Dear Sir or Madam,

Within the frame of the support program "SOMIT - Gentle Surgery by Innovative Technology" the Visualization Group is concerned with the development of a software for the training of computer-assisted planning of oncologic interventions at the liver and living donor liver transplantations: The LiverSurgeryTrainer.

In 2007, we evaluated the first prototype of the LiverSurgeryTrainer. The results were integrated in the further development. We adapted in particular the training steps and gave them more guidance. Now we´d like to evaluate the final version of the LiverSurgeryTrainer and hope for your participation. We assume that the test of the LiverSurgeryTrainer will take approx. 30min. We advise the case "Case #Onko1: Celle-PU" for your test. Afterwards, please answer these online questionnaire. It can be carried out within only a few minutes.

The cases contained in the LiverSurgeryTrainer are real cases, courtesy of Prof. Oldhafer (Asklepios Klinik Barmbek, previously General Hospital Celle) and Dr. Hillert (University Medical Center Hamburg-Eppendorf) and edited by the Mevis Distant Services AG.

We would be glad if you could participate in the evaluation and if we receive your feedback in form of a filled-in online questionnaire within the next four weeks. If you notify any problems, please do not hesitate to contact us.


Many thanks for your efforts.
