Four recently issued patents boost ultrasound scanners to detect obscured pathologies.
New technologies developed at the could soon help make ultrasound a more powerful tool for diagnosing cancer, liver disease, and other pathologies.
The United States Patent and Trademark Office recently issued four patents for diagnostic ultrasound technology developed by , the William F. May Professor of Engineering at the Universitys , and his doctoral students. Parker says some of the technologies have already been licensed to startups that want to bring the advances into clinics for the benefit of patients everywhere.
Many diseases, including some malignant cancers, can still be hiding or obscured in medical imaging, says Parker. There are many cases where youd like the picture to be crystal clear, but you cant really see it. So, we used advanced physics, math, and scattering theory to pull out the hidden features from ultrasound data that could indicate problems with organs such as the liver, thyroid, or breast.
Two of the patents are related to the developed in Parkers lab and the other two focus on reverberant shear wave fields.
H-scan takes a standard black-and-white ultrasound image and attributes colors to featuresfor example, coding fat accumulating in the liver as yellow or cancer appearing in the breast as red.

The technologies related to provide new capabilities for elastographydetecting the stiffness of tissue. Many pathologies change the tissue properties including stiffness, says Parker. If your liver is getting stiff its probably bad, if your brain is getting stiff, its not good, and many cancers show up as stiff lesions.
Parker says the technologies offer cheaper, faster, and better ways of getting the information to doctors and radiologists. And since his inventions focus on ultrasound image processing, they can be easily retrofitted to existing ultrasound equipment and do not require new hardware.
These are inventions that you can retrofit to existing imaging systems. You can reprogram the scanners to process our way and out comes this new analysis and information, says Parker. We dont have to recreate a whole new generation of ultrasound scanners.
Parker says some of his key collaborators included Juvenal Ormachea 19 PhD () and Jiyhe Baek 23 PhD (). He worked closely with UR Ventures, which protects, develops, and commercializes the intellectual property arising from research at the University, to secure the patents:
The research that led to the development of the H-scan patents was supported by the National Institutes of Health.
