Abstract: Methods and systems for automatically generating a severity index for images of anatomical features of a patient are provided. In an exemplary embodiment, an image of an anatomical feature of a patient is compared with a normal, standardized image of the same anatomical feature. Based on this comparison, a deviation image for the anatomical feature is generated that represents the degree and manner the acquired image deviates from normal for that anatomical feature. The deviation image is automatically pattern matched against multiple images of known disease severity for the anatomical feature. Based on the automated pattern match, a known disease severity, such as in the form of a severity index, is provided as corresponding anatomical feature for the patient.

Abstract: A technique for selecting portions of a dynamic medical image data set to be stored and portions of the medical image data set to be discarded or processed differently in order to reduce the overall amount of image data that is stored for each image data set. The dynamic image data is segmented and registered. The segmentation and registration enables changes in intensity based on patient motion to be distinguished from changes in intensity due to anatomical function. In general, the regions with changes in intensity due to anatomical function are more relevant than regions with changes in intensity due to patient motion. The regions of greatest relevance are stored at their full resolution. Regions of lesser relevance are stored at less than the full resolution. Regions of no relevance are discarded and not stored at all.

Abstract: Systems and methods are disclosed for modifying soft-programming trims of a non-volatile memory device, such as a flash memory device. The soft-programming trims may be modified based on a count of erase pulses applied to memory cells of the memory device. The number of erase pulses used to erase memory cells may be indicative of accumulated charge in the memory cell. The start voltage, step size, pulse width, number of pulses, pulse ramp, ramp rate, or any other trim of the soft-programming operation may be modified in response to the number of erase pulses.

Abstract: A fuel usage monitoring system, in certain aspects, may be configured to determine the fuel usage rate of a work vehicle service pack engine using control signals relating to operating parameters of the service pack engine and associated equipment. In certain embodiments, the control signals may relate to operating parameters of the engine, a fuel injection pump associated with the engine, a governor associated with the fuel injection pump, a fuel reservoir associated with the engine, and other components associated with the engine. In particular, the control signals may relate a position of a control rack of the fuel injection pump. The control signals may be correlated with fuel usage rates prior to operation of the fuel usage monitoring system. In addition, the correlations may vary as certain parameters of the engine, such as operating speed, vary. The correlations may be implemented as algorithms within software of the fuel usage monitoring system.
