Design and Implementation of Mobile Image Overlay System for Needle Interventions
نویسندگان
چکیده
BACKGROUND: Many medical procedures such as biopsies, spine injection, needle based aspirations, local ablation therapies are performed percutaneously (i.e., through the skin). A static [1] and adjustable [2] image overlay system was previously proposed to aid image-guided needle interventions. Increased calibration time, prone to misalignment, limited access around the patient, structural deformation and vibrations, and limited precise movement were the drawbacks associated with the previous systems. To overcome these limitations, we propose a mobile image overlay system of much lighter weight and smaller dimensions, as well significantly better image quality and intrinsic accuracy.

PURPOSE: Augmented reality systems have been proposed for image-guided needle interventions but they have not become widely used in clinical practice due to restrictions such as limited portability, low display refresh rates, and tedious calibration procedures. We propose a handheld tablet-based self-calibrating image overlay system. METHODS: A modular handheld augmented reality viewbox was con...

Introduction: MR guidance is being used for a host of spine injections and pain management procedures such as discography, periradicular nerve blocks, sympathetic blocks, celiac plexus blocks, sacroiliac joint injections, and facet (zygoapophysial) joint neurotomies. MR imaging provides exceptional depiction of the patho-anatomy in the vertebral column and intervertebral discs and also provides...
