20160089015 | METHOD FOR CORRECTING AN OCT IMAGE AND COMBINATION MICROSCOPE - A method for improving an OCT image of an object such as the retina of an eye, using optical coherence tomography by an imaging beam path. In order to suppress shadowing effects due to a surgical instrument moved in the imaging beam path, a time series of OCT images is produced. For an OCT image to be corrected, an area of the object lying in the image and shadowed by the instrument is determined. Another earlier OCT image in which the area of the object is not shadowed is searched in the time series. Image information for the area of the object is read from the earlier OCT image. A corrected OCT image is produced by inserting the read-image information into the OCT image to be corrected, wherein in the OCT image to be corrected, the image information replaces the area of the object which is shadowed by the instrument. | 03-31-2016 |

20130324842 | Method for Estimating Pressure Gradients and Fractional Flow Reserve from Computed Tomography Angiography: Transluminal Attenuation Flow Encoding - An embodiment in accordance with the present invention provides a method for non-invasively determining the functional severity of coronary artery stenosis. The method includes gathering patient-specific data related to concentration of a contrast agent within a coronary artery of a patient using a coronary computed tomography angiography scan (CCTA). The patient-specific data is used to calculate a patient-specific transarterial attenuation gradient for the coronary artery of the patient. The patient specific transarterial attenuation gradient is compared to previously collected data to determine an estimate of a pressure gradient and/or fractional flow reserve (FFR) for the patient. As more data is collected, the data can be added to the database in order to increase the accuracy of future assessments. The database can also be enhanced by adding data generated by canonical models and mathematical analysis. | 12-05-2013 |

20160104070 | INFERENCE ENGINE FOR EFFICIENT MACHINE LEARNING - An inference engine is described for efficient machine learning. For example, an inference engine executes a plurality of ordered steps to carry out inference on the basis of observed data. For each step, a plurality of inputs to the step are received. A predictor predicts an output of the step and computes uncertainty of the prediction. Either the predicted output or a known output is selected on the basis of the uncertainty. If the known output is selected, the known output is computed, (for example, using a resource intensive, accurate process). The predictor is retrained using the known output and the plurality of inputs of the step as training data. For example, computing the prediction is fast and efficient as compared with computing the known output. | 04-14-2016 |
