Abstract: A method of improving energy determination of a Gamma event which interacts with a segmented scintillation detector, the method comprising: identifying radiation events detected by a detector that are likely not to have deposited their full energy in the detector, based only on characteristics of said detected events; and treating the identified radiation events differently from other radiation events that are likely to have deposited their full energy in the detector.

Abstract: A CT scanner comprises a static gantry member and a rotatable member mounted on the gantry member for rotation about a central axis. A stationary power supply is associated with the gantry member for supplying power to an x-ray tube mounted on the rotatable member. An inductive coupling is responsive to the power supply for transmitting electrical power to the x-ray tube from the gantry member. The x-ray tube is operable in response to the transmitted power for producing x-ray beams passing through the central axis.

Abstract: An NMR imaging system includes apparatus for producing a uniform magnetic field in a predetermined volume. Such apparatus includes a ring assembly having an axial extent L defined by a plurality of nonmagnetic rings, each having an axis and positioned side-by-side so that the axes of the rings are colinear and define the axis of the ring assembly. A plurality of discrete permanent magnet segments are angularly mounted within each ring for defining a central coaxial aperture. Each segment in a ring has a easy axis of magnetization whose orientation is functionally related to the angular position of the segment in the ring. Each segment has inner and outer edges that are nominally located at distances r.sub.1 and r.sub.2, respectively, from the axis of the ring from which it is mounted. The inner free ends of the segments of all of the rings define a central aperture of length L within the ring assembly. Finally, an adjustment is provided for moving the segments in each ring such that the distance r.sub.

Abstract: An antenna system for nuclear magnetic resonance (NMR) imaging or spectroscopy devices which produce a uniform magnetic field in an object under examination includes transmit and receive antenna arrays each comprising a group of loop antennas. A signal generating circuit produces a set of input antenna signals which are applied to the loop antennas of the transmit array which transmits RF signals of a frequency that perturbs the magnetic moment of nuclei in a volume of the object. The receiving antenna array is responsive to NMR signals produced by the relaxation of perturbed nuclei in said volume for producing a set of output antenna that are applied to a signal processing circuit. A control circuit selectively controls the relative phases and amplitudes of at least one set of antenna signals to control the size and location of the region of the volume in which excitation of nuclei occurs, or from which NMR signals are processed.
