20080217561 | PHANTOM FOR ION RANGE DETECTION - A phantom for heavy ion radiation therapy provides characterization of an ion beam that may enter but not exit from the phantom. The phantom may include multiple materials and multiple spatially dispersed ion detectors to obtain signals that may be fit to known beam curves to accurately characterize the location and other parameters of Bragg peak of a given ion beam within a patient. | 09-11-2008 |
20080260098 | AREAL MODULATOR FOR INTENSITY MODULATED RADIATION THERAPY - A modulator for radiation therapy provides modulation of an area beam to decrease treatment time. Separate channels passing modulated “beamlets” are possible by spacing the channels such that spreading of the beams and multiple angles of treatment eliminate cold spots. The space between the channels allows well-defined channel walls and space for modulator mechanisms. | 10-23-2008 |
20090189095 | ION RADIATION THERAPY SYSTEM WITH VARIABLE BEAM RESOLUTION - An ion radiation therapy machine provides a steerable beam for treating a tumor within the patient where the exposure spot of the beam is controlled in width and/or length to effect a flexible trade-off between treatment speed, accuracy, and uniformity. | 07-30-2009 |
20090200481 | ION RADIATION THERAPY SYSTEM HAVING MAGNETIC FAN BEAM FORMER - An improved beam forming system for ions used in radiation treatment employs a magnet system of successive quadrupole magnets to convert an ion pencil beam to a fan beam with reduced neutrons production compared with conventional beam spreading techniques using scattering foils. | 08-13-2009 |
20090212231 | HEAVY ION RADIATION THERAPY SYSTEM WITH STAIR-STEP MODULATION - A system for modulating a fan beam for radiation treatment employs shutters that may move rapidly into and out of different beamlets of a fan beam, the shutters having a systematic weighting so that a limited number of shutters may obtain a far greater number of regularly spaced energy reductions. | 08-27-2009 |
20090289192 | SCANNING APERTURE ION BEAM MODULATOR - A modulator for ions such as protons employs multiple shutter pairs to create independently movable apertures effecting a multiple pencil beam treatment of the patient thereby increasing treatment speed by eliminating the need for a custom compensator. | 11-26-2009 |
20100006778 | ION RADIATION THERAPY SYSTEM WITH DISTAL GRADIENT TRACKING - An ion radiation therapy machine provides a control of the range of the ion beam that a Bragg peak of the beam is located according to a determined gradient of the dose plan. | 01-14-2010 |
20100019167 | FAN BEAM MODULATOR FOR ION BEAMS PROVIDING CONTINUOUS INTENSITY MODULATION - An intensity modulator for controlling the intensity of ions, such as protons, controllably block a portion of sub-areas of an area beam to control the average intensity within that sub-area. A fan beam is then created by a focusing process that reforms the area beam while blurring intensity variations in each sub-area to a corresponding beamlet in the fan beam of uniform intensity. | 01-28-2010 |
20100176309 | ION RADIATION THERAPY SYSTEM WITH ROCKING GANTRY MOTION - A radiation therapy system for heavy ions employs a rocking motion of a fan beam used to treat the patient, the fan beam having individually modulated beamlets, the rocking limited in angular extent to provide improved conformance of the dose to a tumor while shielding distal tissue from radiation. | 07-15-2010 |
20100189220 | SYSTEM AND METHOD FOR OPTIMIZATION OF A RADIATION THERAPY PLAN IN THE PRESENCE OF MOTION - A computer-implemented method for optimizing a radiation treatment plan for a radiotherapy machine providing independently controlled radiation along a plurality of rays j directed toward a patient and configured to account for the effects of patient motion. The method includes generating a probability distribution function quantitatively expressing patient motion, identifying a prescribed total dose D | 07-29-2010 |
20100243921 | ION RADIATION THERAPY SYSTEM WITH VARIABLE BEAM RESOLUTION - An ion radiation therapy machine provides a steerable beam for treating a tumor within the patient where the exposure spot of the beam is controlled in width and/or length to effect a flexible trade-off between treatment speed, accuracy, and uniformity. | 09-30-2010 |
20100252728 | Mass Spectrometer Using An Accelerating Traveling Wave - A mass spectrogram employs a set of controllable electrodes to produce a time varying axially inhomogenous electric field and enhance separation of charged particles by exposing the charged particles to different electric field strengths based on their spatial positions. The fields may be tailored to provide a traveling wave that expands portions of a spectrographic plot of the particles and/or to provide focusing or other effects. | 10-07-2010 |
20130189435 | Three-Dimensional Printing System Using Dual Rotation Axes - A 3-D printer system moves a printed tool over a print surface with a mechanism controlling a rotational angle of an arm holding the print tool and a revolutionary angle of axis of rotation of the printable area to eliminate the disadvantages of conventionally used linear motion mechanisms | 07-25-2013 |
20140125790 | Device And Method For Three Dimensional Imaging Of Biological Sample - A device and method are provided for generating a three dimensional image of a volume of biological material. A plurality of layers of biological material are sequentially removed therefrom. Images of each layer of the biological sample are captured prior to removal. Each image includes information from a layer and from a portion of the biological material below the layer. The information from the layer is isolated from the portion of material below the layer for each image. The three dimensional image is generated from the isolated information of each layer. | 05-08-2014 |
