Title: Flexible nuclear medicine camera and method of using

Abstract

A nuclear medicine camera 10 and method of use photographically record radioactive decay particles emitted from a source, for example a small, previously undetectable breast cancer, inside a patient. The camera 10 includes a flexible frame 20 containing a window 22, a photographic film 24, and a scintillation screen 26, with or without a gamma-ray collimator 34. The frame 20 flexes for following the contour of the examination site on the patient, with the window 22 being disposed in substantially abutting contact with the skin of the patient for reducing the distance between the film 24 and the radiation source inside the patient. The frame 20 is removably affixed to the patient at the examination site for allowing the patient mobility to wear the frame 20 for a predetermined exposure time period. The exposure time may be several days for obtaining early qualitative detection of small malignant neoplasms.

  • A nuclear medicine camera and method of use photographically record radioactive decay particles emitted from a source, for example a small, previously undetectable breast cancer, inside a patient. The camera includes a flexible frame containing a window, a photographic film, and a scintillation screen, with or without a gamma-ray collimator. The frame flexes for following the contour of the examination site on the patient, with the window being disposed in substantially abutting contact with the skin of the patient for reducing the distance between the film and the radiation source inside the patient. The frame is removably affixed to themore » patient at the examination site for allowing the patient mobility to wear the frame for a predetermined exposure time period.

  • An improved gamma camera arrangement is described wherein the spatially defined acceptance of gamma radiation from a source distribution of clinical interest is enhanced by a unique collimator structure. Aliasing frequencies otherwise derived from an orthogonal strip detector array are identified and avoided through a structural geometry wherein collimator resolution is greater than or equal to about 1.7(l), where, l, is the strip spacing of the array.
  • This invention relates to a flexible printed circuit board that is used in connection with an optical transmitter, receiver or transceiver module. In one embodiment, the flexible printed circuit board has flexible metal layers in between flexible insulating layers, and the circuit board comprises: (1) a main body region orientated in a first direction having at least one electrical or optoelectronic device; (2) a plurality of electrical contact pads integrated into the main body region, where the electrical contact pads function to connect the flexible printed circuit board to an external environment; (3) a buckle region extending from one endmore » of the main body region; and (4) a head region extending from one end of the buckle region, and where the head region is orientated so that it is at an angle relative to the direction of the main body region. The electrical contact pads may be ball grid arrays, solder balls or land-grid arrays, and they function to connect the circuit board to an external environment. A driver or amplifier chip may be adapted to the head region of the flexible printed circuit board. In another embodiment, a heat spreader passes along a surface of the head region of the flexible printed circuit board, and a window is formed in the head region of the flexible printed circuit board. Optoelectronic devices are adapted to the head spreader in such a manner that they are accessible through the window in the flexible printed circuit board.« less
  • After drilling an earth borehole, the drill pipe and drill bit are removed from the borehole and the drill pipe is reinserted into the borehole. A flexible hose such as a fire hose, has a retro-nozzle at its lower end, is then pumped down through the interior of the drill pipe and a portion of the hose is pumped out through the end of the drill pipe for a desired distance. A well logging instrument is pumped through the flexible hose which extends down past the bottom of the drill pipe and well logging operations are performed through the flexiblemore » hose. In very hot wells, the drilling mud or other circulating fluid can continue to be pumped through the flexible hose to provide cooling of the well logging instrument.« less
  • A map of a radiation field produced by a gamma camera is corrected for three types of spatially dependent errors in a manner that corrects for each error independently of the others. The errors corrected for are dislocations which result from the non-linearity of the optics, photomultipliers and electronics of the camera, energy window variations resulting from inhomogeneity of the optical system which includes the crystal, light guide, and photomultipliers, and the non-uniform sensitivity of the head resulting from the non-uniform stopping power of the crystal and collimator of the camera head. The map is corrected by obtaining a setmore » of correction factors associated with each type of error using a calibration technique that insures independence between the various correction factors, and applying the correction factors to the map obtained in a nuclear imaging process in a way that independently corrects the map for each type of error.« less
