Radiofrequency Ablation
Conditions
Brief summary
Ultrasonic-guided radiofrequency ablation is the most common minimally invasive treatment for liver cancer. This study will use my country's self-developed intelligent ultrasonic navigation tool (NAVIRFA® Navigation System) to assist in the puncture of the needle during ablation, to observe the operation time, Whether the needle accuracy, ablation effect and complications are different from the traditional free-hand ultrasonic guidance technology.

Inclusion criteria
1. Patients with malignant liver tumors less than three centimeters in size who are expected to suffer radiofrequency tumor ablation in the hospital. 2. At least 20 years old.
Exclusion criteria
1. Patients with abnormal coagulation function and low platelets are not suitable for ablation therapy after evaluation by the trial host. 2.
