Posicast thermoplastic material has been specifically developed for radiotherapy applications and provides excellent positioning and reproducibility during treatment. It does not stick to the skin or hair. If needed, Posicast adheres to itself by applying local pressure. The patented composition of this unique product results in minimal shrinkage after cooling.

Posicast thermoplastic materials are available in Multiperfo and Microperfo versions depending on the selected material. Microperfo masks are preferred when small sized treatment fields are to be marked onto the mask.

Posicast

Posicast has a soft polyurethane coating on both sides guaranteeing ultimate comfort in handling. It is available in Multiperfo and Microperfo.

Posicast-Plus

Posicast-Plus has two different coatings: a soft polyurethane coating on the side which is in direct contact with the patient’s skin and a smooth spray-coating on the outside where treatment fields are to be marked directly onto the mask. Posicast-Plus material is comfortable to the skin and offers the possibility of precise field marking. Minimal shrinkage of the material ensures rigid and reproducible fixation. Posicast-Plus is only available in Microperfo material.

Posicast-Lite

With a smooth spray coating on both sides, Posicast-Lite feels like a traditional thermoplastic. However, its polycaprolactone core ensures a rigid and reliable fixation. Posicast-Lite is available in Multiperfo and Microperfo.

Precuts

CIVCO offers a wide variety of thermoplastic precuts. Rectangular plates are available allowing technologists to cut the material in any desired shape. All types are sold in sets of 10 pieces. The materials have a thickness of 2.3mm. Precuts are available with reloadable or disposable L-profile mask attachment handles.

L-profiles for Mask Attachment

By using radiotransparent L-profiles fitted with durable quick fasteners, a rigid mask can be molded around the contours of the patient. With this method air gaps between the inside of the mask and the head of the patient are prevented, resulting in a very reliable, stable mask.

Reusable Carbon Fiber L-profiles are attached to the
desired precut before making a mask and remain on for
the duration of treatment. Disposable L-profiles come attached to a mask and are a quick, cost effective alternative to reusable carbon fiber L-profiles.
