Accurate temperature assessment during liver ablation requires a dedicated method for motion correction. We present the first results of a prospective motion correction method for thermometry during microwave ablation using an optical Moiré Phase Tracking system. Ex-vivo studies showed a mean temperature deviation of ΔT = 0.4 °C compared to ΔT = 34.6°C without motion correction. The method can easily be integrated into the work flow if optical tracking is applied for needle placement.
