Publication number: 20120308104Abstract: Photon starvation causes streaks and noise and seriously impairs the diagnostic value of the CT imaging. To reduce streaks and noise, a new scheme of adaptive Gaussian filtering relies on the diffusion-derived scale-space concept in one embodiment of the current invention. In scale-space view, filtering by Gaussians of different sizes is similar to decompose the data into a sequence of scales. As the scale measure, the variance of the filter linearly relates to the noise standard deviation of a predetermined noise model in the new filtering method. The new filter has only one optional parameter that remains stable once tuned. Although single-pass processing using the new filter generally achieves desired results, iterations are optionally performed.Type: ApplicationFiled: June 6, 2011Publication date: December 6, 2012Applicants: TOSHIBA MEDICAL SYSTEMS CORPORATION, KABUSHIKI KAISHA TOSHIBAInventors: Zhi YANG, Alexander ZAMYATIN, Yu ZOU, Michael D.

Patent number: 8294717Abstract: Three or more materials are advantageously separated from dual energy data by using a material separation technique. To effectively separate material clusters, a density plot is introduced to automatically render cluster separations. Initially, the projection data optionally undergo data-domain dual energy decomposition. Then, the image data is plotted in a vector plot whose axes are the low HU values and the high HU values. For a given data point in the vector plot, a number of data points is counted within in a region of interest surrounding the given data point to generate a density plot where each point now represents a density level surrounding the data point. Thus, clustering of a certain material is visualized by a predetermined color assignment scheme. Furthermore, special image processing methods such as Gaussian decomposition are used to improve the accuracy of material separation.Type: GrantFiled: June 26, 2009Date of Patent: October 23, 2012Assignees: Kabushiki Kaisha Toshiba, Toshiba Medical Systems CorporationInventors: Alexander Zamyatin, Anusha Muthu Natarajan, Yu Zou

Patent number: 8283584Abstract: An electronic device includes a housing and a button. The housing defines a through hole. The sidewall of the through hole defines a pair of positioning holes. The button includes a frame, a sliding bar assembly, an elastic conductive member, and a pressing member. The sliding bar assembly is received in the frame with two external ends respectively received in the positioning holes to cause the frame to be received in the through hole. The elastic conductive member is fixed in the housing. The pressing member hooks the frame and extends through the frame to resist the sliding bar assembly.

Publication number: 20120183223Abstract: Described is a technology by which online recognition of handwritten input data is combined with offline recognition and processing to obtain a combined recognition result. In general, the combination improves overall recognition accuracy. In one aspect, online and offline recognition is separately performed to obtain online and offline character-level recognition scores for candidates (hypotheses). A statistical analysis-based combination algorithm, an AdaBoost algorithm, and/or a neural network-based combination may determine a combination function to combine the scores to produce a result set of one or more results. Online and offline radical-level recognition may be performed. For example, a HMM recognizer may generate online radical scores used to build a radical graph, which is then rescored using the offline radical recognition scores. Paths in the rescored graph are then searched to provide the combined recognition result, e.g., corresponding to the path with the highest score.Type: ApplicationFiled: March 21, 2012Publication date: July 19, 2012Applicant: Microsoft CorporationInventors: Xinjian Chen, Dongmei Zhang, Yu Zou, Ming Chang, Shi Han, Jian Wang

Patent number: 8194961Abstract: A method of obtaining a computed tomography image of an object includes determining linear terms and non-linear beam hardening terms in a pair of line integral equations for dual-energy projection data from inserting average and difference from average attenuation terms, obtaining an initial solution of the line integral equation by setting the non-linear beam hardening terms to zero, and iteratively solving the line integral equations to obtain one line integral equations for each basis material. Attenuation by the first basis material corresponds to a photoelectric attenuation process, and attenuation by the second basis material corresponds to a Compton attenuation process. The line integral equations can be inverted by an inverse Radon procedure such as filtered backprojection to give images of each basis material. The images of each basis material can then be optionally combined to give monochromatic images, density and effective atomic number images, or photoelectric and Compton processes images.Type: GrantFiled: April 21, 2008Date of Patent: June 5, 2012Assignees: Kabushiki Kaisha Toshiba, Toshiba Medical Systems CorporationInventors: Yu Zou, Michael D.

Patent number: 8165264Abstract: Fast kV-switching is a dual energy acquisition technique in computed tomography (CT) in which alternating views correspond to the low and high tube voltages. Its high temporal resolution and its suitability to a variety of source trajectories make it an attractive option for dual energy data acquisition. Its disadvantages include a one-view misregistration between the data for high and low voltages, the potentially poor spectrum separation due to the more-like a sine wave rather than the desired square wave in fast kV-switching, and the higher noise in the low voltage data because of the technical difficulty in swinging the tube current to counter the loss of x-ray production efficiency and loss of penetration at lower tube voltages.Type: GrantFiled: January 28, 2009Date of Patent: April 24, 2012Assignees: Kabushiki Kaisha Toshiba, Toshiba Medical Systems CorporationInventor: Yu Zou
