Abstract: Described is a method for providing positioning suggestions to the user of a physiological sensor and a kit for configuring an ultrasound system to provide positioning suggestions. The method includes steps of receiving an ultrasound image from an ultrasound probe, processing the ultrasound image to identify a set of features, determining from the set of features whether the ultrasound probe is correctly aligned, and determining an action suggestion to be given to a user of the ultrasound probe to improve its alignment. The kit includes a display monitor and a real-time video processor for interfacing with the ultrasound system to receive an ultrasound image from an ultrasound probe, process the ultrasound image to determine a set of positioning information, produce a set of positioning suggestion information for adjusting the positioning of the ultrasound probe, and transmit the set of positioning suggestion information to the display monitor for display.

Abstract: A system and method for producing high resolution diffusion information and imaging from a subject. In some aspects, the method includes receiving a plurality of low resolution diffusion images, each acquired with a different set of gradient directions and shifted in a slice direction, and generating a model correlating diffusion signals associated with the plurality of low resolution diffusion images and a high resolution diffusion image. The method also includes reconstructing the high resolution diffusion image by minimizing a cost function determined using the model. In some applications, the method further includes processing the high resolution diffusion image to generate a report providing diffusion information associated with the subject.

Abstract: Methods and associated apparatuses for imaging a target. An echo sequence image of the target is acquired and a log spectrum of at least a portion of the echo sequence image is computed. A point spread function is estimated by one of two methods. According to the first method, a low-resolution wavelet projection of the echo sequence log spectrum is used as an estimate of the log spectrum of the point spread function. According to the second method, an outlier-resistant wavelet transform of the echo sequence log spectrum is effected, followed by soft-thresholding and an inverse wavelet transform. Under both methods, a frequency domain phase of the point spread function also is estimated, the relevant portion of the echo sequence image is deconvolved using the estimated point spread function.
