Augmented reality system for MRI-guided interventions: a cadaver study
Implementation of MRI guidance in place of CT or X-ray would reduce ionizing radiation exposure and provide better soft tissue contrast in a wide range of musculoskeletal targets in children. … Read more
A Novel Device for Training and Evaluating Ultrasound-Guided Procedures in Anesthesia
To improve dynamic needle-tip visualization, nurse anesthesiology students were evaluated during simulated ultrasound-guided procedures. This quasiexperimental study utilized two computed tomography 3D printed models. Thirty-two students performed each procedure twice, … Read more
Clinical evaluation of a transperineal access tool for MRI guided procedures
PURPOSE: To present the preliminary results of a 30-patient clinical study evaluating a transperineal guidance system (Clear Guide SCENERGY TP) for MRI-guided procedures. MATERIALS AND METHODS: We utilized the SCENERGY … Read more
Development and Optimization of Clinical Workflow for MRI-guided Interventions with Augmented
Purpose: CT and X-ray imaging for needle guidance exposes patients and interventionalists to ionizing radiation and can increase risk of some forms of cancer. While ultrasound imaging offers a radiation-free … Read more
Design and evaluation of an educational device for ultrasound-guided interventional procedures
This paper presents the development and evaluation of an educational system for training and skills assessment of students performing ultrasound-guided interventional procedures. The system consists of: a needle guidance software … Read more
Wearable Mechatronic Ultrasound-integrated AR Navigation System for Lumbar Puncture Guidance
Abstract As one of the most commonly performed spinal interventions in routine clinical practice, lumbar punctures are usually done with only hand palpation and trial-and-error. Failures can prolong procedure time … Read more
In situ guidance for MRI interventions using projected feedback
Purpose To develop and evaluate an augmented reality instrument guidance system for MRI-guided needle placement procedures such as musculoskeletal biopsy and arthrography. Our system guides the physician to insert a … Read more
Evaluation of a perineal access device for MRI-guided prostate interventions
This paper describes a perineal access tool for MRI-guided prostate interventions and evaluates it using a phantom study. The development of this device has been driven by the clinical need … Read more
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
