Abstract: An optical scanner for three-dimensional scanning comprises: a support bed; a flat, transparent plate; guide rails under the transparent plate; a carriage slidably attached to the guide rails; and one or more sensors attached to the bed/case or carriage. For three-dimensional imaging, multiple scanned images of the object are obtained, each of which is from light reflecting off the object at a different angle with respect to the path of the carriage. This is done by shining light on the object and appropriately channeling reflected light, from at least two different directions, into the sensor(s). In one embodiment, the carriage has three CCD sensors, one oriented rearwards (with respect to the path of travel of the carriage), one oriented vertically, and one oriented forwards—each effectively “sees” the object from a different orientation. The multiple scanned images can be used for stereoscopic viewing and/or three-dimensional rendering using a computer.

Abstract: A novel method of gating electron emission from field-emitter cathodes for radio frequency (RF) electrode guns and a novel cathode that provides a focused electron beam without the need for magnetic fields or a curved cathode surface are provided. The phase and strength of a predefined harmonic field, such as the 3rd harmonic field, are adjusted relative to a fundamental field to cause a field emission cathode to emit electrons at predefined times for the generation of high-brightness electron beams. The emission time is gated responsive to the combined harmonic and fundamental fields and the response of the FE cathode to the combined fields. A planar focusing cathode includes a selected dielectric material, such as a ceramic material, to provide an electron beam emission surface. Metal surfaces are provided both radially around and behind the dielectric material to shape the electric fields that accelerate and guide the beam from the cathode surface.

Abstract: An ion or electron beam is steered or focussed by a circular magnetic field produced by passing a large electrical current through a straight conducting wire, the magnetic field being co-axial with the wire. Annular beams of charged particles coaxial with the straight wire can be focussed onto a circular spot or, depending upon the entry radius of the annular beam and the magnetic field strength, can be induced to follow a looping trajectory. The effect of the steering or focussing system can be enhanced by the provision of a cylindrical conductor which is co-axial with the straight conducting wire and maintained at a voltage sufficient to produce the desired particle trajectory such that the particle beam passes between the wire and the cylindrical conductor. The beam steering or focussing systems is applicable to the fields of beam current density intensification, ion implantation, ion separation and free electron lasers.

Abstract: Embodiments include methods and systems to perform computed tomography. Respiratory signal data and imaging data associated with a heart can be received, and a target area of the heart can be determined responsive to the imaging data. An initial energy and a direction of a proton beam to deliver a Bragg peak of the proton beam to the target area can be determined. The initial energy and the direction of the proton beam then can be modified responsive to the respiratory signal data to generate a modified initial energy and a modified direction. A proton computed tomography controller can be instructed to deliver the proton beam to the heart at the modified initial energy and the modified direction.

Abstract: Electron beam profile measurement method and system wherein a scanning system has a five-dimensional processing mechanism for measuring different cross sections of an e-beam profile in a path of the e-beam. Measurements are conducted using the scanning system by virtually dividing each cross section into a plurality of subsections and measuring independent current values of at least one wire (2) of the scanning system through which the electron beam passes from every pixel in each of the plurality of subsections. By providing relative movement between the scanning system and e-beam, e.g., moving the scanning system, the measured independent current values can be analyzed to obtain a distribution of current density of the cross-section of the e-beam.

Abstract: Systems and methods are provided to perform efficient, automatic adjustment of cyclotron beam currents within a wide range for multiple treatment layers within the same patient and treatment session; and to perform efficient, automatic cyclotron initialization, and calibration. In an embodiment, efficient adjustment is achieved by using beam current attenuation by an electrostatic vertical deflector installed in the inner center of the cyclotron. The beam current may, for example, be adjusted by the high voltage applied to the electrostatic vertical deflector, in front of each treatment the attenuation curve of the vertical deflector is recorded. Based on this attenuation curve, the vertical deflector voltage for the needed beam current of each irradiation layer is interpolated. In another embodiment, a process is provided that allows the automation of the initialization of a cyclotron after overnight or maintenance imposed shutdown. In one embodiment, five independent cyclotron system states are defined and the transition between one state to another may be automated, e.g., by the control system of the cyclotron.
