Implantable Device for Spinal Cord Injury

Graphic: Haley Abramson

The HEPIUS Lab includes team members from the JHU School of Medicine, School of Engineering, Applied Physics Lab, and multiple companies. Together, we are creating a system of interactive devices based on ultrasound technology for continuous and active monitoring of patients with spinal cord injury. My contribution is to enable automated calculation of blood perfusion at the injury site.

Rapid, Intraoperative Foreign Body Object Detection

Figure source: Laura Roy

Leaving behind surgical items in the body burdens both patients and hospitals with millions of dollars spent every year. In this study, we have explored the powerful combination of deep learning, intraoperative ultrasound imaging and app development to demonstrate, in both animal and human studies, the ability to automatically detect and localize foreign body objects in neurosurgery.

Segmenting the left ventricle myocardium is a critical first step to analyzing heart pathologies. We developed a deep learning segmentation algorithm tailored to clinical application. This work out of the Trayanova Lab at JHU has been published in the Cardiovascular Digital Health Journal and was selected for poster presentation at the 2020 American Heart Association Conference.
