The Optek ™ Demi-Baseplate is specifically designed for the Elekta HexaPOD ™ evo RT System, but is equally useful for situations requiring S-type masks with a shortened baseplate. It is extremely lightweight and gently tapers at the end for patient comfort. The Optek ™ Demi-Baseplate is made of carbon fiber. It is compatible with all standard S-type masks and uses standard silverman pins for headrest indexing. The Optek ™ Demi-Baseplate is dual-configured for adult and pediatric patients.
