Baltimore-based Sonavex develops automated 3D ultrasound solutions for dialysis access care, helping clinicians visualize and quantify vascular anatomy during fistula maturation and cannulation. Its physician-supported technologies include the EchoMark and EchoSure system for measuring fistula flow, diameter and depth, and EchoMap for showing vessel path and depth without requiring prior ultrasound experience. The multidisciplinary team brings together surgeons, scientists, technologists and business leaders, with research supported by federal and state agencies.
