| 20130083886 | METHOD AND SYSTEM FOR PERFORMING LOW-DOSE CT IMAGING - A method includes generating higher resolution image data based on undersampled higher resolution projection data and incomplete lower resolution projection data. The undersampled higher resolution projection data and the incomplete lower resolution projection data are acquired during different acquisition intervals of the same scan. A system includes a radiation source configured to alternately modulate emission radiation flux between higher and lower fluxes during different integration periods of a scan, a detector array configured to alternately switch detector pixel multiplexing between higher and lower resolutions in coordination with modulation of the fluxes, and a reconstructor configured to reconstruct higher resolution image data based on projection data corresponding to undersampled higher resolution projection data and incomplete lower resolution projection data. | 2013-04-04 |
| 20130083887 | DETECTOR MODULES AND METHODS OF MANUFACTURING - Detector modules and methods of manufacturing are provided. One detector module includes a detector having a silicon wafer structure formed from a first layer having a first resistivity and a second layer having a second resistivity, wherein the first resistivity is greater than the second resistivity. The detector further includes a photosensor device provided with the first layer on a first side of the silicon wafer and one or more readout electronics provided with the second layer on a second side of the silicon wafer, with the first side being a different side than the second side. | 2013-04-04 |
| 20130083888 | APPARATUS FOR DETECTING VOLUME OF FOREIGN SUBSTANCE EXISTED IN CORE OF GEOLOGICAL SAMPLE USING COMPUTER TOMOGRAPHY APPARATUS AND METHOD THEREOF - An apparatus for detecting a volume of a foreign substance existed in a core of a geological sample using a computer tomography apparatus and a method thereof, more particularly an apparatus for detecting a volume of a foreign substance existed in a core of a geological sample using a computer tomography apparatus and a method thereof capable of calculating a volume of any one object among the foreign substance existed in the core. | 2013-04-04 |
| 20130083889 | TIME-RESOLVED TOMOSYNTHESIS IMAGING - A method for time-resolved tomosynthesis imaging for a moving object includes moving an imaging device having an x-ray source and an x-ray detector around the moving object and recording raw image data for a temporal series of tomosynthesis images. The method also includes reconstructing the temporal series of tomosynthesis images from the raw image data. While the imaging device is being moved, a motion speed of the imaging device is matched to a speed, at which the moving object is moving. | 2013-04-04 |
