Quantitative evaluation for craniotomy-induced brain shift. 95th, 75th, 50th and 25th percentile (millimetres) of HD between the predicted and actual ventricle surfaces. The 95% HD was utilised as the measure of registration error. The results are compared to finite element and MTLED results from our previous studies [8, 26]
