==METHOD AND SYSTEM FOR NON-INVASIVELY CHARACTERISING A HETEROGENEOUS MEDIUM USING ULTRASOUND - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240032889 titled 'METHOD AND SYSTEM FOR NON-INVASIVELY CHARACTERISING A HETEROGENEOUS MEDIUM USING ULTRASOUND

==Simplified Explanation==

The abstract describes a method for non-invasively characterizing a heterogeneous medium using ultrasound. The method involves generating a series of incident ultrasonic waves and recording an experimental reflection matrix between the input emission basis and the output reception basis. The method also includes determining a response of the medium between an input virtual transducer and an output virtual transducer, calculated based on the input and output focusing of the experimental reflection matrix. The response is expressed as a function of a central point of spatial position in the medium located midway between the input and output focal spots.

* The method involves generating ultrasonic waves and recording the reflection matrix between input and output bases.
* The response of the medium is determined using virtual transducers calculated based on the focusing of the reflection matrix.
* The response is expressed as a function of the central point of spatial position in the medium.

Potential applications of this technology:
* Medical imaging: The method can be used for non-invasive imaging of heterogeneous tissues, allowing for better characterization of abnormalities or diseases.
* Material characterization: The method can be applied to analyze the properties of heterogeneous materials, such as composites or porous structures.

Problems solved by this technology:
* Non-invasive characterization: The method provides a non-invasive way to characterize heterogeneous mediums, eliminating the need for invasive procedures.
* Improved imaging resolution: By using virtual transducers and focusing techniques, the method allows for improved imaging resolution and localization of features within the medium.

Benefits of this technology:
* Non-invasiveness: The method offers a non-invasive alternative to traditional methods of characterizing heterogeneous mediums, reducing patient discomfort and risks associated with invasive procedures.
* Enhanced imaging capabilities: By utilizing virtual transducers and focusing techniques, the method enables higher resolution imaging, leading to improved diagnostic accuracy and treatment planning.
