| 20100272238 | Sysstem for reduction of exposure to X-ray Radiation To reduce X-ray exposure, an area of interest is selected in the image. The image of the selected area is updated frequently, comparable to rate of updates used today for the whole image. The rest of the image is updated at a significantly lower rate. Since the area of ... | 10/28/2010 |
| 20090080619 | MULTILEAF COLLIMATOR A multileaf collimator includes a first leaf block group including plural leaf blocks, a second leaf block group including plural leaf blocks arranged in the same direction as the first leaf block group and disposed opposite the leaf blocks of the first leaf block group... | 03/26/2009 |
| 20090060144 | AUTOMATED X-RAY OPTIC ALIGNMENT WITH FOUR-SECTOR SENSOR A system for x-ray optical alignment. The system includes an x-ray source, an optic, a collimation element, and alignment sensors. The x-ray source generates an x-ray beam that is directed by the optic at a sample. The collimation element is located between the optic an... | 03/05/2009 |
| 20080317212 | X-RAY RADIATION DIAPHRAGM AND CONTROL METHOD THEREFOR, AND CT DEVICE EMBODYING SAME A collimator device has at least one masking device that is adjustable between two end positions for collimation of a beam fan in an x-ray CT device, wherein the x-ray fan is schematically not masked in a first end position. The x-ray beam is more than half-masked in a ... | 12/25/2008 |
| 20070211851 | X-RAY DIAGNOSIS APPARATUS An X-ray diagnosis apparatus is configured to control at least one of the X-ray diaphragm which restricts the irradiation range of the X-ray and the compensation filter which attenuates the amount of the X-ray based on at least one of the rotation position or the positi... | 09/13/2007 |
| 20060067481 | Radiation collimation In a collimator assembly for an X-ray imaging system comprising adjustable X-ray attenuating collimator vanes that define the area of a patient to be exposed to an X-ray beam, the collimator vanes (1, 2, 3, 4) are automatically driven under the control of an imag... | 03/30/2006 |
| 20060039536 | Collimator control method and X-ray CT apparatus A collimator control method for an X-ray CT apparatus includes changing an aperture of the collimator according to a position of a helical scan on the body axis of the subject in the progress of the helical scan. ... | 02/23/2006 |
| 20050123098 | Method and apparatus for optimization of collimator angles in intensity modulated radiation therapy treatment A method and apparatus to determine an optimum collimator angle of a multi-leaf collimator having an opening and multiple leaf pairs for closing portions of the opening to form a radiation beam arrangement having multiple radiation beam segments. The method and apparatu... | 06/09/2005 |
| 20050013410 | X-ray examination method and apparatus with automatic gating of the x-ray beam An x-ray apparatus has an exposure unit with an x-ray radiator and a diaphragm in front thereof, and a camera system with which an adjustment image is acquired of a subject positioned in front of an x-ray exposure plane. Using the adjustment image, a region to be examin... | 01/20/2005 |
