Equipped with advanced tools, our MMR-Lab empowers unique and innovative research for patient care. We have the following devices:
Introducing our cutting-edge 3D scanning technology: Artec Leo and Autoscan Inspec. Artec Leo is a handheld scanner known for its ease of use and real-time capabilities, allowing you to quickly capture detailed 3D models with high precision. It’s perfect for scanning large objects like limbs or even entire rooms.
Autoscan Inspec, on the other hand, is a tabletop scanner designed for industrial quality control and inspection. With its high-precision scanning capabilities, it ensures accurate measurements and analysis of complex and small surgical instruments, such as tweezers, scissors, or blades.
Both scanners use structured light technology, making them safe to use on human subjects. Additionally, we provide 3D scanning spray for highly reflective and shiny objects to optimize surface scan quality. Experience the power of our advanced 3D scanning technology today.
Introducing the SLA Resin Creality Printer, built with advanced Stereolithography additive (SLA) printing technology, this printer offers exceptional precisn and detail in creating high-quality 3D models. Stereolithography (SLA) is an additive manufacturing process utilizing UV light to selectively harden the resin layer-by-layer and can print parts with small features, tight tolerance requirements, and smooth surface finishes. This printer allows us to make replicates of our 3D structured light scanned objects, CTA/MRI based surface models, Manually created cutting guides or AI generated patient specific implants. This allows us to bring our ideas to life accurately and within days. For even more rapid prototyping we plan to permanently install an FDM printer as well.
Our MMR Lab provides a wide range of cutting-edge mixed reality devices to enhance your experience in multi-user applications. In our lab, we offer various mixed reality devices, each with its unique capabilities. Mixed reality entails the fusion of the real and virtual worlds, achieved through two approaches: immersive optical-pass-through (mixed reality) and optical-see-through (augmented reality). By seamlessly combining real and virtual elements, mixed reality takes us beyond the capabilities of virtual reality.
Our lab features the HTC VIVE Pro 1 and 2, which utilize base station infrared scanners for user tracking, while the head-mounted display (HMD) captures the surrounding environment. These devices allow for superimposing filmed and registered reality onto the virtual world. For an even more immersive experience, we offer the high-end Varjo XR3 mixed reality device. Unlike other devices, the XR3 does not require a base station and also incorporates hand tracking technology, providing an unparalleled blend of both realities.
Additionally, we have 10 HoloLens 2 (HL2) devices, which offer optical-see-through functionality. With HL2, users experience minimal discomfort typically associated with mixed reality devices, as the real world is still perceptible through their eyes. These wireless devices include hand tracking, simultaneous localization and mapping technology, and an onboard computer, ensuring a seamless integration of both worlds.
At our MMR Lab, we strive to provide you with the latest mixed reality devices to enrich your view and unlock limitless possibilities for medical research and development.
Our Mixed Reality Lab is proud to offer the NDI Aurora and 3D Guidance trakSTAR systems, capable of generating an electromagnetic field and measuring changes within this field, thereby proving 3D tracking of devices based on these changes. These cutting-edge tracking solutions are designed to revolutionize the way medical instruments are tracked and visualized in real time, now also in 3D at our MMR lab. The Aurora and 3D Guidance trakSTAR electromagnetic tracking solution provides seamless and real-time tracking of micro sensors embedded in a wide range of medical instruments, including ultrasound probes, endoscopes, catheters, guidewires, and even the tip of a needle, enabling precise tracking of instruments through complex anatomical structures. When integrated into original equipment manufacturer image-guided surgery or interventional systems, the Aurora acts as a vital link between patient image sets and the 3D space. It instantly localizes the relative positions and orientations of instruments within the operative field. Enhance your mixed reality projects with unparalleled tracking capabilities and take your medical simulations and interventions to the next level. We plan on incorporating the devices with our mixed and augmented reality devices, frequent use for assesment of stand alone tracking systems and to seamlessly intertwine our research with the latest hospital standards.

Projects come to life with the help of our phantoms. These models serve as the foundation for developing, training, and showcasing our innovations. With our 3D printers, we can create (miniature) models for our research. However, we frequently use our larger-scale Karstadt models, Ms. and Mr. White, as well as our high-end cranio-maxillofacial surgery phantom from GTsimulators. These phantoms provide an invaluable platform for developing and demonstrating our medical Mixed Reality.
To further elevate our research, both Mr. White and our surgery phantom have undergone high-dose CT scans, enabling us to add a medical component to our Mixed Reality.Looking ahead, we are committed to expanding our repertoire of phantoms, particularly in the realm of ultrasound applications. By integrating these accurate phantoms with our Mixed Reality devices and tracking systems, we can unlock new dimensions of interactive exploration, enhanced visualization, and innovative medical solutions.
Some of our current projects involve markerless patient registration, 3D visualization of CT data and models directly within the patient, multi-user learning experiences, 3D databases (some of which are publicly available at https://medshapenet.ikim.nrw), inside-out tracking of patient and surgical instruments, and ongoing work on an augmented reality-assisted US-scanning approach with artificial intelligence support. Our vision encompasses a promising future where we bring visibility to the previously imperceptible, illuminating the unseen.
While we cannot showcase all our current projects online, we are excited to share a glimpse into our work.
This AR technique enables direct visualization of CT data and models within the patient, facilitating the translation from 2D CT slices to a 3D representation for enhanced diagnosis and treatment planning.
We have developed an automated markerless registration method for seamlessly integrating CT data and segmented models into the patient. This method addresses the switching focus problem, providing surgeons with direct 2D to 3D mapping of CT data and enabling surgical navigation in a cost-effective manner.
Using the sensors of the HoloLens 2, we have achieved highly accurate instrument tracking through infrared reflective markers. By combining this technology with our previous advancements, we offer an out-of-the-box solution for surgical navigation, eliminating the need for additional expensive equipment. An intersting follow up research would be the less acurate but intersting free form segmentation and tracking, i.e., without the need of infrared reflective markers.
Collaborative learning takes center stage in our research, as we create immersive multi-user experiences that foster interactive education and training for medical students. It could also be leveraged to enable multidisciplinary teams to discuss a patient’s treatment plan, without the need to be in the same room.
With our structured light 3D scanners, namely the Artec Leo and Autoscan Inspec, we have scanned over 100 instruments commonly used in clinical routines. This extensive collection serves various purposes, including general instrument detection and tracking in operating room settings, as well as medical simulation or training scenarios in virtual reality and mixed reality. These surface models can be enhanced to achieve realism using shaders available in popular game engines like Unity3D or through 3D modeling software such as Blender.
