a During MRgFUS treatment, the patient’s head is immobilized in the transducer and circulating water bath. b The water bath signal varies significantly during a single focused ultrasound (FUS) sonication (arrow indicates sonication target). c In the proposed method, undersampled dynamic data are reconstructed using the k-space hybrid method in the brain and a POCS reconstruction in the bath. d Reconstructed temperature changes and maximum temperature errors in the brain with 2x undersampling. Temperature change averaged over the hot spot center is plotted at the bottom for each reconstruction. Circles on the x-axis indicate dynamics for which temperature maps are displayed above
