1. A high-energy x-ray imaging system comprising:
a stationary gantry;
a conveyor assembly configured to convey an object to be imaged through said gantry;
a first plurality of linear accelerators arranged in a first arcuate array within said gantry, the first arcuate array spanning a first arc within a first plane, said first array of linear accelerators configured to generate a first respective plurality of high-energy x-ray fan beams to be transmitted through the object;
a second plurality of linear accelerators arranged in a second arcuate array spanning a second arc in a second plane parallel to the first plane, said second array of linear accelerators configured to generate a second respective plurality of high-energy x-ray fan beams to be transmitted through the object;
a first detector array positioned opposite said first array of linear accelerators and positioned within the first plane, said first detector array configured to collect the first plurality of high-energy x-ray fan beams transmitted through the object;
a second detector array positioned opposite said second array of linear accelerators and positioned within the second plane, said second detector array configured to collect the second plurality of high-energy x-ray fan beams transmitted through the object; and
a control system configured to:
energize said first and second arrays of linear accelerators according to a predetermined control sequence to generate the respective first and second plurality of high-energy x-ray fan beams; and
reconstruct a 3-D image of the object based on data received from said first and second detector array and representative of the received first and second plurality of high-energy x-ray fan beams transmitted through the object.
