What is the purpose of CBCT imaging in the Radiant workflow?

CBCT imaging in the Radiant workflow is used for image-guided verification of patient setup before each treatment fraction. It provides a 3D view of the patient’s current anatomy in the treatment position, allowing clinicians to compare it with the planning data and determine any necessary couch shifts or alignments. This ensures the radiation beam is accurately aimed at the target while sparing surrounding tissues, even if the patient’s position shifts slightly between sessions. It is not used to measure the dose delivered after treatment, which is a dosimetry task. It also does not capture motion during the actual treatment in the same way that real-time or cine imaging would. And while planning CT establishes the initial 3D model for treatment, CBCT’s primary role in the routine Radiant workflow is verification and correction of positioning before delivering each fraction.
