Patent number: 8317518Abstract: Techniques for delivering medical care include receiving normal data that indicates normal conditions in a patient. Abnormality data is received and indicates an abnormal condition, if any, in a patient. An instance of a virtual patient is generated based on the normal data and the abnormality data. The instance includes a physiological component that describes a sufficiently comprehensive physical state of a patient having the abnormal condition to simulate clinical measurements of the patient's condition. The instance also includes a cognitive component that describes a patient's awareness of symptoms, history of behavior and ability to convey information in response to queries. Action data is received from a trainee. Response data is generated based on the action data and the instance. Display data is presented based on the response data, and indicates information about the instance available as a result of the requested action.Type: GrantFiled: February 7, 2007Date of Patent: November 27, 2012Assignees: University of Maryland, Baltimore, University of Maryland, Baltimore CountyInventors: Bruce Jarrell, Sergei Nirenburg, Marjorie Joan McShane, Stephen Beale

Patent number: 8313903Abstract: The invention is directed to binary oligonucleotide probes for nucleic analysis, which probes can be made of DNA or RNA that recognize nucleic acid analytes (both DNA and RNA) with unprecedented high selectivity under mild conditions and are highly sensitive to single nucleotide mismatches (SNP single nucleotide polymorphisms) without PCR amplification. In one group, the binary probes indicate that they have hybridized to a particular nucleic analyte by binding to a molecular beacon that gives off a fluorescent signal. A second group of binary probes bind to a dye such as malachite green, where upon hybridization to analyte the fluorescence of the dye increases dramatically and is easily detected and measured. The new binary probes require only about five minutes at room temperature to generate a detectable signal.Type: GrantFiled: April 1, 2007Date of Patent: November 20, 2012Assignee: The Trustees of Columbia University in the City of New YorkInventor: Dmitry Kolpashchikov

Patent number: 8207992Abstract: Medical imaging often involves the collective use of information presented in multiple images of an individual, such as images generated through different imaging modalities (X-ray, CT, PET, etc.) The use of a composite of these images may involve image registration to adjust for the variable position and orientation discrepancies of the individual during imaging. However, registration may be complicated by soft tissue deformation between images, and implementations (particularly pure software implementations) of the mathematical models used in image registration may be computationally complex and may require up to several hours. Hardware architectures are presented that apply the mathematical techniques in an accelerated manner, thereby providing near-realtime image registration that may be of particular use for the short timeframe requirements of surgical environments.Type: GrantFiled: December 5, 2008Date of Patent: June 26, 2012Assignee: University of Maryland, BaltimoreInventors: Raj Shekhar, Omkar Dandekar

Patent number: 8184033Abstract: Techniques for an analog-to-digital converter (ADC) using pipeline architecture includes a linearization technique for a spurious-free dynamic range (SFDR) over 80 deciBels. In some embodiments, sampling rates exceed a megahertz. According to a second approach, a switched-capacitor circuit is configured for correct operation in a high radiation environment. In one embodiment, the combination yields high fidelity ADC (>88 deciBel SFDR) while sampling at 5 megahertz sampling rates and consuming <60 milliWatts. Furthermore, even though it is manufactured in a commercial 0.25-?m CMOS technology (1 ?m=12?6 meters), it maintains this performance in harsh radiation environments. Specifically, the stated performance is sustained through a highest tested 2 megarad(Si) total dose, and the ADC displays no latchup up to a highest tested linear energy transfer of 63 million electron Volts square centimeters per milligram at elevated temperature (131 degrees C.) and supply (2.7 Volts, versus 2.5 Volts nominal).Type: GrantFiled: May 12, 2010Date of Patent: May 22, 2012Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Charles Chang-I Wang, Ivan Richard Linscott, Umran S.

Patent number: 8184129Abstract: Techniques for registration of multiple measurement modes of a body include receiving first and second data from different modes. Each includes measured values with coordinate values. For two mechanically aligned modes, any non-rigid registration is performed. For some modes, the non-rigid registration includes a coarse transformation and multiple fine scale transformations. The coarse transformation maximizes a coarse similarity measure. The second data is sub-divided into contiguous sub-regions. Fine transformations are determined between the sub-regions and corresponding portions of the first data to maximize a fine similarity measure. Sub-dividing and determining fine transformations repeats until stop conditions are satisfied. Transformations between the last-divided sub-regions are interpolated.Type: GrantFiled: August 30, 2011Date of Patent: May 22, 2012Assignees: University of Maryland, Baltimore, Cleveland Clinic FoundationInventors: Raj Shekhar, Vivek Walimbe

Patent number: 8180577Abstract: Techniques for determining effects on a biological system include determining rate constants for a particular time interval starting at an initial time. Each rate constant indicates a rate of transition from one of four states to a different one of the four states for a component of a biological system in presence of an external factor. A temporal change in a probability that the component is in a particular state after the initial time is determined without numerical iteration over multiple time steps. This includes determining three relaxation time constants that describe exponential changes based on the rate constants. The effect of the external factor on the biological system is determined based on the temporal change in the probability that the component is in the particular state. The probability at an arbitrary time is determined based on the rate constants and initial probabilities.Type: GrantFiled: December 17, 2010Date of Patent: May 15, 2012Assignee: University of Maryland, BaltimoreInventor: Lawrence Goldman

Also received is a region of interest that includes pixels that correspond to at least a portion of a meniscus of the knee. Without human intervention, a meniscus extraction threshold is determined based on pixel intensities in the region of interest. A meniscus object portion of the scan data is further determined without human intervention based on the meniscus extraction threshold and a geometrical constraint. Other techniques for automatically detecting meniscal tears includes receiving a meniscus object portion of scan data from a scanning device and receiving threshold data that indicates a meniscus extraction threshold. Without human intervention, a propensity for meniscal tears is determined based on the threshold data and the meniscus object portion of the scan data.Type: GrantFiled: August 12, 2008Date of Patent: May 15, 2012Assignees: University of Maryland, Baltimore, University of Maryland, Baltimore CountyInventors: Nabile Safdar, Bharath Ramakrishna, Chein-I Chang, Wei-min Liu, Khan Siddiqui, Eliot Siegel

Patent number: 8175808Abstract: Techniques for determining optimal duration for treatment of disease include receiving an untreated series of measurements and a treated series of measurements. The untreated series indicates temporal progression of a physical property related to a disease while the disease is untreated. The treated series of measurements indicates temporal progression of the physical property of the disease while a particular treatment is administered. A series of effectiveness values is determined based on the untreated and treated series. Each effectiveness value indicates a ratio between an untreated and a treated rate of change of the physical property at a corresponding time. An elapsed time is determined from start of treatment to an earliest time when an effectiveness value reaches an extreme compared to adjacent effectiveness values. Duration for treatment is based on the elapsed time, and is especially useful for each cycle of dose dense regimes for treatments with toxic side effects.Type: GrantFiled: March 20, 2006Date of Patent: May 8, 2012Assignee: Sloan Kettering Institute for Cancer ResearchInventor: Larry Norton
