US Patent:

7046765, May 16, 2006

Filed:

Mar 31, 2004

Appl. No.:

10/814451

Inventors:

Phillip Wong - San Francisco CA, US
James Wang - Fremont CA, US
Sohail Saych - San Jose CA, US

Assignee:

Accuray, Inc. - Sunnyvale CA

International Classification:

H05G 1/54

US Classification:

378117

Abstract:

The present invention provides a radiosurgery and/or radiotherapy x-ray system including a collision avoidance subsystem for detecting and avoiding obstacles during treatment. The system includes an x-ray source having an emission head at a distal end of an articulated arm assembly extending from a base unit, with the head being adapted for selectively emitting an x-ray beam along a beam axis, and including an associated controller for selectively orienting the head whereby the beam extends along a succession of treatment axes. The system further includes a collision avoidance subsystem including means for preventing the head and arm assembly from effecting a collision with an object in one or more pre-computed exclusion zones.

International Classification:

H05G 1/54

US Classification:

378117

Abstract:

A method for preventing an emission head or arm assembly from entering an exclusion zone. The method may include calculating a variable dimension exclusion zone of a radiosurgery system, and preventing at least one of the emission head or arm assembly from entering the variable dimension exclusion zone. The method may also include establishing a exclusion zone of a radiosurgery system, the radiosurgery system comprising an x-ray source having an emission head, moving the emission head during treatment of a patient, wherein the exclusion zone travels with the emission head, and detecting a presence and location of an object in the traveling exclusion zone.

International Classification:

H05G 1/54

US Classification:

378117

Abstract:

A method for preventing an emission head or arm assembly from entering an exclusion zone or for preventing a collision between an object and the emission head and/or arm assembly. The method may include modeling a treatment room using a computer-aided design (CAD) tool, and calculating an exclusion zone for a radiosurgery system in the treatment room using the modeled treatment room.

Abstract:

Autonomous data machines and systems may be provided, which may be deployed in an environment. The machines may roam within the environment and collect data with aid of one or more sensors. The data may be sent to a control center, which may optionally receive information from additional data sources, such as other on-site sensors, existing static data, or real-time social data. The control center may send instructions to the machines to perform one or more reaction based on the received information. The autonomous data machines may be capable of reacting autonomously to one or more detected condition. In some instances, the autonomous data machines may be employed for security or surveillance.
