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 (the LiverSurgeryTrainer) for the training of computer-assisted planning of oncologic interventions at the liver and liver living donor.

Within this first evaluation we would like to acquire your opinion towards the computer-assisted planning in general and our training system, its workflow, its operability and learnability. We assume that the test of the LiverSurgeryTrainer will take approx. 20min. Afterwards, please answer the questionnaire. That can be carried out within only a few minutes.

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

It would give us great pleasure if you participate in the evaluation and if we receive your feedback in form of a filled-in online questionnaire or a hand-written questionnaire within the next four weeks. Please note down, if something attracts your attention so that we can make changes. Finally, we will also inform you about the evaluation results.

Many thanks for your efforts.
