AngioVis Toolbox

PERIPHERAL CTA POSTPROCESSING AT ECR 2007 IMAGINE

Visualization of lower-extremity CT angiography (peripheral CTA) datasets can be very time-consuming. As part of the ECR 2007 IMAGINE exhibit, the AngioVis research group is offering to process your peripheral CTA datasets.

All ECR participants were invited to bring their own peripheral CTA datasets to Vienna, where current clinical AngioVis users from Vienna, AT and Stanford, US demonstrated the AngioVis-ToolBox on a variety of cases with peripheral arterial occlusive disease.   

The following institutions submitted cases (THANK YOU!)

  • Dept. of Radiology, University of Rome La Sapienza, Rome, Italy (P Sedati, A Napoli, C Catalano)

  • Dept. of Radiology, Mayo Clinic, Rochester, MN (C McCollough, EE Williamson)

  • Cardiovascular Section, Riverview Hospital, IN (R Hallett)

  • Dept. of Diagnostic Radiology,Tohoku University, Sendai, Japan (H Ota)

  • Dept. of Radiology, Leiden University Medical Center, The Netherlands (A van der Molen)

  • Dept. of Radiology, Universität Lübeck, Germany (T Leibecke, A Lubienski)

  • Dept. of Radiology, Medizinische Universität Graz, Austria (R Portugaller)

  • Dept. of Radiology, University of Wisconsin, WI (D Foley)

  • Dept. of Radiology II, Medizinische Universität Innsbruck, Austria (G Feuchtner)

Dedicated technologists from Vienna, AT and the Stanford 3D Laboratory processed the peripheral CT angiograms on site using new Software (AngioVis-ToolBox) which has been developed as an interdisciplinary research effort to improve clinical visualization of lower extremity CT angiograms in patients with peripheral arterial occlusive disease.

The resulting high-resolution images were printed with a high-resolution Codonics Horizon (R) Multi-media Dry Imager, and/or burned to a DICOM CD on a Codonics Virtua Medical Disc Publisher, which can be viewed with any DICOM-viewer, and even sent to PACS.

 

WHAT KIND OF POSTPROCESSING DOES ANGIOVIS-TOOLBOX PROVIDE?

 At the AngioVis booth in the ECR IMAGINE exhibit area, dedicated technologists from both clinical sites (Vienna, AT, and Stanford, US) will process your datasets. We will semi-automatically extract the arterial tree centerlines and generate a set of single- and multipath CPRs for you.

The AngioVis-ToolBox provides a standardized set of images, which can be viewed on any PACS (or DICOM) viewing workstation. The following sets (DICOM-series) of images are generated over 180° viewing-angles, respectively: 21 MIPs, 42 multi-path-CPRs and 6x11 single-path-CPRs. All images preserve the original resolution and grayscale information and can be viewed and 'rotated' by radiologists and vascular surgeons on any PACS viewing-station. Several clinical example cases can be seen here.

The clinically most useful images are often the so-called multi-path CPRs, which allow longitudinal cross-sectional viewing of all major conducting arteries in a single ('rotatable') view. For a more detailed description of single- and multi-path CPRs, please see our publication section on this website.
