Publication number: 20180154174Abstract: A method and system are provided. The method includes condensing, by a processor, an original voxel-beamlet matrix stored in a memory device into a reduced dataset for proton beam simulation and therapy. The original voxel-beamlet matrix has a row for each of a plurality of voxels in a three-dimensional patient volume and a column for each of a plurality of radiation beamlets. The condensing step includes determining protobeams to be extracted from the original voxel-beamlet matrix. The protobeams are columns (i) selected from the original voxel-beamlet matrix based on comparisons performed between the columns in the original voxel-beamlet matrix or (ii) created by combining at least some of the columns in the original voxel-beamlet matrix, in a matrix condensing process. The condensing step further includes extracting the protobeams from the original voxel-beamlet matrix. The condensing step also includes storing the protobeams as the reduced dataset in the memory device.Type: ApplicationFiled: December 6, 2016Publication date: June 7, 2018Inventors: ANNE E.

Patent number: 9987502Abstract: A method and system are provided. The method includes splitting, by a processor based on radiation beamlet contributions to neighboring voxels, at least one row in a voxel-beamlet matrix and corresponding elements of a target dose vector prior to, and in preparation for, a regression operation. The voxel-beamlet matrix has a row for each of a plurality of voxels in a three-dimensional patient volume and a column for each of a plurality of radiation beamlets. The target dose vector represents a desired energy amount for each of the plurality of voxels in the three-dimensional patient volume. The target dose vector corresponds voxel-by-voxel to rows in the voxel-beamlet matrix. The method further includes performing, by the processor, the regression operation on the voxel-beamlet matrix and target dose vector to obtain beamlet weights. The method also includes determining an actual radiation dosing scheme for a given patient based on the beamlet weights.Type: GrantFiled: December 6, 2016Date of Patent: June 5, 2018Assignee: International Business Machines CorporationInventors: Anne E.

Patent number: 9690774Abstract: An approach is provided that improves a question answering (QA) computer system by reducing a number of vague questions submitted to the QA system. When a question is submitted to the QA system, the approach performs a vagueness question analysis on the question. The vagueness question analysis results in a vagueness score. The question is submitted to the QA system in response to the vagueness score reaching a threshold value that indicates a lack of vagueness in the question. The approach inhibits submission of the question to the QA system in response to the vagueness score failing to reach the threshold value.Type: GrantFiled: December 16, 2015Date of Patent: June 27, 2017Assignee: International Business Machines CorporationInventors: William A. Beason, Vincent J. Dowling, Anne E. Gattiker, Lakshminarayanan Krishnamurthy, Joseph N. Kozhaya

Patent number: 7759960Abstract: Methods for testing a semiconductor circuit (10) including testing the circuit and modifying a well bias (14, 18) of the circuit during testing. The methods improve the resolution of voltage-based and IDDQ testing and diagnosis by modifying well bias during testing. In addition, the methods provide more efficient stresses during stress testing. The methods apply to ICs where the semiconductor well (wells and/or substrates) are wired separately from the chip VDD and GND, allowing for external control (40) of the well potentials during test. In general, the methods rely on using the well bias to change transistor threshold voltages.Type: GrantFiled: April 16, 2008Date of Patent: July 20, 2010Assignee: International Business Machines CorporationInventors: Anne E.

Patent number: 6618682Abstract: A method and system are provided that minimize wafer or package level test time without adversely impacting yields in downstream manufacturing processes or degrading outgoing quality levels. The method provides optimization by determining, a priority, the most effective set of tests for a given lot or wafer.
