摘要： Embodiments of the present invention may provide a PET-MRI hybrid system capable of arranging a PET apparatus and an MRI apparatus in a line. An MRI room containing the MRI apparatus and a PET room containing the PET apparatus are provided at either side of a central waiting room as opposed to each other about the waiting room. A rail portion linearly extends from the PET room to the waiting room on their bottoms. Another rail portion linearly extends on the bottom of the MRI room. A transfer unit, which supports a subject lying thereon, travels along the rail portions of the waiting room, the MRI room and the PET room. A bridge unit is provided between the rail portion of the waiting room and the rail portion of the MRI room. The bridge unit provides a space for opening and closing a shield door of the MRI room and allows the transfer unit to be reciprocated between the waiting room and the MRI room by selectively connecting the rail portion of the waiting room and the rail portion of the MRI room.

摘要： A method and apparatus are provided for reconstructing 3D image. The method may include the steps of: detecting a plurality of line of responses (LORs) emitted from an object; transforming the plurality of LORs into first sinogram data; back-projecting the first sinogram data with a plurality of projection angles to produce image data for the object; and projecting the produced image data with the plurality of projection angles to transform the image data into second sinogram data. The back-projecting may include filling pixels of image plane for each of the plurality of projection angles with the first sinogram data and rotating a coordinate axis of the image plane with corresponding projection angle to produce the image data. The projecting may include rotating the image data with corresponding projection angle in an opposite direction before projecting the image data with the plurality of projection angles. The projecting and the back-projecting may use symmetry properties in coordinate space.

摘要： There is provided a PET-MRI hybrid apparatus and method for integrating a PET image and an MRI image so that anatomical, hemodynamical and molecular information on human tissues are simultaneously presented in a single image. The PET-MRI hybrid system comprises a first scanner for obtaining anatomical and hemodynamical information, and a second scanner for obtaining molecular and functional information on the human tissues. Along a path between the first scanner and the second scanner, a transferring railway system which includes runs, and a movable bed for supporting a subject installed on the railway. The PET-MRI hybrid system also comprises a “RF+magnetic” shield and a “magnetic” shield between path between the first scanner and the second scanner, which switch between an open status and a close status in a completely synchronized manner to assure a complete magnetic shield for the PET system at any given time. The subject is fastened on the bed and transferred along the railway between the first and second scanner to provide accurately fused MRI and PET images.
