Abstract: This disclosure relates generally to CT x-ray imaging systems and methods, and particularly to an inverse geometry with tetrahedron beams. Specifically, a dose efficient and controllable inverse geometry tetrahedron beam CT imaging is disclosed. The disclosed CT geometry includes a linear array of x-ray sources perpendicular to a rotation axis of the CT system and rotates together with a linear detector array extended parallel to the rotation axis.

The intensity of each beam is dynamically adjusted and controlled during the rotation of the source array and the detector array. Such a configuration provides control of x-ray intensity over a selected region of interest in a target object during the rotation even if the region of interest is off from the rotation axis, with efficient dose control.
