A distributed system for 3D anatomical structures visualization and surgical planning

摘要

The progress made in medical imaging has led to enhanced diagnostic capabilities. Nevertheless, the analysis of the complex information contained in a set of 2D CT-Scan or MRI slices is a hard task : physicians have to mentally rebuild the images to obtain a 3D view of a patient's organ. The proposed system is a secure PACS (Picture Archiving and Communication System) including a 3D visualization interface consists of a set of tools which helps the physician in his pre- and intra-operative strategy. The present system is a distributed architecture allowing secure storage and 3D visualization of anatomical structures reconstructed from CT-Scan and MRI images. Patient information and data are stored in distant databases accessible through the hospital network by using a user-friendly visualization interface. This surgical planning tool consists of : a virtual resecting tool allowing for simulation of surgical procedures, permitting insertion and manipulation of virtual laparoscopic tools, display of security margins, calculating 3D distance, and computation of organ volume. Finally, one major advantage of the visualization interface is that it works on a simple laptop, which can be temporally disconnected from the hospital network, allowing for consultation of reconstructed exams in the operating room.
