Patent number: 6907106Abstract: An apparatus and method for irradiating target objects, especially medical stents for in vivo implantation. A linear accelerator provides a high energy electron beam that impinges upon and is received by an x-ray conversion target. The x-ray conversion target is activated by either a static or dynamically moveable electron beam to generate and emit an x-ray flux so as to efficiently intercept the target object. The x-ray flux is directed to the target object for a desired time period and is of sufficiently high energy to efficiently impart radioactive properties to the target object. Alternatively, the target object is positioned within the path of the x-ray flux or is translated within the path during irradiation. Mechanical transport assemblies such as a carousel, rotational and/or linear translator and/or movement tube system also may be provided.Type: GrantFiled: August 23, 1999Date of Patent: June 14, 2005Assignee: Varian Medical Systems, Inc.Inventors: Raymond D McIntyre, Stanley W Johnsen, Marcel Marc, Michelangelo Delfino, Edward Seppi

Patent number: 4877961Abstract: A beam of charged particles is scattered by a thin foil and the flux at two angles .theta..sub.1 and .theta..sub.2, is sampled to yield an exponential function of the respective energy difference, E(.theta..sub.2)-E(.theta..sub.1). For .theta..sub.1 =0.degree., a signal representative of the energy stability of the beam is obtained and compared with a reference to form an error signal for application to the accelerator for stabilizing the beam energy and/or providing an energy interlock.Type: GrantFiled: October 26, 1988Date of Patent: October 31, 1989Assignee: Varian Associates, Inc.Inventors: Raymond D. McIntyre, Stanley W. Johnsen

Patent number: 4687936Abstract: A system for scanning a beam of charged-particles across a target is described which compensates for energy dispersion in the beam. A time-varying magnet with circular pole pieces is used to sweep the beam left to right. Two wedge-shaped magnet dipoles, one on each side of the center line are used to bend the beam parallel to the center line and compensate for beam energy dispersion.Type: GrantFiled: December 17, 1985Date of Patent: August 18, 1987Assignee: Varian Associates, Inc.Inventors: Raymond D.

Patent number: 3969629Abstract: In an x-ray treatment machine a charged particle accelerator or cobalt source is provided for producing a field of high energy x-ray radiation for application to a body, for treatment thereof. The radiation machine includes collimators and field shaping structures for shaping the field of x-ray radiation applied to the body. The high energy x-ray radiation intercepted by the field shaping and collimating structures produces high energy secondary electrons by a number of different atomic processes. These energetic secondaries contaminate the shaped radiation field applied to the body being treated. The contaminating high energy electrons, if not eliminated, substantially increase the dosage of radiation delivered to the surface of the body.Type: GrantFiled: March 14, 1975Date of Patent: July 13, 1976Assignee: Varian AssociatesInventor: Raymond D.

Patent number: 3955089Abstract: In a high energy X-ray therapy machine, an accelerator accelerates a beam of electrons to energies of several MEV. The electron beam is directed, generally via a beam deflector, onto an X-ray target to produce X-rays for treating a patient. The accelerator and beam deflector are often carried within a rotatable gantry structure, movable for radiating the patient through a series of angular positions or ports. A plurality of ionization chamber radiation detectors are disposed in the radiation field surrounding the beam path of the accelerated electron beam. Ionization current signals are compared from a plurality of the detectors to derive an error signal determinative of a deviation of the beam from an intended beam path. The error signal is utilized to energize beam steering coils for steering the beam along the predetermined beam path.Type: GrantFiled: October 21, 1974Date of Patent: May 4, 1976Assignee: Varian AssociatesInventors: Raymond D. McIntyre, Jay D. Wood
