Title: Radiation imaging system

Abstract

A radiation imaging system includes a casing and a camera disposed inside the casing. A first field of view through the casing exposes the camera to light from outside of the casing. An image plate is disposed inside the casing, and a second field of view through the casing to the image plate exposes the image plate to high-energy particles produced by a radioisotope outside of the casing. An optical reflector that is substantially transparent to the high-energy particles produced by the radioisotope is disposed with respect to the camera and the image plate to reflect light to the camera and to allow the high-energy particles produced by the radioisotope to pass through the optical reflector to the image plate.

  • A method for imaging a radiation source, and a device that utilizes these methods that in one embodiment include the steps of: calculating at least one Compton cone of a first parameter of a radiation emission from information received from a sensor occurrence; and tracing this Compton cone on to a unit sphere having preselected characteristics using an estimated angular uncertainty to limit at least a portion of said tracing. In another embodiment of the invention at least two Compton cones are calculated and then intersected upon a predefined surface such as a sphere. These intersection points can then bemore » iterated over a preselected series of prior events.« less

  • A radiation imaging system employs a super-heated, super-conducting colloid detector subjected to an external magnetic field such that all the colloid grains are maintained in the metastable super-conducting state in the absence of radiation. Imbedded in the detector are intersecting helical sensing coils that divide the detector into volumetric resolution elements. The grains in each element that absorb x-ray or gamma ray photons emanating from an object make a transition to the normal conducting state thereby producing flux changes in the vicinities of the grains which induce signals in the coils defining the resolution element in which those grains aremore » located. The number of signals from each element is accumulated separately and used to produce an image of the object. 10 claims.« less
  • A nuclear imaging system is described for mapping a spatially distributed source of high energy nuclear particles from a living organ which has selectively absorbed a radioactive compound in which the nuclear energy is spatially coded by a zone plate positioned between the source and a spatial detector, and a half tone screen is positioned between the source and the zone plate to increase the definition of the image.
