Augmented Reality For MRI-Guided Interventions

Augmented Reality Real-Time Guidance for MRI-Guided Interventions

The purpose of this study is to determine feasibility and safety of using an augmented reality system in patients undergoing MRI-Guided needle procedures.

Study Overview

• Status: Recruiting
• Conditions: Infections; Pain; Diagnosis
• Intervention / Treatment: Device: Augmented Reality System

Detailed Description

This pilot clinical study is designed to evaluate the feasibility of using a needle guidance system during MRI-guided procedures in up to 12 patients. The MRI-compatible needle guidance system was developed under an NIH funded SBIR Phase II grant. This system has been evaluated by our Interventional Radiology team in phantom, volunteer, and cadaver studies which showed potential benefit of use in patients. Inclusion of the needle guidance system will not change the standard of care or substantively affect procedural technique as currently performed. This system provides the operator with an augmented reality (AR) display to better visualize the needle entry point and trajectory as it is inserted toward the target. This additional information could improve needle placement accuracy and shorten procedural time.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Patients Undergoing Augmented Reality Image-Guided Needle Procedures; Patients will undergo their standard of care image-guided needle biopsy, aspiration, or injection with the Augmented Reality system. Patients will be monitored for adverse events for two weeks following their procedure.	Device: Augmented Reality System; Subjects will undergo image guided needle aspiration, injection, or biopsy facilitated by the Augmented Reality system. The Augmented Reality guidance system will be operated by the interventional radiologist in the MRI suite.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Feasibility is measured by successful completion of greater than 80% of cases using the augmented reality needle guidance system.	1 day
Safety of using the augmented reality needle guidance system will be evaluated through assessment of procedure related adverse events that occur within 7 days of the procedure.	7 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Procedure time	Total procedure time.	1 day
Number of MRI scans	Number of MRI scans needed to complete the procedure, and size and depth of target will be recorded.	1 day
Clinical impressions of the system use and utility	The operator will complete a usability form that captures ease of use using the Likert scale.	1 Day
