Medical imaging quality and accuracy of the human body (MRI, CT-scan, US, PET-scan) currently enable practitioners to establish a very precise diagnosis and to plan surgical interventions (open and laparoscopic surgery). Additionally, from CT-scan or MRI sections, the latest systems allow to display organs and pathological structures of patients in 3 dimensions, thereby facilitating the spatial understanding of practitioners. However, fully exploiting this precious information remains a challenge. In this presentation, the author explains how 3D patient model can be used to improve surgical planning. The author then describes how these 3D models can be brought to the operating room using augmented reality. Finally, the author provides an overview of the latest techniques about augmented reality guidance during minimally invasive surgery, and the main problems that still need to be overcome.
