Abstract

Transperineal laser ablation (TPLA) treatment of prostate cancer allows for a minimal invasive treatment approach. However, a predictive dosimetry model for accurate treatment planning for prostate cancer is not yet available. Therefore, we simulated TPLA treatments on porcine liver and quantitatively evaluated thermal distribution and histology slides were made. Hereby, we determined the cumulative equivalent thermal isoeffect dose at 43°C (CEM43) that predicts cell death and led to the development of a dosimetry model.
