Augmented reality (AR) is a technology that uses computer-generated virtual content e.g. image rendering that is superimposed onto the user’s real environment 1. This is in contrast to virtual reality (VR) whereby the user is immersed into a completely virtual setting 1.
Clinical applications
One example is the use of stereoscopic images that has been adopted not only by the entertainment sector due to its impressive user experience 2,3, but has proven to have many potential uses in medicine and education, including radiology and in particular interventional radiology and radiology training.
The potential to enhance radiology training using augmented reality has been demonstrated in studies.
One such example uses 3D images to allow radiology trainees to visualize complex anatomy, such as that of the inner ear 4. This novel approach to training, which would supplement traditional learning styles, gives learners a chance to further consolidate intricate concepts, and studies have exhibited increased learner engagement with these techniques 5.
Applications of augmented reality in the pre and peri-operative IR setting include fluoroscopic fusion imaging 6 and translation of CT images into a 3D model that can be projected onto a patient or surgical site in different applications such as endovascular aortic aneurysm repair 7.
These enable the operator to view deeper structures in real-time, allowing for more accurate procedure planning 8 and may also lead to a reduction in radiation and contrast exposure for patients intra-operatively 6.
