Radiation imaging system
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 are located. The number of signals from each element is accumulated separately and used to produce an image of the object. 10 claims.
