Monitoring temperature changes in the human skull is important in clinical transcranial MR-guided focused ultrasound, as it can absorb a large amount of energy during sonication and thereby produce heat. We propose to extract relative temperature information from proton density weighted zero TE imaging and additionally calibrate the T₁ signal contamination effect.
