Abstract: Mini-invasive surgery restricts the surgeon information to two-dimensional digital representation without the corresponding physical information obtained in previous open surgery. To overcome these drawbacks, real time augmented reality interfaces including the true mechanical behaviour of organs depending on their internal microstructure need to be developed. For the case of tumour resection, we present here a finite element numerical study of the liver mechanical behaviour including the effects of its own vascularisation through numerical indentation tests in order extract the corresponding macroscopic behaviour. The obtained numerical results show excellent correlation of the corresponding force-displacement curves when compared with macroscopic experimental data available in the literature.
