Images obtained through different methods. a The positions of a mini-invasive needle and the injected gallium are determined through ultrasonic imaging. b The position of the injected gallium was determined through X-ray imaging (front and side views). c. The position of the injected gallium was determined, and the tissue was analysed before injection, after injection, and after ablation through MRI tomography (axial and coronal views). The ablation time was 10 s
