Splitting the SOBP into three beams so as to further reduce the RBE effect. This what is typically done when a single beam plan is being used such as with a posterior fossa boost or germinoma boost after whole ventricular radiation is employed. It can be employed at other times as well when there is significant clinical concern regarding a specific organ at risk.
