20110052117 | INTEGRATED CIRCUIT WITH PINS AT MULTIPLE EDGES OF A CHIP - An improved integrated circuit (IC) layout is described that provides conductive pads on opposite sides of a substrate. The conductive pads provide for connectivity to the chip in different chip orientations. Accordingly, multiple chips having the same layout can be provided in a package, instead of providing each chip with a different layout. Since the same layout may be used for each chip, manufacturing costs are reduced. | 03-03-2011 |
20110204507 | TWO-SHELF INTERCONNECT - Consistent with the present disclosure, a package is provided that includes a housing having a recessed portion to accommodate an integrated circuit or chip. The housing has an inner periphery that defines or delineates the recessed portion. The inner periphery may be stepped and includes first and second surfaces that are spaced vertically from one another and extend in respective parallel planes, for example, to thereby constitute first and second shelves. First bonding pads or contacts (“housing pads”) may be provided on the first surface, which may electrically connect or interconnect with first pads on the integrated circuit (“IC pads”), and second housing pads may be provided on the second surface, which can electrically connect or interconnect with second IC pads. Thus, the IC pads connect to corresponding housing pads on the inner periphery of the housing that are above and below one another. Since the housing pads are not provided on the same surface, the number of housing pads on each step or shelf of the periphery can be reduced, and the housing pads can be spaced from one another by a spacing or pitch that is greater than that of the IC pads. Accordingly, the dimensions and spacing of the housing pads may comply with relevant design rules, while providing connection to an increased number of IC pads. | 08-25-2011 |

20100310144 | Method for Dynamic Prior Image Constrained Image Reconstruction - A method for reconstructing a high quality image from undersampled image data is provided. The image reconstruction method is applicable to a number of different imaging modalities. Specifically, the present invention provides an image reconstruction method that incorporates an appropriate prior image into the image reconstruction process. One aspect of the invention is to provide an image reconstruction method that produces a time series of desired images indicative of a higher temporal resolution than is ordinarily achievable with the imaging system, while mitigating undesired image artifacts. This is generally achieved by incorporating a limited amount of additional image data into the data consistency condition imposed during a prior image constrained image reconstruction. For example, cardiac phase images can be produced with high temporal resolution using a state-of-the-art multi-detector CT system with either fast gantry rotation speed or CT imaging system with a slow gantry rotation speed. | 12-09-2010 |
20110286646 | Method For Radiation Dose Reduction Using Prior Image Constrained Image Reconstruction - A method for reconstructing an image of a subject with a medical imaging system is provided. Image data is acquired with the medical imaging system, typically in an undersampled manner. A prior image constrained compressed sensing (PICCS) image reconstruction method is then implemented to reconstruct images of the subject being imaged. The prior image used in such a method is produced from so-called averaged image data. The averaged image data is produced by effectively averaging signal information associated with a plurality of different slice locations along a direction orthogonal to the plane parallel to the slice locations. Weightings are calculated from images reconstructed in a conventional manner from the acquired image data, and these weightings are employed to produce the averaged image data. By producing a prior image in this manner, a higher signal-to-noise ratio is achievable, allowing trade-offs with factors such as radiation dose in x-ray imaging. | 11-24-2011 |
20120177267 | Method For Constrained Reconstruction of High Signal-To-Noise Ratio Images - A method for producing an image having a high signal-to-noise ratio (SNR) is provided. An image to be enhanced is provided, the provided image including a previously reconstructed image or an image reconstructed from acquired image data. A prior image is produced from the provided image, for example, by filtering the provided image such that noise from the provided image is substantially suppressed in the prior image. Synthesized image data is produced by performing a forward projection of the provided image. A sparsified image is produced by subtracting the prior image and the provided image. A target image having a higher SNR than the provided image is reconstructed using the sparsified image, the provided image, and the synthesized image data. The provided image may be, for example, a medical image produced by an x-ray imaging system, including computed tomography and C-arm systems; a magnetic resonance imaging system; and the like. | 07-12-2012 |
20140270454 | SYSTEM AND METHOD FOR ESTIMATING A STATISTICAL NOISE MAP IN X-RAY IMAGING APPLICATIONS - Described here are a system and method for producing a statistical noise map that indicates the noise present in data acquired with an x-ray imaging system, such as an x-ray computed tomography system, an x-ray tomosynthesis system, a C-arm x-ray imaging system, and so on. In general, an image is reconstructed from the acquired data using, for example, any standard filtered back projection (“FBP”) image reconstruction algorithm. This image is used as a base line to estimate a noise standard distribution map. The raw projection data represents a typical measurement among many repeated measurements under the same experimental conditions; therefore, the measured projection data can be used to numerically generate an ensemble of many (e.g., twenty or more) noisy projection data sets. These noisy projection data sets are then used to reconstruct noisy images and from these noisy images and the original image, the statistical noise map can be computed. | 09-18-2014 |

The image reconstruction is decomposed into separate linear sub-problems that can be more efficiently solved. A statistical image reconstruction process is decomposed into a statistically-weighted algebraic reconstruction update sequence. After this step, the reconstructed image is denoised using a regularization function. | 03-26-2015 |
