Introduction: Cone beam computer tomography (CBCT) suffers inferior image quality due to scatter and other problems. We are developing a novel tetrahedron beam computed tomography (TBCT) imaging system which consists of a linear scan x-ray source and a linear x-ray detector array. TBCT system avoids the inherent problems of CBCT, thereby can significantly improve the quality of online images in image guided radiation treatment. In this paper, we describe the development of a TBCT benchtop system.
