Dr. Jeremy Dahl's laboratory develops ultrasonic beamforming and image reconstruction methods. A current focus in the lab is the development of methods that improve the quality of ultrasound images in the difficult-to-image patient population. For example, the Dahl Lab has developed a differentiable beamforming technique that estimates the local sound speed to correct for distortion in the ultrasound image. They have also adapted the differentiable beamformer to solve other problems in ultrasound imaging, such as estimation of the array shape for flexible ultrasound arryas. Often, they attempt to build these imaging methods into real-time imaging systems in order to apply them to clinical applications. Another focus of Dr. Dahl's laboratory is ultrasound molecular imaging, where they use targeted microbubbles to image the molecular signatures of disease. In this project, they have developed nondestructive real-time molecular imaging techniques alongside unique targeted contrast agents for the purpose of early detection of cancer and other diseases. Other small projects in the lab often involve ultrasonic beamforming and image reconstruction in new ways to enhance other areas of ultrasound research, such as drug delivery and passive cavitation mapping.
