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. [ABSTRACT FROM AUTHOR]

In this paper, we present an exploratory study on the potential impact of holographic heart models and mixed reality technology on medical training, and in particular in teaching complex Congenital Heart Diseases (CHD) to medical students. Fifty-nine medical students were randomly allocated into three groups. Each participant in each group received a 30-minute lecture on a CHD condition interpretation and transcatheter treatment with different instructional tools. The participants of the first group attended a lecture in which traditional slides were projected onto a flat screen (group "regular slideware", RS). The second group was shown slides incorporating videos of holographic anatomical models (group "holographic videos", HV). Finally, those in the third group wore immersive, head-mounted devices (HMD) to interact directly with holographic anatomical models (group "mixed reality", MR). At the end of the lecture, the members of each group were asked to fill in a multiple-choice questionnaire aimed at evaluating their topic proficiency, as a proxy to evaluate the effectiveness of the training session (in terms of acquired notions); participants from group MR were also asked to fill in a questionnaire regarding the recommendability and usability of the MS Hololens HMDs, as a proxy of satisfaction regarding its use experience (UX). The findings show promising results for usability and user acceptance., (© 2023. The Author(s).)
