Proton Therapy Solutions

Proton Positioning and Immobilization

Let us introduce to you how Orfit patient positioning and immobilization for proton therapy can help you with achieving accurate daily positioning, minimal patient motion and increased patient satisfaction.

Aerial®, an entirely new proton couch top that optimizes the impact of the proton dose. Combined with Nanor® masks we bring more comfort to the patient while safeguarding  stability and reproducibility.

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 Aerial Couch Top consists of a base and a variety of extensions (available in different lengths)

• No rails or other parts underneath the extension that obstruct the beam
• Homogeneous over the entire treatment area
• Radiolucent
• Multiple indexing points for easy positioning reproducibility

This carbon fibre BASE PLATE is the basic element of the ORFIT HP PRO SOLUTION. It is used in combination with special 3 and 5 point HP PRO masks, a cranial stop and a personalised head rest to form a reproducible patient positioning and immobilisation device.

Positioning solutions Accessories

Hand Holds

Hand holds offer your patient a place to rest their hands during treatment. It will help them feel more relaxed during treatment and has a positive effect on tense shoulders. 

T-shaped Vacuum Bag and Moldcare Cushion

A vacuum bag or moldcare cushion gives extra support to your patient’s shoulders. Individual shoulder positioning will prevent shoulder sagging.

Head & Neck Moldcare Cushions

Available in three sizes to create a personalized head rest cushion.

Flexible Shim

A flexible shim is placed on top of the moldcare head rest cushion to counteract patient swelling.

Head Rest Indexing Plate

The Head Rest Indexing Plate is used to attach a personalized head support, such as a Moldcare Cushion, to the base plate.

Cranial back stop

To ensure that the head of the patient is correctly positioned, and prior to the molding of the mask, a cranial back stop can be attached to the cup-like head rest  of the base plate.

Orfit masks for proton therapy are available for brain; head, neck and shoulders; and abdomen-pelvis.

All cranial mask profiles are designed without sharp corners or edges to achieve an optimal interaction between the immobilization equipment and the proton beam. The patented mask locking mechanism clicks on the base plate in two steps and can be quickly released in case of emergency. The masks contribute to minimal patient motion, and maximum comfort by using Nanor thermoplastic materials.

Abdomen-pelvic masks are used for patient immobilization for extracranial proton treatments, and are easily attached to the base plate with push-pins.

A high comfort level may promote patient stability and will contribute to the best possible patient experience, but finding a comfortable treatment position for your patient continues to be a challenge? Conventional immobilization solutions have limitations regarding patient comfort and some clinicians naturally hold on to the most rigid materials available in the market. 

To better understand, let’s dive into a conventional thermoplastic mask. Its internal structure consists of a non-exfoliated polymer matrix, where polymer layers are completely separated. Once the mask has cooled down to room temperature, these polymer layers will shrink, creating a mask that feels too tight and that brings physical discomfort. Nanor masks, that consist of a polymer matrix reinforced with nanoparticles, form a cluster network that keeps the micro volume sizes more stable. It results in a mask with less shrinkage and less pressure on the patient’s face. These same nanoparticles establish a unique internal structure that create a very strong mask with a thickness of only 1.6 mm.

With Nanor we focus on the impact a mask can have on a positive patient experience. It’s about how your patients feel. Do they feel calm? Are they able to control their breathing? Does he or she feel fine lying immobilized on the treatment couch? Optimizing patient experience during simulation and treatment plays an important role in achieving a better overall experience, with better care as the final outcome.
