20100119032 | PORTAL AND REAL TIME IMAGING FOR TREATMENT VERIFICATION - A system for radiotherapy includes a first imaging system and a second imaging system. The first imaging system generates projection images of an area of interest of an object, and the second imaging system generates portal images of the area of interest of the object synchronously with the generation of the projection images. The radiotherapy system further includes a processing system that receives data associated with the projection images and data associated with the portal images and reconstructs 3D and 4D portal images from the projection images and the portal images. | 05-13-2010 |
20100294279 | Hyperthermia Assisted Radiation Therapy - A breathing system for hyperthermic assisted radiation therapy includes at least one heating element that modulates the temperature of air inhaled by a patient, at least one cooling element that modulates the humidity of the air inhaled by a patient, and a controller that maintains the desired humidity and temperature. | 11-25-2010 |
20110185503 | Local Adjustment Device for Radiotherapy - A cradle for supporting an anatomical portion of a patient during radiotherapy includes a plurality of air chambers and at least one pressure regulator that adjusts the pressure in each air chamber. The cradle may be connected to an electronic control unit that sends instructions to the at least one pressure regulator to pressure each air chamber to a desired pressure. | 08-04-2011 |
20120020449 | Intensity modulated arc therapy with continuous couch rotation/shift and simultaneous cone beam imaging - A system for radiotherapy that includes a couch upon which a patient being treated by the system is positioned, the couch having continuous arc rotation for delivery accelerated irradiation to the patient. | 01-26-2012 |

20120163531 | TETRAHEDRON BEAM COMPUTED TOMOGRAPHY WITH MULTIPLE DETECTORS AND/OR SOURCE ARRAYS - A tetrahedron beam computed tomography system including an x ray source array that sequentially emits a plurality of x ray beams at different positions along a scanning direction and a collimator that intercepts the plurality of x-ray beams so that a plurality of fan-shaped x-ray beams emanate from the collimator towards an object. The system includes a first detector receiving a first set of fan-shaped x ray beams after they pass through the object, the first detector generating a first imaging signal for each of the received first set of fan-shaped x-ray beams and a second detector receiving a second set of fan-shaped x ray beams after they pass through the object, the second detector generating a second imaging signal for each of the received second set of fan-shaped x-ray beams. Each detector and source pair form a tetrahedral volume. In other embodiments, the system may also have more than two detectors arrays and/or more than one source array. Each pair of source array and detector array forms a tetrahedral volume. Using multiple detector arrays and source arrays can increase field of view, reduce the length of detector and source arrays so that the imaging system is more compact and mobile. | 06-28-2012 |
20120305007 | Local Adjustment Device For Radiotherapy - A cradle for positioning an anatomical portion of a patient during treatment includes a plurality of expandable fluid chambers and a pressure regulator configured to supply fluid to and withdraw fluid from each of the fluid chambers. A system for positioning an anatomical portion of a patient during treatment includes the aforementioned cradle and a control unit configured to control the pressure of each of the fluid chambers. A method for positioning an anatomical portion of a patient during treatment comprises the steps of placing the anatomical portion in the aforementioned cradle and adjusting the pressure of each of the fluid chambers to hold the anatomical portion in a desired position. | 12-06-2012 |
20140100408 | Intensity Modulated Arc Therapy with Continuous Coach Rotation/Shift and Simultaneous Cone Beam Imaging - A system for radiotherapy includes a couch having a top lateral surface upon which a patient being treated by the system is positioned. The couch has continuous arc rotation for delivery of accelerated irradiation to the patient. The couch is movable rotationally and translationally. Delivery of the accelerated irradiation is performed during at least a portion of the movement. | 04-10-2014 |
20140241505 | Compton Coincident Volumetric Imaging - A volumetric imaging device for constructing a three dimensional image includes a source, and absorbing detector, and an image constructor. The source includes a photon source, and a scatter detector arranged between the object and the photon source. The photon source emits photons towards the scatter detector. The scatter detector scatters at least some of the photons and detects the scattered photons. The object scatters at least some of the photons that were first scattered by the scatter detector. The absorbing detector is arranged to detect scattered photons from the object. The image constructor constructs the three dimensional image based on the scattered photons. | 08-28-2014 |
