Publication number: 20120104276Abstract: A radiation treatment system (100) for accurately delivering radiation to a targeted site within a cancer patient (108) that includes a modular patient support system and a patient positioner (114). The modular patient support system includes a modularly expandable patient pod (200) and at least one immobilization device, such as, for example, a rigid moldable foam cradle (350). The patient pod (200) includes a generally hemi-cylindrical support shell (212) that extends longitudinally between proximal edge (214) and distal edge (216), and transversely between two lateral edges (222, 224). In one embodiment, the lateral edges (222, 224) are tapered to minimize edge effects that result when radiation beams traverse the lateral edges (222, 224).Type: ApplicationFiled: January 6, 2012Publication date: May 3, 2012Applicant: Loma Linda University Medical CenterInventors: Daniel W. Miller, Steve K. McAllaster, Jerry D. Slater, Nickolas S. Rigney, Daniel C. Anderson, Michael F. Moyers

Publication number: 20110218679Abstract: Apparatus and methods for therapy delivery are disclosed. In one embodiment, a therapy delivery system includes a plurality of movable components including a radiation therapy nozzle and a patient pod for holding a patient, a patient registration module for determining a desired position of at least one of the plurality of movable components, and a motion control module for coordinating the movement of the least one of the plurality of movable components from a current position to the desired position.

Patent number: 7984715Abstract: Support devices and pods for the head and neck region of patients undergoing radiation therapy are provided herein. The pod generally includes a support shell shaped to generally conform to the shape of the head and neck region of the patient, a foam insert that conforms to the head and neck region of the patient, and an immobilization facemask attached directly to the shell, thereby facilitating close placement of the radiation beam delivery device to the patient and reducing any attenuation and perturbation of radiation doses directed at the patient. The components of the pod are made from materials having properties that reduce any attenuation and perturbation of prescribed radiation doses.Type: GrantFiled: May 8, 2006Date of Patent: July 26, 2011Assignee: Loma Linda University Medical CenterInventor: Michael F. Moyers

Path planning and collision avoidance for movement of instruments in a radiation therapy environment
Patent number: 7949096Abstract: A patient positioning system for use with a radiation therapy system that monitors the location of fixed and movable components and pre-plans movement of the movable components so as to inhibit movement if a collision would be indicated. The positioning system can also coordinate movement of multiple movable components for reduced overall latency in registering a patient. The positioning system includes external measurement devices which measure the location and orientation of objects, including components of the radiation therapy system, in space and can also monitor for intrusion into the active area of the therapy system by personnel or foreign objects to improve operational safety of the radiation therapy system.Type: GrantFiled: June 28, 2010Date of Patent: May 24, 2011Assignee: Loma Linda University Medical CenterInventors: Chieh C.
