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

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 (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

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

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

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

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

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
