A comprehensive study to learn the impact of augmented reality and haptic interaction in ultrasound-guided percutaneous liver biopsy training and education

Abstract

Simulation based training methods are gaining popularity as they could provide a platform for practitioners to gain hands-on experience without causing ethical issues. By combining augmented reality (AR) and haptics, a training method for percutaneous liver biopsy (PLB) could be developed providing realistic scenarios, and real-time visualization of the human anatomy and needle. Additionally, it could also provide real-time feedback to the practitioner. In this review, we describe the conventional PLB procedure, then discuss AR technology and its application in the field of medicine for image-guided therapies, especially, hepatic biopsy. Next, we summarize the associated devices, models and methods illustrating a few haptic simulators devised for training and gesture assessment. Lastly, we present a few potential approaches to integrate AR and haptic interaction to develop a PLB training simulator by accounting the existing challenges.
