0001 Disclosed in the present invention are an automatic determination method and system for ultrasound ablation balloon apposition. The method comprises the following steps: setting related working parameters; after a balloon moves to a target ablation area, injecting normal saline; measuring a pressure in the balloon and an impedance outside the balloon, and feeding back same to a control system; and determining whether the balloon fits with the wall of a blood vessel well. According to the technical solution of the present invention, a pressure in a balloon and an impedance outside the balloon are measured at the same time and compared with set values and set change ranges, such that accurate and automatic determination of an ultrasound ablation balloon fitting with the wall of a blood vessel is achieved, and it is ensured that ablation operation is started after the ultrasound ablation balloon fits with the wall well, thereby greatly improving the ultrasonic transmission efficiency and the ablation operation effect.
