Researchers have developed an augmented reality (AR) technique to visualize 3D virtual guidance lines directly on a patient during fluoroscopy-guided orthopedic surgery — reducing procedure time and radiation, according to a study published in the April 2018 issue of the Journal of Medical Imaging.
“Using a marker that is visible by the x-ray system and the head-mounted display, we can immerse the surgeon in an augmented reality environment in unprepared operating rooms,” co-author Mathias Unberath, PhD, told. “From a clinical perspective, our hope is that such less-intrusive systems will find broader application since their benefit is not outweighed by notable disruption of the surgical workflow.”
“Our recent research on medical augmented reality has focused on enabling this technology in the operating room without substantial changes to the clinical workflow,” he said. “We wanted to provide virtual content designated for procedural guidance at the surgical site to help hand-eye coordination in image-guided procedures, suggesting that we needed to somehow calibrate the AR display to the patient or images of the patient.”
