Holographic Techniques as a Novel Method for Intervention Planning: A Tertiary Centres Experience

Abstract

Advanced holographic visualization techniques are becoming increasingly important in clinical practice, not only for diagnostic purposes but also in the planning of interventional or surgical procedures. The traditional approach for visualizing anatomic structures is based on standard imaging modalities such as echocardiography, cardiac magnetic resonance (CMR) and cardiac CT scan (CCT) which, however, can only provide two-dimensional (2D) images thus limiting 3D perception. Many recent studies have shown that the use of 3D imaging modalities such as augmented reality, virtual reality, mixed reality and holography improve the short and long-term outcome of percutaneous or surgical procedures. In this article, we report our experience on the use of the hologram in different clinical scenarios and in the field of university education.
