    摘要： In an open PET device including a plurality of detector rings that are arranged apart in the direction of the body axis of a subject and having a physical open field of view area, at least one of the detector rings or another imaging device arranged in parallel is configured to be movable by simple device moving means in order to change the configuration of the PET device. This improves the versatility of the open PET device for easier introduction to facilities.

    摘要： A three-dimensional position-sensitive radiation detector is provided which has a three-dimensional array of photodetectors disposed on the surface of a scintillator block and which is capable of three-dimensionally identifying the position of light emission at which radiation has been detected within the detector. The three-dimensional position-sensitive radiation detector includes: a scintillator block including a central portion which restricts the direction of diffusion of light so as to direct the light in three axial directions and which has an optically discontinuous region, and an outer portion which is disposed on the outside of the central portion and which does not restrict the direction of diffusion of light; and photodetectors disposed on at least two outer circumferential surfaces of the scintillator block. The detector identifies three-dimensionally the position of light emission, thereby preventing deterioration in position discrimination performance even when inner scintillator elements are smaller than the photodetectors.

    摘要： A blood collecting apparatus includes a cleaning solution piping. The cleaning solution piping feeds into a flow path a heparin solution which is a liquid other than blood to be measured, in order to return the blood present in the flow path to a catheter disposed upstream of a blood inlet of the flow path. Thus, the blood having flowed into the flow path in an amount more than is necessary for blood collection, which corresponds to a portion returned to the upstream catheter of the blood to be measured present in the flow path, can be used in a next blood collection. As a result, the amount of collected blood can be reduced. The liquid to be measured is separated apart by means of a gas, and the flow path is cleaned in a way to leave no impurities in the flow path, thereby preventing impurities from mixing into the liquid to be measured.

    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.
