AI Technical Summary

Benefits of technology

Simplifies the patient setup process, reduces setup time, and enhances treatment accuracy by eliminating the need for cumbersome clamping mechanisms and reducing the number of technologists required for setup.

Problems solved by technology

This allows the frame to be locked down onto the patient restraint device directly and easily, eliminating the need for cumbersome clamping mechanisms which can prolong set-up times, frustrate techs, and may lead to treatment inaccuracy as the lock down mechanisms wear and shift with time and use.
No other current disposable low-melt thermoplastic frames incorporate such a mechanism into its construction.

Embodiment Construction

[0022] It is to be understood that the specific devices and processes illustrated in the attached drawings and described in the following description are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein should not be considered as limiting, unless the claims expressly state otherwise.

[0023] The invention relates to a thermoplastic mask system comprised of a sheet of die-cut low-melt thermoplastic bonded or glued or otherwise secured to a rigid, non-thermoplastic frame, usually in a U-shape or other configuration. The low-melt thermoplastic material has specific properties; i.e., when it reaches a specific temperature the thermoplastic softens and becomes extremely pliable, allowing the material to be stretched over a patient's head or other body part, conforming tightly to the patient's anatomy. As it cools, the thermoplastic becomes rigid...

Abstract

A disposable mask system for positioning a patient relative to a patient restraint board during radiation therapy includes a piece of low-melt thermoplastic material affixed to a rigid, non-thermoplastic frame. A lock-down mechanism is integrally incorporated into the rigid, non-thermoplastic frame, such that a manipulable portion of the lock-down mechanism extends upward from the surface of the rigid frame so that it is accessible by the user. An engagement member extends downward from the underside of the rigid frame such that it can engage corresponding holes in a patient restraint board, such that when the rigid frame is pushed down so that its engagement members fully engage the corresponding holes of the patient restraint board, then the thermoplastic mask system may by tightly secured to the patient restraint board by activating the lock-down mechanism.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a divisional application of pending application Ser. No. 10 / 924,547 filed Aug. 24, 2004, which claimed the benefit, under 35 U.S.C. § 119(e), of the provisional application filed Aug. 25, 2003 under 35 U.S.C. § 111(b), which was granted Ser. No. 60 / 497,618. Both applications are hereby incorporated by reference in their entireties.BACKGROUND OF THE INVENTION [0002] Cancer treatment using external beam radiation therapy is a common and growing method of treatment for patients with many kinds of cancers. In almost all of these patients, cancerous tissue lies adjacent to healthy tissue, which often contains important organs, nerves, and other structures that can be exquisitely sensitive to radiation injury. Therefore, during the course of treatment great care must be taken to spare normal tissue and only irradiate the cancerous tissue. [0003] The treatment process using external beam radiation therapy is complex and exac...
