20080273659 | Radiation systems - A radiation system includes a first ring, a radiation source capable of providing radiation suitable for treating a patient, the radiation source secured to the first ring, a second ring located behind the first ring, and an imager secured to the second ring. A radiation system includes a first device having a radiation source capable of generating a radiation beam suitable for treating a patient, and a second device having imaging capability, wherein the first device is oriented at an angle that is less than 180° relative to the second device. A radiation system includes a structure having a first opening, a radiation source rotatably coupled to the structure, an imaging device rotatable relative to the structure, and a processor for controlling a rotation of the radiation source and a rotation of the imaging device, wherein the radiation source is rotatable relative to the imaging device. | 11-06-2008 |
20110075815 | BEAM FILTER POSITIONING DEVICE - A system includes a beam filter positioning device including a plate configured to support one or more beam filters, and one or more axes operable to move the plate relative to a beam line. A control mechanism is coupled to the one or more axes for controlling the movement of the axes and configured to automatically adjust the position of at least one of the one or more beam filters relative to the beam line. | 03-31-2011 |

20120043481 | MULTILEAF COLLIMATORS WITH TRANSVERSE MOTION - A collimation assembly includes a multileaf collimator and motion assembly. The multileaf collimator includes a support body and a plurality of pairs of beam blocking leaves supported by the support body. The beam blocking leaves are longitudinally movable in a first direction. The motion assembly includes an actuator and a guide assembly operable to move the support body and thereby allowing the plurality of pairs of beam blocking leaves to move in a second direction generally transverse to the first direction. | 02-23-2012 |
20120043482 | MULTI LEVEL MULTILEAF COLLIMATORS - A multilevel MLC includes a first set and a second set of a plurality of pairs of beam blocking leaves arranged adjacent one another. Leaves of each pair in the first set are disposed in an opposed relationship and longitudinally movable relative to each other in a first direction. Leaves of each pair in the second set are disposed in an opposed relationship and longitudinally movable relative to each other in a second direction generally parallel to the first direction. The first and second sets of pairs of leaves are disposed in different planes. | 02-23-2012 |
20120087478 | BEAM FILTER POSITIONING DEVICE - A system includes a beam filter positioning device including a plate configured to support one or more beam filters, and one or more axes operable to move the plate relative to a beam line. A control mechanism is coupled to the one or more axes for controlling the movement of the axes and configured to automatically adjust the position of at least one of the one or more beam filters relative to the beam line. | 04-12-2012 |
20130144104 | RADIATION SYSTEMS WITH MINIMAL OR NO SHIELDING REQUIREMENT ON BUILDING - A radiation system includes a support, a capsule rotatably coupled to the support, a radiation source movably coupled to the capsule, wherein the radiation source is configured to provide a treatment radiation beam, and is capable of being turned on or off in response to a control signal, and a collimator located next to the radiation source, wherein the capsule defines a space for accommodating a portion of a patient, and includes a shielding material for attenuating radiation resulted from an operation of the radiation source, and wherein the shielding material is configured to limit a radiation exposure level to 5 mR/hr or less within 3 meters from an isocenter. | 06-06-2013 |
20140112453 | MULTI LEVEL MULTILEAF COLLIMATORS - A multilevel MLC includes a first set and a second set of a plurality of pairs of beam blocking leaves arranged adjacent one another. Leaves of each pair in the first set are disposed in an opposed relationship and longitudinally movable relative to each other in a first direction. Leaves of each pair in the second set are disposed in an opposed relationship and longitudinally movable relative to each other in a second direction generally parallel to the first direction. The first and second sets of pairs of leaves are disposed in different planes. | 04-24-2014 |
20140171725 | RADIATION SYSTEMS WITH MINIMAL OR NO SHIELDING REQUIREMENT ON BUILDING - A radiation system includes: a first support; a first structure rotatably coupled to the first support so that the first structure is rotatable about a first axis relative to the first support; a second structure rotatably coupled to the first structure so that the second structure is rotatable about a second axis that forms a non-zero angle relative to the first structure; and a first radiation source connected to the second structure; wherein the first structure and the second structure are parts of a capsule for accommodating at least a portion of a patient. | 06-19-2014 |
