Development of a Head-Mounted Holographic Needle Guidance System for Enhanced Ultrasound-Guided Neuraxial Anesthesia: System Development and Observational Evaluation

Development of a Head-Mounted Holographic Needle Guidance System for Enhanced Ultrasound-Guided Neuraxial Anesthesia: System Development and Observational Evaluation

To enable the Holo Lens to detect the ultrasound transducer position, a quick response code optical tracking marker was developed (Figure 1). First, a high-resolution 3 D scan of a curvilinear ultrasound probe was carried out with an Ein Scan HX handheld 3 D scanner (SHINING 3 D Tech Co Ltd).

The Potential for Using Extended Reality Technology in Interdisciplinary Case Discussions and Case Planning in Stereotactic Radiosurgery: Proof-of-Concept Usability Study

The Potential for Using Extended Reality Technology in Interdisciplinary Case Discussions and Case Planning in Stereotactic Radiosurgery: Proof-of-Concept Usability Study

A commercially available XR headset, Microsoft Holo Lens, was used for the visualization and interaction with virtual holograms (Figure 1). The Holo Lens is a head-mounted display with video-transparent lenses and has an untethered and wireless design. Microsoft Holo Lens headset.

Using Mixed Reality Headsets to Deliver Remote Bedside Teaching During the COVID-19 Pandemic: Feasibility Trial of HoloLens 2

Using Mixed Reality Headsets to Deliver Remote Bedside Teaching During the COVID-19 Pandemic: Feasibility Trial of HoloLens 2

Holo Lens 2 is an MR head-mounted device developed and marketed by Microsoft Corp. The headset combines several types of sensors to provide a true “heads-up display” with the ability to place virtual “hologram” objects within the user’s visual field. It also permits live bidirectional communication via video, MR composites, and voice with multiple remote users.

Augmented Reality-Based Surgery on the Human Cadaver Using a New Generation of Optical Head-Mounted Displays: Development and Feasibility Study

Augmented Reality-Based Surgery on the Human Cadaver Using a New Generation of Optical Head-Mounted Displays: Development and Feasibility Study

(c-d) Photograph taken through Holo Lens as one of the investigators performs the cadaver trial. (c) The cadaver head is overlaid with the virtual bone model. The zygomatic arch is shown in green because the tip of the virtual Stromeyer hook has not yet collided with the intended position of the nonfractured zygomatic arch model. The Stromeyer hook is superimposed with an accurate virtual model of itself.

HoloLens-Based Vascular Localization System: Precision Evaluation Study With a Three-Dimensional Printed Model

HoloLens-Based Vascular Localization System: Precision Evaluation Study With a Three-Dimensional Printed Model

Holo Lens, developed by Microsoft Corporation, is considered a very suitable AR HMD for surgical practice [5]. When wearing Holo Lens, surgeons are able to see the AR images in a single view. Another key advantage of Holo Lens is that it is not only a display system but is also a self-contained computer equipped with a camera and sensors, thereby avoiding the need to install any other hardware to realize the AR effect, which could further help to reduce the risk of contamination in the operating room.
