| 20080206131 | Compositions and Method for Multimodal Imaging - Provided are signal modifying compositions for medical imaging comprising a carrier and two or more signal modifying agents specific for two or more imaging modalities. The compositions are characterized by retention efficiency, with respect to the signal modifying agents, which enables prolonged contrast imaging without significant depletion of the signal modifying agents from the carrier. The carriers of the present invention are lipid based or polymer based, the physico-chemical properties of which can be modified to entrap or chelate different signal modifying agents and mixtures thereof and to target specific organs or tumors or tissues within a mammal. | 08-28-2008 |

| 20090074150 | Cone-beam computed tomography with a flat-panel imager - A radiation therapy system that includes a radiation source that moves about a path and directs a beam of radiation towards an object and a cone-beam computer tomography system. The cone-beam computer tomography system includes an x-ray source that emits an x-ray beam in a cone-beam form towards an object to be imaged and an amorphous silicon flat-panel imager receiving x-rays after they pass through the object, the imager providing an image of the object. A computer is connected to the radiation source and the cone beam computerized tomography system, wherein the computer receives the image of the object and based on the image sends a signal to the radiation source that controls the path of the radiation source. | 03-19-2009 |

| 20100012829 | APPARATUS AND METHODS FOR REAL-TIME VERIFICATION OF RADIATION THERAPY - Various embodiments are described herein for an area integrated fluence monitoring sensor that can be used to measure a radiation dose. The sensor comprises at least one Gradient Ion Chamber (GIC) comprising an ion chamber having a volume gradient across a length or width thereof, a gas or liquid located within the ion chamber and an electrode to detect ions generated within the gas or liquid when the at least one GIC is subjected to an ionizing radiation beam. Various embodiments are also described herein for an Integral Quality Monitoring system and associated method that can be used to measure and monitor the quality of radiation doses provided by a radiation treatment system. | 01-21-2010 |
| 20100027744 | Image-guided multi-source radiotherapy - A highly compact, high-performance volumetric imaging system is proposed, that is integrated with a multi-source Cobalt-60 gamma irradiator for high throughput, high accuracy and minimally invasive fractioned treatments of intracranial, orbital and head-and-neck targets. | 02-04-2010 |
| 20110260729 | MAGNETIC RESONANCE IMAGING APPARATUS FOR USE WITH RADIOTHERAPY - A magnetic resonance imaging (MRI) apparatus suitable for radiotherapy. The apparatus includes two sets of coil pairs, each coil pair forming a Maxwell-like coil. The two sets of coil pairs share a common transverse plane, have opposing polarities, and define a common plane of symmetry and an imaging area. The two sets generate a substantially homogenous electromagnetic field in a first transverse direction in the imaging area and peripheral electromagnetic fields in a direction opposite to the first transverse direction in a peripheral area. The apparatus also includes at least one focusing magnet positioned in the peripheral areas to generate a focusing electromagnetic field in a focusing area, in a direction substantially the same as the first transverse direction. At least a portion of the peripheral electromagnetic fields is maintained in a defocusing area between the focusing area and the imaging area. | 10-27-2011 |

| 20110317812 | METHOD OF LOW ENERGY IMAGING IN THE PRESENCE OF HIGH ENERGY RADIATION - An apparatus and method obtain an image of an object from a first radiation source in the presence of a second radiation source. The first radiation source is directed at a first side of the object while the second radiation source is directed at the second side of the object. At least one portion of the radiation is detected at the second side of the object. A first signal is produced based on the at least one portion of detected radiation. The first signal has a first radiation component and a second radiation component. At least one other portion of radiation at the second side of the object is filtered and then detected. A second signal is produced based on the detected filtered radiation. The second signal has at least one of a filtered first radiation component and a filtered second radiation component. Then a third signal is produced from the first and second signals. The third signal is a representation of a first radiation component. | 12-29-2011 |
