title: [Comparison of ablation effect of Nd:YAG laser with different power and energy based on ultrasound guidance].
abstract: To explore the optimum laser power and energy in porcine thyroid ablation in vitro with 1 064 nm Nd:YAG laser of different power and energy guided by ultrasound after comparison of size and pathology of ablation lesions. The experimental results showed that Laser ablation effect of porcine thyroid in vitro is definite, the size of ablation lesions increases as the laser power and energy increases, when the laser power and energy are 3 W and 1 800 J, the ablation lesion effect reaches ideal level.
