Quantitative Emboli Detection Using Nonlinear Ultrasound Technique, Phase I

We propose to develop a new and innovative method for the detection and classification of emboli flowing into the brain through Carotid arteries, specifically for situations involving space traveling. The present technique does not utilize Doppler technique, rather the advanced pulse-echo ultrasound technique based on detecting the nonlinear parametric scattered ultrasound pulse-echo wave from emboli. The proposed technique is predicted to have a resolution more than 10 times better than that of the Doppler technique, and to be able to exactly measure the size of and classify the type of emboli. Furthermore, the implementation of the proposed technique into a Holter-monitor type device is predicted to be much easier than the Doppler technique. This Phase I study propose to investigate the feasibility of the proposed technique in vitro.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
