20120002780 | METHOD AND APPARATUS FOR BREATHING ADAPTED IMAGING - A method is provided for imaging a portion of a patient that moves as a patient breathes. A motion map is produced of the portion's motion during a breathing cycle of the patient. A scanning protocol is generated using information obtained from the motion map for a given source/detector position and a given point in the breathing cycle. The scanning protocol comprises at least one setting for at least one imaging apparatus component such that a desired amount of x-ray dosage is applied to the portion of the patient at the given source/detector position and the given point in the breathing cycle. An imaging scan is performed of the portion of the patient. The at least one imaging apparatus component is adjusted during the imaging scan. | 01-05-2012 |
20130044856 | INTERVENTIONAL IMAGING AND DATA PROCESSING - An imaging system includes a radiation source that emits radiation that traverses an examination region. A controller activates the radiation source to emit radiation and deactivates the radiation source to stop radiation emission. The controller selectively activates the radiation source to emit radiation at one or more pre-determined angles. In another embodiment, the imaging system includes a data processing component that generates a virtual three dimensional image of an object of interest of the scanned subject based on the image data. In another embodiment, the imaging system is in a communication with a data manipulation and packaging component that generates at least a two dimensional or a three dimensional data set based on the volumetric image data and packages the data set in an object provided to a remote system that manipulates and navigates through the data set. | 02-21-2013 |
20130243297 | FORWARD PROJECTION APPARATUS - The invention relates to a forward projection apparatus for performing a forward projection through an image ( | 09-19-2013 |
20130251286 | ITERATIVE RECONSTRUCTION ALGORITHM WITH A CONSTANT VARIANCE BASED WEIGHTING FACTOR - A method includes reconstructing measured projection data using an iterative statistical reconstruction algorithm that reduces image artifact caused by differences in variances in projections of the measured projection data used to update a voxel of the image for one or more voxels of the image. A reconstructor includes a processor that reconstructs measured projection data using an iterative statistical reconstruction algorithm that reduces or mitigates image artifact caused by differences in variances in projections used to update a voxel of the image for one or more voxels of the image. A computer readable storage medium encoded with computer executable instructions, which, when executed by a processor of a computer, cause the processor to: reduce image artifact caused by differences in variances in projections used to update a voxel of an image for one or more voxels of the image using an iterative statistical reconstruction algorithm. | 09-26-2013 |

20140037046 | DYNAMIC PERFUSION IMAGING - A method includes scanning a region of interest, during a contrast agent based perfusion scan, at a predetermined temporal sampling rate during contrast agent uptake in the region of interest, and generating time frame data indicative of the scanned region of interest. The method further includes identifying a predetermined change in an amount of the contrast agent in the region of interest from the time frame data. The method further includes scanning the region of interest at a lower temporal sampling rate, which is lower than the temporal sampling rate during the contrast agent uptake, in response to identifying the predetermined change in the amount of the contrast agent in the region of interest. | 02-06-2014 |
