Immersive VR, AR, MR, and holography surgical navigation using VR-HMD, VIVE, Oculus, Google Tango, zSpace, and HoloLens
Maki Sugimoto, MD. IUHW Graduate SchoolWe developed an integrated surgical navigation system of patient-based immersive virtual reality, holographic augmented reality, and mixed reality surgical navigation for laparoscopic surgery. At first, by reconstructing the patient-specific 3D surface models of each organ out of the patient’s MDCT images, immersive VR navigation system was developed using side-by side… Continue Reading
GPS Lap Ultrasound: Embedding Electromagnetic Sensing to Laparoscopic Ultrasound
Xinyang Liu, Timothy D Kane, Raj Shekhar. Children's National Health SystemObjective: Computer-assisted surgery (CAS) is increasingly an integral part of modern patient care. To enable CAS, it is important to localize imaging devices and surgical tools with respect to one another and the patient. This localization in the 3D space, referred to as tracking, is… Continue Reading
