“…This enabled estimation and compensation of tissue motion even when outside of the camera's FOV. Based on this work, Mountney and Yang [109] implemented an AR framework for soft tissue surgery that used intra-operative cone beam CT and fluoroscopy as bridging modalities to register pre-operative CT images to stereo laparoscopic images through non-rigid biomechanically driven registration. In this way, manual alignment or fiducial markers were not required and tissue deformation caused by insufflation and respiration during MIS was taken into account.…”

Mixed Reality (MR) is of increasing interest within technologydriven modern medicine but is not yet used in everyday practice. This situation is changing rapidly, however, and this paper explores the emergence of MR technology and the importance of its utility within medical applications. A classification of medical MR has been obtained by applying an unbiased text mining method to a database of 1,403 relevant research papers published over the last two decades. The classification results reveal a taxonomy for the development of medical MR research during this period as well as suggesting future trends. We then use the classification to analyse the technology and applications developed in the last five years. Our objective is to aid researchers to focus on the areas where technology advancements in medical MR are most needed, as well as providing medical practitioners with a useful source of reference.

“…Several authors, 6,7 have examined using intra-operatively digitised surfaces to drive biomechanical model based deformation of the liver. Mountney et al 8 propose using intra-operative cone beam CT to drive a biomechanically informed non rigid registration. They further refine the registration using intra-operative landmarks acquired using simultaneous localisation and mapping (SLAM).…”

We present an analysis of the registration component of a proposed image guidance system for image guided liver surgery, using contrast enhanced CT. The analysis is performed on a visually realistic liver phantom and in-vivo porcine data. A robust registration process that can be deployed clinically is a key component of any image guided surgery system. It is also essential that the accuracy of the registration can be quantified and communicated to the surgeon. We summarise the proposed guidance system and discuss its clinical feasibility. The registration combines an intuitive manual alignment stage, surface reconstruction from a tracked stereo laparoscope and a rigid iterative closest point registration to register the intra-operative liver surface to the liver surface derived from CT. Testing of the system on a liver phantom shows that subsurface landmarks can be localised to an accuracy of 2.9 mm RMS. Testing during five porcine liver surgeries demonstrated that registration can be performed during surgery, with an error of less than 10 mm RMS for multiple surface landmarks.

Recent developments in virtual, augmented, and mixed reality have introduced a considerable number of new devices into the consumer market. This momentum is also affecting the medical and health care sector. Although many of the theoretical and practical foundations of virtual reality (VR) were already researched and experienced in the 1980s, the vastly improved features of displays, sensors, interactivity, and computing power currently available in devices offer a new field of applications to the medical sector and also to urology in particular. The purpose of this review article is to review the extent to which VR technology has already influenced certain aspects of medicine, the applications that are currently in use in urology, and the future development trends that could be expected.
