Abstract
Abstract An apparatus for isotope diagnosis to determine the distribution of radioactive substances in a body. The apparatus incorporates two radiation detectors connected for synchronous scanning of an examination zone of the body, one of the detectors being mounted in an accessory accessary which is adapted for connection to the housing of the other detector.

An apparatus for isotope diagnosis to determine the distribution of radioactive substances in a body, said apparatus comprising: a. a first housing; b. a first radiation detector defining a radiation entry aperture and mounted on said first housing for a scanning movement longitudinally and transversely of said first housing; c. drive means in said first housing for effecting said scanning movement; d. a diagnostic table mounted on said first housing; e. means for moving said table towards and away from said first detector perpendicularly to the plane of detector movement; f. a second housing adapted to be connected to said first housing and to be slid beneath said table; g. a second radiation detector defining a second radiation entry aperture and mounted on said second housing for a scanning movement identical to that of said first detector and on a side of said table opposite to that of the first detector, said second detector having a sensing finger projecting beyond its radiation entry aperture; h. means connected with said second detector for raising and lowering said second detector relatively to said second housing; and i. second drive means on said second housing for effecting the scanning movement of said second detector, said sensing finger of the second detector being connected to said means for raising and lowering said second detector and to said means for moving said table, whereby the movements of said second detector are coupled with the movements of said table, said second drive means being electrically connected with said first drive means for a control simultaneously and synchronously with said first drive means such that the radiation entry apertures in said detectors align.
