Testing of a Transperineal Guide Grid for MR guided prostate procedures using Optical and Fiducial Fusion
PURPOSE: To describe the testing and feasibility of a transperineal guide grid based on optical fusion to aid in needle placement for biopsy and ablation. MATERIALS AND METHODS: The transperineal … Read more
A Novel Device for Training and Evaluating Ultrasound ‐Guided Procedures in Anesthesia
Currently, the method of evaluating a student’s skill is a professor’s observation of the student performing the intervention. The novel system developed here (EDU) provides quantitative metrics by continuously tracking … Read more
Augmented Reality Based Surgical Navigation of Complex Pelvic Osteotomies—A Feasibility Study on Cadavers
Augmented reality (AR)-based surgical navigation may offer new possibilities for safe and accurate surgical execution of complex osteotomies. In this study we investigated the feasibility of navigating the periacetabular osteotomy … Read more
Use of Computer-Assisted Instrument Guidance Technology by Student Registered Nurse Anesthetists for Simulated Invasive Procedures
This study was conducted to determine if computer-assisted instrument guidance (CAIG, Clear Guide Medical), with an optical tracking mechanism, enhances simulated transversus abdominis plane (TAP) block performance in a porcine … Read more
Computer-Assisted Needle Navigation for Pediatric Internal Jugular Central Venous Cannulation: A Feasibility Study
Vascular access for central venous catheter (CVC) placement is technically challenging in children. Ultrasound (US) guidance is recommended for pediatric CVC placement, yet many practitioners rely on imprecise anatomic landmark … Read more
Registration made easy – standalone orthopedic navigation with HoloLens
In surgical navigation, finding correspondence between preoperative plan and intraoperative anatomy, the so-called registration task, is imperative. One promising approach is to intraoperatively digitize anatomy and register it with the … Read more
New Ultrasound Technology Is a Useful Training Adjunct for Invasive Procedures
This study investigated computer-assisted instrument guidance as an educational tool for residents in a simulation environment. Primarily, the study evaluated residents’ procedural speed and accuracy using ultrasound with and without … Read more
Needle Guidance using Handheld Stereo Vision and Projection for Ultrasound-based Interventions
With real-time instrument tracking and in-situ guidance projection directly integrated in a handheld ultrasound imaging probe, needle-based interventions such as biopsies become much simpler to perform than with conventionally-navigated systems. … Read more
Conventional Versus Computer Assisted Stereoscopic Ultrasound Needle Guidance for Renal Access: A Randomized Bench-Top Crossover Trial
During urologic surgery,ultrasound (US) is an established method for needle guidance, butdifficulty in visualizing the needle trajectory may add technicalcomplexity to the procedure. Needle guidance systems may simplifythese procedures. The … Read more
