Abstract
The potential that digital holographic imaging (DHI) holds in the future of radiology in 3D will undoubtedly lead to revolutionizing the guidance of minimally invasive surgical and percutaneous procedures, which are currently being performed using 2D and/or 3D images displayed on flat screens. This review will update the reader on the definition and processes of digital holography, holographic applications in radiology, limitations of holography and DHI and their significance in the future of radiology. Furthermore, the review elaborates upon the many open questions on how to exploit DHI fully in radiological practice.
