| 20080210877 | Double Decker Detector For Spectral Ct - A radiation detector ( | 09-04-2008 |
| 20090252285 | CT SCANNER USING INJECTED CONTRAST AGENT AND METHOD OF USE - A CT scanner includes a first X-ray beam source, and a second X-ray beam source. With such an apparatus, first source is used to monitor buildup of an injected contrast agent in a selected region of interest relative to a patient and at least the second source is used to perform diagnostic scanning when the buildup of the contrast agent reaches a desired level. | 10-08-2009 |
| 20090304142 | CT SCANNER WITH SCATTER RADIATION CORRECTION AND METHOD OF USING SAME - A CT scanner with scatter correction device and a method for scatter correction are provided. The method of correcting CT images from artifacts caused by scattered radiation comprises affixing to the non-rotating frame of the CT gantry a plurality of shields for shielding some of the CT detector elements from direct X ray radiation, while allowing scattered radiation to arrive at said shielded elements; measuring scatter signals from said shielded elements, indicative of scattered radiation intensity; and correcting for scatter by subtracting scatter intensity values estimated from said measured scatter signals from signals measured by unshielded detector elements. | 12-10-2009 |
| 20100195804 | METHOD FOR CALIBRATION OF A CT SCANNER - A method for calibration of a CT scanner having an x-ray source and a detector having an axial extent in the scanner, the source being rotatable about an epicenter between the source and detector, the method comprising:
