Title: Real-time tissue thermometry without magnetic resonance
Plain: Heating treatments need to know the temperature at the focus as it rises, which today requires an expensive magnetic resonance scanner.
Precise: Measure tissue temperature during focused ultrasound heating to an accuracy of 1 K with a spatial resolution of 2 mm and an update rate above 1 Hz, in fat-containing and moving tissue, using acoustic observables such as speed-of-sound shift, thermal strain, or backscatter change. An answer is a demonstrated technique meeting these figures against an independent temperature reference.
Settled by: Comparison with embedded thermometry or magnetic resonance thermometry in tissue phantoms and in vivo during heating.
