AERIAL - CouchTop for Proton Therapy


The Aerial Couch Top combines precise and reproducible immobilization with homogeneity over the entire treatment area. With no rails or other obstructions below the extension, this recently US FDA cleared couch top minimizes the air gap, improving penumbra and plan quality.

Aerial extensions are available for extracranial treatment and brain, head, and neck treatments when used with Orfit HP PRO masks. The use of 3-points single layer HP PRO masks can reduce target margins to 1 mm.

Changes in WET Value in the couch top are limited to less than 0.5 mm WET variation over a 10 cm distance in longitudinal direction.

“The design of the Aerial is in line with the highest technical and safety standards, without being overly complex, so that it helps assure the best possible clinical outcome for patients. This couch top perfectly pairs with advanced proton therapy systems, such as MEVION S250i,” states Emilie Cuypers, product manager radiation oncology at Orfit.

Orfit Industries Receives 510(k) FDA Clearance for the Aerial® Proton Couch Top System

NORFOLK, Va., May 15, 2020 /PRNewswire-PRWeb/ -- Orfit today announced it has received FDA 510(k) clearance for its Aerial® Couch Top for Proton Therapy.

Aerial® is an entirely new couch top that optimizes the positioning and immobilization of cancer patients during proton therapy treatment. A homogeneous treatment area is provided by eliminating all rails or other obstructions underneath the couch top. The smooth shape transitions, minimal sharp corners in the treatment area and thin design characterize the couch top. All of this while supporting a patient load up to 235 kg.

To immobilize patient's with a brain tumor or a tumor in the head and neck region, Orfit HP PRO masks help to attain the high level of reproducibility and precision that proton therapy demands. The 3-points single layer HP PRO mask allows for a planning target volume margin of 1 mm which decreases the risk of damage to healthy tissue.

"By prototyping, testing, analyzing and close cooperation with physicists and therapists, we created a couch top that is in line with the highest technical standards, without being too complex. The combination of these factors will help in assuring the best possible clinical outcome for patients", says Emilie Cuypers, Product Manager Radiation Oncology.

Orfit Industries is proud to bring a couch top on the market that perfectly pairs with advanced proton therapy delivery techniques.
