Sinmed Posifix head and neck positioning system is composed of several items.
One can choose from four different baseplates, varying from a basic acrylic head baseplate to a more sophisticated T-shaped carbon fiber baseplate that accomodates a wide variety of head, neck and shoulder masks. A range of head supports, made of low density polyethylene foam, is available for comfortable and consistent prone and supine positioning. Each head support fits snugly into any of the Posifix baseplates and dedicated pediatric cushions are also available.

Positilt, attached to the Posifix baseplate
A highly recommended option is the Positilt, which allows the head to be tilted in various angles towards the couchtop plane and can be easily attached to all Posifix baseplates.
|
The Positilt is a tilt board, the core of which is made of low density foam covered with ultra-thin layers of carbon fiber. This construction assures negligible beam attenuation. In use, the Positilt enables the head to be positioned at angles of 5, 10, 15, 20, 25 and 30 degrees towards the couchtop plane. The Positilt is compatible with and easily attached to all Posifix baseplates for head and neck fixation. |
