Abstract
Disclosed are a compatible system and a compatible method for synchronize working of magnetic resonance imaging and focused ultrasound thermal ablation. The compatible system for synchronize working includes a magnetic resonance device and a focused ultrasound device, further includes a signal collector and a control circuit connected to the signal collector. In an imaging process of the magnetic resonance device, the signal collector is configured to detect a radio frequency (RF) signal of the magnetic resonance device, and the control circuit is configured for recording a trigger time of the RF signal, generating an enable signal triggering the focused ultrasound device to start heating based on the trigger time of the RF signal, and controlling a heating duration of the focused ultrasound device according to an echo time.
