Dear Colleagues, We are glad to announce the ３rd Virtual Intracranial Stenting Challenge (VISC09). The objective of this year’s challenge is to assess the ability of engineering teams with expertise in computational haemodynamics in providing clinical partners with valuable pre-treatment information within the time constraints of an elective endovascular intervention. The VISC09 will be carried out over the month of August 2009 and will be presented during a moderated poster session in occasion of the 6th Intracranial Stenting Meeting (ICS09) to be held on Aug 5th-7th 2009 in Sendai, Japan. The teams interested in participating to the challenge will be given access to patient and stent data and will be expected to perform 3D vascular geometry reconstruction, virtual stent deployment and hemodynamic simulation, possibly using the provided flow information. The output of each team will be an independent analysis illustrating advantages and disadvantages of each candidate stent for the selected patient. The results will be provided to the VISC committee in the form of a poster, whose standard format will be soon available on the VISC website. Deadline for poster submission will be May 31, 2009. Each poster will be then displayed in the occasion of the ICS09 in Sendai and peer-reviewed by all attendances including expert clinicians and engineering researchers. During a special session, the VISC committee and you will present the approach and the major findings of each poster and will select a maximum of 2 questions/suggestions provided by the clinicians to interview the attending teams. A separate roundtable discussion between attending teams and interested clinicians will be also organized. Reviews will be made available to the teams who won’t be able to attend to the conference, although teams are strongly encouraged to participate to the conference. Please take a moment to download the guidelines, where you will find information on how to register to the challenge and obtain access rights to the patient and stent data. We anticipate that the interaction between teams to jointly achieve the goals of the challenge is encouraged. Please feel free to contact Makoto Ohta (ohta@biofluid.ifs.tohoku.ac.jp) or Toshio Nakayama (nakayama@biofluid.ifs.tohoku.ac.jp) should you have any comment or doubt.
Yours Sincerely,
The VISC committee Makoto Ohta, Institute of fluid Science, Tohoku University
