Abstract:
1. A computed tomography system comprising: (a) a housing assembly defining a tubular cavity about a perpendicular axis; (b) a tubular outer hoop assembly mounted within the housing about the perpendicular axis; (c) a tubular inner hoop assembly supporting a plurality of spaced apart x-ray photostimulable detector members, the inner hoop assembly rotatably coupled to the housing about the perpendicular axis and inside the outer hoop assembly; (d) an x-ray source adapted to expose an object within the tubular cavity with x-ray energy, the x-ray source moveably coupled to the outer hoop assembly and adapted to move about a common arc with the outer hoop assembly and expose objects located within the tubular cavity; (e) a computed radiography device mounted within the housing between the inner hoop assembly and the outer hoop assembly and adapted for scanning at least one of the x-ray detector members and for acquiring x-ray energy from the detector members and wherein said computer radiography device utilizes a scan head for such scanning; (f) a first drive apparatus adapted for rotating the detector means about the tubular cavity relative to the radiography device; (g) a second drive apparatus adapted for moving the x-ray source along the common arc about the tubular cavity; (h) wherein the inner hoop and x-ray source are independently rotatable about the tubular cavity to expose the object with x-rays from a plurality of perspectives; and (i) wherein when the inner hoop assembly is rotated relative to the housing, the detector members are rotated relative to and adjacent the radiography device allowing the radiography device to acquire any retained x-ray exposure energy from the adjacent detector member.
