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.
