Abstract: In some embodiments, a model (such as a formulaic model or machine-learning model) is used to predict adverse patient events. The model is developed based on patient data derived by monitoring patients of a patient population over a period of time, such as one year. Patient parameters, such as heart rate, are obtained from the patient data. Selected patient parameters and verified occurrences of the adverse patient events are used to develop the model to have a specified sensitivity and/or specificity. Key patient parameters, determined through analysis of the patient to have higher predictive power, are used to increase the sensitivity and/or specificity of the model. Once developed, new patients are monitored and corresponding patient parameters are obtained for the new patients. The model is then able to predict if one of the new patients will have an adverse patient event.

Abstract: Method and systems provide a tool to quantify sensory maps of the brain. Cortical surfaces are conformally mapped to a topological disk where local geometry structures are well preserved. Retinotopy data are smoothed on the disk domain to generate a curve that best fits the retinotopy data and eliminates noisy outliers. A Beltrami coefficient map is obtained, which provides an intrinsic conformality measure that is sensitive to local changes on the surface of interest. The Beltrami coefficient map represents a function where the input domain is locations in the visual field and the output is a complex distortion measure at these locations. This function is also invertible. Given the boundaries and the Beltrami map of a flattened cortical region, a corresponding visual field can be reconstructed. The Beltrami coefficient map allows visualization and comparison of retinotopic map properties across subjects in the common visual field space.
