CBCT image workflow for transarterial chemoembolization; dual-phase CBCT, with arterial and venous phase acquired from the C-arm spinning back and forth or twice around the patient. (A) The lesions are segmented from the venous phase. (B) The arterial supply to the segmented lesions is extracted from the arterial CBCT. This process may be semiautomated or manual. A virtual path is mapped from the catheter position to the desired vessels. (C and D) The vascular map and virtual path are overlaid on the live fluoroscopy. The image may be adjusted to account for magnification, or table or C-arm movement. (Color version of figure is available online.)
