SYSTEMS AND METHODS FOR SYNTHETIC APERTURE ULTRASOUND TOMOGRAPHY

摘要

Synthetic-aperture ultrasound tomography systems and methods using scanning arrays and algorithms configured to simultaneously acquire ultrasound transmission and reflection data, and process the data for improved ultrasound tomography imaging.

主权项

1. A synthetic aperture ultrasound tomography imaging system for imaging a tissue medium, comprising:
one or more ultrasound transducer arrays; the one or more ultrasound transducer arrays comprising a plurality of transducers; wherein the plurality of transducers are configured such that a first set of two or more transducers are positioned at an opposing spaced-apart orientation from a second set of two or more transducers such that the first set of two or more transducers face the second set of two or more transducers; wherein the first and second sets of two or more transducers are positioned at spaced-apart locations so as to allow for the tissue medium to be positioned in between the first and second sets of two or more transducers; a processor; and programming executable on said processor and configured for:
exciting a first transducer within the first set of two or more transducers to generate an ultrasound field within the tissue medium; andreceiving a transmission signal and a reflection signal from at least the second set of two or more transducers.
