Abstract

1,258,902. Radiation detector matrix. ELECTRONIC & X-RAY APPLICATIONS Ltd. March 4, 1969 [March 5, 1968], No.10507/68. Heading G1A. A matrix of radiation detectors is carried in a support comprising a hexagonal cylinder 2 of stainless steel retaining a plurality of hollow aluminium tubes 1. The gaps between the tubes are filled with potting compound and as many detectors as required are inserted in the tubes 1. The type of detector used may be a thalliumactivated sodium iodide metal 13 coupled to a photo-multiplier 14. Alternatively, geiger counters may be used. The end of each tube contains a lead insert 12 acting as a collumator. Lead sheeting is also provided inside the steel outer core 2 to provide screening. The detector apparatus may be adjustable in position and has application in monitary blood flow in the brain of a patient who has been injected with or has inhaled a radioactive isotope.
