The image acquisition system performs multiple 2D rotational acquisitions around the patient with movements in the same or opposite directions in the patient's transverse plane. A single volume is reconstructed from the acquired data (e.g., through "back-projection" algorithm). The reconstruction can either occur on the same system (e.g., Acquisition Modality) or a secondary processing system (e.g., Co-Workstation).

The reconstructed Volume needs to be encoded and saved for further use.
