Navigation Environment. The surgical view (left) displays a dataset from a user defined camera position. The overview (right, top) displays the scene from above and the cross-sectional view (right, bottom) shows clipped images of the dataset from two predefined viewing positions. Currently no additional navigation cues are displayed.

Image-guided surgery near anatomical or functional risk structures poses a challenging task for surgeons. To this end, surgical navigation systems that visualize the spatial relation between patient anatomy (represented by 3D images) and surgical instruments have been described. The provided 3D visualizations of these navigation systems are often c...

... thus supporting users to successfully maneuver displayed instruments. The use of multiple views has been shown to help restore three-dimensionality of 2D images, thus improving anatomical interpretation and surgical performance. 2, 21 Therefore, we decided to split up our application into the following separate views, which can be seen in Fig. ...

... these risk structures as well as the cavity's boundaries. This resulted in a total of three different subtasks: precisely reaching the target structure, avoiding risk structures and keeping as far away as possible from the cavity boundaries. In order to fulfill these tasks, users could make use of our developed navigation system, displayed in Fig. 4. The figure shows the virtual cavity with target and risk structures, as ...

In laparoscopic liver resection, surgeons conventionally rely on anatomical landmarks detected through a laparoscope, preoperative volumetric images and laparoscopic ultrasound to compensate for the challenges of minimally invasive access. Image guidance using optical tracking and registration procedures is a promising tool, although often undermin...
Inter-modal image registration (IMIR) and image segmentation with abdominal Ultrasound (US) data have many important clinical applications, including image-guided surgery, automatic organ measurement, and robotic navigation. However, research is severely limited by the lack of public datasets. We propose TRUSTED (the Tridimensional Renal Ultra Soun...

Purpose
Minimally invasive alternatives are now available for many complex surgeries. These approaches are enabled by the increasing availability of intra-operative image guidance. Yet, fluoroscopic X-rays suffer from projective transformation and thus cannot provide direct views onto anatomy. Surgeons could highly benefit from additional informati...
