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.

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: 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.

Abstract: A computer software system comprising a view sub-system including presentation objects which provide a user interface, a business logic sub-system including business object implementation objects which hold business data and implement business logic, a handler sub-system including controller objects which control the sequence of actions in a use case, and a view context sub-system including context objects which capture input/output data. The invention also provides a related computer program and a related method of passing data in an object oriented application.

Abstract: A double-gate field effect transistor (DGFET) is provided using a damascene-like replacement gate processing step to create sidewall source/drain regions, oxide spacers and gate structures inside a previously formed trench. The damascene-like replacement gate processing step allows for the fabrication of a tapered transistor body region having a thicker body under the contacts which reduces access resistance.
