Mevion Industry Symposium:Application of MLC-based IMPT in Complex Clinical Cases

In IMPT-based proton therapy, spot size and lateral penumbra are critical to precisely deliver treatment and spare critical structures close to the target. Using Mevion’s HYPERSCAN PBS with Adaptive Aperture proton MLC, an optimal spot size and sharper penumbra can be achieved at each energy layer of the target, thus creating a more conformal treatment field than previously achievable by relying on small spot sizes alone.

In July, users who have successfully deployed Mevion’s Adaptive Aperture proton MLC in their clinical programs presented at Mevion Industry Symposium at NAPT 2020. The speakers shared the advantages they have experienced and how MLC-enhanced IMPT may further advance the treatment paradigm of proton therapy over IMRT through improved proton dose conformality.
