MR in OR: First analysis of AR/VR visualization in 100 intra-operative Freehand SPECT acquisitions

“…For example, when the users of an MARS observe the internal organs not usually visible to their eyes or hear the augmented sound of an organ touched by a surgical instrument, a perceptually consistent experience should be preferred, allowing the users to recognize and localize the objects otherwise invisible to the users’ unaided senses. Evidence that they can, in fact, integrate the additional information and are affected by the augmented visuals and sounds can be explored in experiments with users: For example, Okur et al [ 15 ] analyzed the surgeons’ visualization preference (either AR or VR) in intra-operative SPECT acquisitions. The surgeons relied on both AR and VR visualizations and stated that the two modes complemented each other.…”

“…With a successful AR system, users can use this information to improve their interaction with their natural environment. One example of the iterative inclusion of the user towards the development of a successful system is a project conducted within our lab that integrated VR and AR for intraoperative single-photon emission computerized tomography (SPECT), which was started in 2007 [ 28 ] and resulted in the first MARS used in surgery with CE certification and FDA clearance in 2011 [ 15 ].…”

Three decades after the first set of work on Medical Augmented Reality (MAR) was presented to the international community, and ten years after the deployment of the first MAR solutions into operating rooms, its exact definition, basic components, systematic design, and validation still lack a detailed discussion. This paper defines the basic components of any Augmented Reality (AR) solution and extends them to exemplary Medical Augmented Reality Systems (MARS). We use some of the original MARS applications developed at the Chair for Computer Aided Medical Procedures and deployed into medical schools for teaching anatomy and into operating rooms for telemedicine and surgical guidance throughout the last decades to identify the corresponding basic components. In this regard, the paper is not discussing all past or existing solutions but only aims at defining the principle components and discussing the particular domain modeling for MAR and its design-development-validation process, and providing exemplary cases through the past in-house developments of such solutions.

“…By tracking both the gamma probe and a positioning system fixed on the patient's body, this technique allows intraoperative 3D mixed reality-based navigation of the gamma probe to the lesion of interest, e.g., during SLN biopsy for breast cancer [75]. As well as allowing real-time acquisition of SPECT scans in the operating room, the system can also load preoperatively acquired SPECT/CT data.…”

Radioguided surgery (RGS) utilizes radiolabeled tracers that accumulate in the lesion of interest following local or systemic administration. RGS is an expanding surgical guidance technology, but unfortunately most currently available radiotracers are unable to provide intraoperative optical information regarding the location of the lesion. In 2011, a new hybrid tracer (both radioactive and fluorescent) was introduced for sentinel lymph node detection. This hybrid tracer (indocyanine green99m Tcnanocolloid) has helped to generate a new hybrid surgical guidance concept, thereby expanding the traditional RGSbased approach. Based on its radioactive signature a hybrid tracer is able to preserve the ''traditional'' role for RGS. Furthermore, as an additional tool in the operating room, a hybrid tracer provides optical information via fluorescence guidance. This review discusses the most common RGS approaches. Different clinically used radioactive tracers and their potential hybrid derivatives are also discussed. Furthermore, the various imaging devices designed for radioactivity-based detection are reviewed in the context of generating hybrid-imaging modalities.
