An intraoral positioning device (IPD) is disclosed for positioning in a patient's mouth for radiation therapy planning and treatment, the device comprising an engagement member configured to engage structure within a patient's mouth during radiation planning or treatment, wherein the engagement member includes an upper wall, a lower wall and first and second side walls extending from and between the upper and lower walls, whereby the upper, lower and first and second side walls form top, bottom, front and rear walls of a bite block, and a handle extending from the engagement member to enable a user to grasp the IPD for introducing and removing it from the patient's mouth.
A method and apparatuses are disclosed for registration of the patient's head and oral cavity for radiation therapy treatment of head and neck cancer. The method and apparatuses comprise an intraoral positioning device (IPD) positioned in a patients mouth. The IPD incorporates fiducials embedded in or on an IPD. The fiducials function as markers for tracking and radiation beam direction. These fiducials may be incorporated manually, using 3D printers, or a combination of both. The fiducials allow better registration of the radiation therapy during treatment and from treatment to treatment, and also allows adaptive adjustment during radiation therapy to minimize the effects of patient movement.
