AI Technical Summary

Benefits of technology

The present invention is a system and method that uses ultrasound data collected using a synthetic-aperture ultrasound system. This system can acquire each tomographic slice of patient ultrasound data in real-time, allowing for better accuracy and higher resolution images. The system uses a transducer array that simultaneously records ultrasound signals scattered from the tissue after each element is fired, resulting in a more accurate image while minimizing computational costs. Overall, the invention provides a real-time, high-resolution synthetic-aperture system for patient data acquisition.

Problems solved by technology

Ultrasound waveform tomography is gaining popularity, but is computationally expensive, even for today's fastest computers.
The computational cost increases linearly with the number of transmitting sources.
Accordingly, these systems suffer from extensive computational costs, insufficient resolution, or both.

Embodiment Construction

[0036]The description below is directed to synthetic aperture ultrasound tomography systems for imaging a medium such patient tissue, along with ultrasound waveform tomography methods for acquiring and processing data acquired from these systems, or other systems that may or may not be available in the art.

[0037]The synthetic-aperture breast ultrasound tomography system of the present invention uses synthetic-aperture ultrasound to obtain quantitative values of mechanical properties of breast tissues. In this system, each transducer element transmits ultrasound waves sequentially, and when an ultrasound transducer element transmits ultrasound waves propagating through the breast, all ultrasound transducer elements (at least within a portion of an array) simultaneously receive ultrasound reflection / transmission, or forward and backward scattering signals. The ultrasound reflection / transmission signals are used to obtain quantitative values of mechanical properties of tissue features ...
