ConclusionPreliminary image quality tests of a prototype MV-CBCT imaging system that utilizes a 6X-FFF beam and a fast acquisition mode revealed acceptable performance, but as expected, worse than those of kV-CBCT and diagnostic CT.The fast acquisition may potentially be beneficial for motion management treatments such as DIBH for breast and lung tumors.The MV-CBCT also has superior contrast linearity for higher density and metallic materials because of reduced beam hardening, and could be utilized to supplement diagnostic CT images for treatment planning in such cases.
