Title:
New for Biomedical Ultrasound: Quantitative Imaging, Beamforming, and Devices
Abstract:
Biomedical ultrasound covers a wide range of topics from improving current imaging performance to developing new image modes, to the development of in body medical devices based on ultrasound communications and even to novel therapy approaches. This talk will discuss three research thrusts: quantitative imaging, beamforming for super resolution, and ultrasound-based in body devices. We will discuss work using quantitative ultrasound imaging techniques for identifying early response of breast cancer patients to neoadjuvant chemotherapy with a novel calibration procedure and how deep learning can be used to improve diagnostics and image reconstruction. Next, a novel nonlinear beamforming approach, called null subtraction imaging (NSI), will be presented. In this approach, images are constructed using the nulls in a beam pattern rather than the main lobe. This approach allows a removal of grating lobe artifacts and the production of super resolution microvessel images without a high computational burden or the use of contrast agents. The third thrust will demonstrate the superiority of ultrasound as a communication channel in soft tissues and one potential ultrasound-based device application. Specifically, we will discuss a novel electronic biopsy clip that is intended for use in tagging tissue for later surgical resection for breast cancer patients undergoing neoadjuvant chemotherapy. These biopsy clips will be powered by ultrasound, provide better visibility compared to passive biopsy markers, and can provide a unique identification tag or ultrasound identification (USID).
