Augmented reality-assisted surgery

Augmented reality-assisted surgery (ARAS) is surgical training tool utilizing technology that superimposes a computer-generated image on a surgeon’s view of the operative field, thus providing a composite view for the surgeon of the patient with a computer generated overlay enhancing the operative experience. ARAS can be performed using a wide array of technology, including an optical head-mounted display (OHMD)—such as the Google Glass XE 22.1 or Vuzix STAR 1200 XL[1]—and a digital overlay from robotic and laparoscopic surgery feeds.[2] The technique has been primarily been tested in the urological and cardiovascular domains.[1][3][4]

Specialized uses

A subset of ARAS called augmented reality-assisted urologic surgery (ARAUS) specifically aids with urological surgery. This intraoperative training tool was first described and utilized by Tariq S. Hakky, Ryan M. Dickey, and Larry I. Lipshultz within the Scott Department of Urology, Baylor College of Medicine, and Daniel R. Martinez, Rafael E. Carrion, and Philippe E. Spiess within the Sexual Medicine Program in the Department of Urology, at the University of South Florida.[1] It was initially used to teach medical residents how to place a penile prosthesis from start to finish via an application downloaded onto the OHMD. Intraoperatively, an optical display camera output feed combined with software allowing for the detection of points of interest enabled faculty to interact with residents during the placement of the penile prosthesis. Both faculty and residents demonstrated a high degree of satisfaction of the ARAUS experience, and it was shown to be an effective tool in training urological surgical technique. Advantages of ARAUS include real-time feedback of residents during surgery and superior visibility and interaction between faculty and residents.[1][3]

ARAS has also been applied to the cardiovascular realm. Terry Peters of the University of Western Ontario in London, Canada has teamed up with other researchers at the Robarts Research Institute to implement ARAS towards the goal of improving repairs to the heart's mitral valve and replacement of the aortic valve.[4] In an interview for the Medical Augmented Reality Blog, Peters stated that his research team could not only use ARAS to "[improve] the speed and safety of the cardiac valve repair procedure"; they also conducted "the evaluation of an AR environment to plan brain-tumor removal, and the development of an ARF-enhanced system for ultrasound-guided spinal injections."[5]
