Jinyi Qi, a professor of biomedical engineering at UC Davis, and project scientist Xuezhu Zhang developed methods to reduce noise and reconstruct images from the data of the EXPLORER scans for the volunteer, capturing changes on a scale of 100 milliseconds, or one-tenth of a second to create high quality real-time movies of the scans.

The scan was conducted at United Health Imaging, which holds the rights to uEXPLORER, with Zhongshan Hospital in Shanghai supervising.

The researchers are continuing to capture images from volunteers at UC Davis, where an FDA-approved model was approved for clinical use in 2019. The project was supported with grants from the National Cancer Institute and National Institutes of Health.

"We will continue further methodological development to refine and validate our methods, and then would plan to work with our colleagues in cardiology to apply these methods in relevant patient populations," said Cherry. "But this will still take some time (1-2 years)."

The findings were published in the Proceedings of the National Academy of Sciences.
