An ultrasound system employs an ultrasound probe (), a strain sensor () and a workstation (). The ultrasound probe () includes an ultrasound transducer for acquiring ultrasound images () of an anatomical region. The strain sensor () is arranged on the ultrasound probe () to measure a longitudinal strain applied by the anatomical region to the ultrasound probe () as the ultrasound transducer acquires ultrasound images () of the anatomical region. The strain sensor () encircles a longitudinal axis of the ultrasound probe () and is spaced from the ultrasound transducers relative to the longitudinal axis of the ultrasound probe (). The workstation () reconstructs an ultrasound volume () from the ultrasound images () acquired by ultrasound transducer, and responsive to the longitudinal strain measured by strain sensor (), determines an axial force and/ora bending force applied by the anatomical region to the ultrasound probe () as the ultrasound transducer acquires ultrasound images () of the anatomical region.

A mechanical ventilator () provides pressure support ventilation (PSV) to a patient (). A power of breathing (PoB) or work of breathing (WoB) estimator () generates a PoB or WoB signal () for the patient. An error calculator () computes an error signal as a difference between the PoB or WoB signal and a set point PoB or WoB value (). A controller () inputs a PSV control signal () equal to the product of the controller transfer function and the error signal to the mechanical ventilator. A patient adaptation component () fits parameters of a model of a controlled mechanical ventilation system comprising the mechanical ventilator and the patient to data comprising the PoB or WoB signal and the PSV control signal generated by the operating closed loop controller, and adjusts parameters of the controller transfer function to maintain stability of the operating closed loop controller.

This invention discloses a method and apparatus for managing lighting systems is disclosed. The method comprises performing a training phase for a plurality of settings wherein the training is represented by statistical parameters associated with a statistical model and then performing a monitoring phase to monitor the lighting system, determining whether characteristics of the monitored lighting system correspond to the model obtained during the training phase and determining an error exists when the monitored lighting system is not within tolerance values of the statistical parameters.

A method, system, and computer program product are provided for performing a multi-modal deformable imaging registration between two different modalities for which a functional dependency is missing or very difficult to identify. The method provides a nonlinear mapping between every pair of points in the two image modalities by calculating the nonlinear mapping for only a limited number of identifiable landmarks within the two modalities and a statistical deformation model of the structure of interest. The method comprises: calculating a mean deformation and a plurality of deformation mode Eigen vectors for a body structure from images from the same imaging mode with different deformation states for a plurality of subjects; performing a registration of a limited number of uniquely identifiable landmark points between images from two different imaging modalities for the same subject to calculate the deformation field for the landmarks from the images; determining weights for each deformation mode Eigen vector using deformation field values at the landmarks with the mean deformation and the deformation mode vectors; and summing the mean deformation field and the linear combination of the weighted deformation mode vectors to determine the deformation field between the different imaging modes for all the points within the images.
