Patent ID: 8787518

Claim:
A tetrahedron beam computed tomography system comprising: an x-ray source array that sequentially emits a plurality of x-ray beams at different positions along a scanning direction; a collimator that intercepts said plurality of x-ray beams so that a plurality of fan-shaped x-ray beams emanate from said collimator towards an object; a first detector receiving a first set of fan-shaped x-ray beams after they pass through said object, said first detector generating a first imaging signal for each of said received first set of fan-shaped x-ray beams; a second detector receiving a second set of fan-shaped x-ray beams after they pass through said object, said second detector generating a second imaging signal for each of said received second set of fan-shaped x-ray beams; a computer connected to said first detector and said second detector so as to receive 1) said first imaging signals for each of said first set of received fan-shaped x-ray beams and 2) said second imaging signals for each of said second set of received fan-shaped x-ray beams, wherein said x-ray source array, said first detector and said second detector rotate about a rotation axis so as to rotate about said object so that multiple imaging signals are reconstructed by said computer to generate a three-dimensional tetrahedron beam computed tomography image therefrom; and a display connected to said computer and displaying said three-dimensional tetrahedron beam computed tomography image.
