The USAMRDC project is divided into three Phases. In Phase 0, initiated in September 2023 and completed in June 2024, MAUI documented the baseline imaging performance of the system for more than 60 discreet anatomic regions, including intracranial and spinal imaging, needed for whole body trauma evaluations. No other ultrasound system is capable of imaging all of these regions. Phase 1 of the USAMRDC project will be focused on developing the procedures and techniques for using MAUI to image these 60 anatomic regions in a standardized fashion. Phase 2 will be focused on comparative imaging of actual trauma pathology in the Emergency Department.

A committee of independent expert physicians reported that MAUI can image comparably, or better than traditional ultrasound in areas where traditional ultrasound is used. In certain cases, like cranial and spinal imaging in adults, where traditional ultrasound has not been employed, MAUI has been reported to provide clinically meaningful images needed by physicians to diagnose, triage, and treat serious injuries.


Traditional ultrasound cannot image intracranially without a significant "window" into the skull involving large fractures or surgically removed bone. As a result, patients require CT or MRI scans which are often unavailable. MAUI is designed to change this and aims to decrease time to diagnosis and treatment.

"Trauma remains a major cause of death for individuals of all ages, both in civilian and military settings," said Rosemary Kozar MD, PhD, Professor of Surgery, Co-Director of Shock Trauma Anesthesia Research (STAR) Center, University of Maryland School of Medicine. "The ability to rapidly evaluate trauma without the need for immediate access to X-ray, CT and MRI facilities would be of tremendous value to trauma victims worldwide who have sustained significant injury. MAUI could be game changing in a mass casualty setting, underdeveloped countries and on the battlefield."

"The MAUI ultrasound technology and the K3900 offer a potentially significant advance in the triage, diagnosis and management of trauma in austere environments, i.e., on the battlefield, on naval vessels, on evacuation aircraft, in field hospitals, and more," Eric Elster, MD, FACS, FRCSEng (Hon.), CAPT, MC, USN (Ret.). "This technology could provide for the rapid evaluation of injured war fighters and civilians in conflict zones by first responders (medics and corpsmen), nurses, technicians, and physicians with minimal training, thereby improving clinical outcomes in resource-restricted environments. We look forward to the results of this research funded by the US Army Medical Research and Development Command."
