Patent number: 5170347Abstract: A system for three-dimensional diagnostic imaging generates a plurality of slice images of a specimen. A region of interest is selected from within a slice and is extrapolated to subsequent slices. A boundary indicative of a surface of interest is selected from within the region of interest to facilitate generation of an image representative of a three-dimensional surface of interest to be assembled from subsequent slices of the plurality. A viewing surface is defined in relation to a generated surface image which was selected from the boundary. A scaling means assigns a scaled gray level to the three-dimensional image to facilitate three-dimensional viewing of the object when it is projected on the viewing surface. Image information is selectably modified by data from the original slice images to add surface density visualization. Means is also provided to facilitate selective segmentation of a three-dimensional image along a plane or planes of interest.Type: GrantFiled: April 30, 1990Date of Patent: December 8, 1992Assignee: Picker International, Inc.Inventors: Heang K.

Patent number: 5113340Abstract: Improvements in a hand-held spelling machine increase the speed with which a query word is compared against the words in memory. One technique is to provide a look up table to encode all character sets of one or two letters into a coded string. Where the set of letters is three or more characters, a previously known algorithm is employed. Search of the memory is limited to only a few main branches of the tree. The limitation is a function of the first query word letter. The time it takes to calculate the similarity function is saved in two circumstances. When a similarity function is calculated at a particular level of the tree and found to be great enough so that there is no prune of the tree, then that decision not to prune is carried forward for other tree branches having the same letters prior to the level involved.Type: GrantFiled: May 25, 1988Date of Patent: May 12, 1992Assignee: Franklin Electronic Publishers, IncorporatedInventor: David McWherter

Patent number: 5095432Abstract: A context-free parsing algorithm employing register vector grammars provides fast parsing of natural languages. A compiler for register vector grammars accepts input grammars as standard phase structure rules and generates strongly equivalent grammars in register vector grammar form. By applying the context-free register vector grammar parsing algorithm to the resulting grammars, strings may be parsed and trees may be constructed in the same manner performed with phase structure grammar.Type: GrantFiled: July 10, 1989Date of Patent: March 10, 1992Assignee: Harris CorporationInventor: Jonathan H.

Patent number: 5081581Abstract: A system for removing the effects of Compton scattering in systems such as tomographic scanning and radioisotope imaging arrangements, which detect gamma rays, utilizes the smoothness of the Compton component over the image to reduce computing time. Data responsive to energy states of the photons which are detected are received and values corresponding thereto are stored in at least one memory location. In some embodiments, where imaging is the ultimate function of the gamma ray detection system, the data correspond to predetermined image grid points. Also, the data which is stored is processed so as to be separated into a first data set corresponding to unscattered ones of the detected photons and a second data set corresponding to scattered ones of the detected photons. The gamma ray detection arrangement is calibrated by acquiring a spectral shape corresponding to unscattered photons. The processing utilizes non-linear least squares fitting analysis.Type: GrantFiled: March 31, 1989Date of Patent: January 14, 1992Assignee: The University of MichiganInventors: Kenneth F. Koral, W.

Patent number: 5070455Abstract: An imaging system generates images of the interior of an object using radiation which is attenuated and scattered by the interior of the object. The object is radiated at a number of points near the exterior of the object, and the radiation emerging from the object is measured at an array of exit points near the exterior of the object. The interior of the object is modelled as an array of volume elements called voxels. Each voxel is modelled as having scattering and attenuation properties, represented by numerical coefficients. The system computes the intensity of radiation that would emerge from the object at the exit points if the interior of the object were characterized by a currently assigned set of values for the scattering and attenuation coefficients. Then, the differences between the measured intensities and the computer intensities are used to compute an error function relates to the magnitude of the errors in the reconstruction.Type: GrantFiled: November 22, 1989Date of Patent: December 3, 1991Assignee: Singer Imaging, Inc.Inventors: Jerome R.

Patent number: 5070454Abstract: An object is exposed to penetrating radiation at each of a plurality of partial rotations of the object. Radiation transmitted through the object strikes a separate sheet of radiographic film for each exposure to record an entire radiographic image of the object for each angular orientation. At least two reference markers for providing a reference relative to the object are positioned between a rotating device and the sheet of radiographic film. They are positioned so that their centers constitute the base points of an equilateral triangle, the apex point thereof being the center of the rotating device.Type: GrantFiled: April 30, 1990Date of Patent: December 3, 1991Assignee: Olganix CorporationInventor: Lionell K.

Patent number: 5070502Abstract: It is desirable to bypass the defects within a cache memory so that a high percentage of the cache is usable; otherwise the entire chip containing the cache memory must be scrapped. Since VLSI chips with a small number of defects form a large proportion of the scrapped yield, rendering chips with a small number of defects usable greatly increases the production yield and reduces the cost of each chip. Therefore, a cache memory is provided wherein each memory location includes a bit which is set in response to a detected hardware defect. Preferably, each memory location in the cache is tested by error detecting software, which sets the defect bit in any memory location containing a defect. The defect bit is tested every time data is retrieved from each memory location, and a set defect bit prohibits further use of a defective memory location.Type: GrantFiled: June 23, 1989Date of Patent: December 3, 1991Assignee: Digital Equipment CorporationInventor: Robert M. Supnik

Patent number: 5063507Abstract: A commodity trading system having a centralized computer and data base. Each commodity, such as a bale of cotton, is represented in the data base as a file having all the information unique to such bale, including a title flag.
