blood vessels and trachea 12 distributed inside the organ are extracted and subjected to thinning, the thus thinned images 14 are used to extract the coordinates of bifurcations 16 and connections, the thus extracted coordinates are used as feature points to track the motion of individual points between a plurality of CT images in a three dimensional space, thereby measuring the movement of the organ (10). Thus, it is possible to realize a local motion tracking at an arbitrary point over an entire region inside an organ, which would be impossible by using a metal marker.
