ABSTRACT:
An improved immobilization device (10) for specific patients and body parts is provided which insures that a body part is immobilized and can be successively repositioned in the same location during successive treatments. The device (10) is thus particularly applicable for treatment such as radiation therapy where it is important to properly focus treating radiation on a particular locale from treatment-to-treatment. The device (10) preferably includes a frame assembly (16) adapted to rest upon a surface and which supports a preformed, shape-retaining material (12) presenting a concavity (14) substantially conforming with a selected body part to be immobilized. The device (10) when used for head immobilization, may also be provided with stabilizer (98) in the form of an adjustably positioned bite block (134). Hold-down straps (52, 54) can also be employed for further immobilization. Additional immobilization may also be provided by a nose bridge holddown assembly (136) operably coupled to frame assembly (16) and engaging nose bridge and eyebrow region of the patient.
