Abstract: A method for characterizing tissue of a patient, including receiving acoustic data derived from the interaction between the tissue and the acoustic waves irradiating the tissue; generating a morphology rendering of the tissue from the acoustic data, in which the rendering represents at least one biomechanical property of the tissue; determining a prognostic parameter for a region of interest in the rendering, in which the prognostic parameter incorporates the biomechanical property; and analyzing the prognostic parameter to characterize the region of interest. In some embodiment, the method further includes introducing a contrast agent into the tissue; generating a set of enhanced morphology renderings of the tissue after introducing the contrast agent; determining an enhanced prognostic parameter from the enhanced morphology renderings; and analyzing the enhanced prognostic parameter.

Abstract: A method and system for denoising acoustic travel times and imaging a volume of tissue comprising receiving a dataset representative of acoustic waveforms originating from an array of ultrasound emitters and received with an array of ultrasound receivers; for each ultrasound emitter in the array of ultrasound emitters, forming an empirical relative travel time matrix, from the dataset, including a set of relative empirical travel times, each relative empirical travel time corresponding to a pair of ultrasound receivers receiving an acoustic waveform, generating a denoised empirical relative travel time matrix, and extracting a set of denoised absolute travel times from the denoised empirical relative travel time matrix; and rendering an image of the volume of tissue based on an acoustomechanical parameter and the set of denoised absolute travel times corresponding to each ultrasound emitter in the array of ultrasound emitters.

Abstract: A system and method for imaging a volume of tissue comprising: a modular transducer array, configured to substantially surround the volume of tissue, emit acoustic waveforms toward the volume of tissue, and receive acoustic waveforms scattered by the volume of tissue, comprising a first and a second modular transducer subarray configured to couple to one another; a controller configured to control acoustic signals emitted by the first and the second modular transducer subarrays; an electronic subsystem, coupled to the modular transducer array, comprising a multiplexor and beam-forming elements and configured to receive a set of acoustic data from the first and the second modular transducer subarrays; and a processor configured to analyze the set of acoustic data, determine the distribution of at least one acoustomechanical parameter within the volume of tissue, and render an image of the volume of tissue based on the acoustomechanical parameter.
