Latest Patents

Chandraratna's latest patents include an ultrasound transducer device for continuous imaging of the heart. This innovative device is designed for diagnosing or monitoring patients by providing real-time imaging. It features a spherical transducer assembly that is held by a patch coated with adhesive for easy attachment to the patient's body. The device allows for manual adjustment of the transducer's orientation to optimize the scanned area. An alternate embodiment includes remote-controlled adjustment capabilities.

Another significant patent is the ultrasound microscope for imaging living tissues. This series of devices enables in vivo imaging of cellular architecture across various tissues. A 200 MHz transducer is mounted on the tip of medical instruments such as cardiac catheters and endoscopes. The transducer is mechanically moved to produce B-mode images of cells within the tissue. The ultrasound beam is focused on a subsurface region, and the backscattered ultrasound is analyzed to create detailed images. To address the challenges posed by heart motion during imaging, the system gates images in mid-diastole for cardiac applications.
