TEMPERATURE MONITORING APPARATUS AND METHOD FOR MONITORING A TEMPERATURE WITHIN A TISSUE

摘要

A temperature monitoring apparatus (40) is disclosed for monitoring a temperature within a tissue (10), in particular during a thermal ablation process. The monitoring apparatus comprises a temperature application unit (42) configured to introduce heating power into the tissue for heating the tissue. The monitoring apparatus further comprises an ultrasound unit (44) for emitting and receiving ultrasound waves and for determining a temperature in the measurement region (22, 24) of the tissue on the basis of ultrasound shear wave detection. The monitoring apparatus further comprises a temperature estimation unit (46) including a heat transfer model (48) for estimating a temperature in a region of interest (26) within the tissue, wherein the heat transfer model is based on medical images of the tissue.
