This image depicts PelVis , an interactive application for surgical planning for the Total Mesorectal Excision (TME) procedure. During this surgical procedure, undesired side-effects occur in up to 80% of the cases due to damage to the autonomic nerves. These nerves are damaged easily, since they are not visible in pre-operative MRI or even during the surgery. In order to visualize these nerves, we built an atlas model, the Virtual Surgical Pelvis (VSP) , that reveals zones in which the autonomic nerves reside based on cryosection and immunohistochemical studies. In the PelVis application, we register this atlas to patient-specific clinical MRI data and thus are able to make patient-specific virtual models of the individual patient, and to reveal the autonomic nerve zones pre-operatively, as displayed here in yellow. We highlight the distance of the mesorectal wall to these nerve zones using a colormap (red to white) combined with isolines. Furthermore, other surgically relevant anatomy is shown for spatial context, without occluding the view on the mesorectum, and the linked atlas-enriched MRI data can be explored interactively .
