Foundation for complete ablation of a target tumor in patients using the Haifu System

3-D Conformal Treatment

The Haifu System uses real-time ultrasound imaging to target and monitor the treatment procedure. A planning session is performed to identify the target tumour volume, which is subsequently divided into parallel slices. The entire volume of the target tumour can be treated slice by slice, based on the position and depth of the target. This whole procedure is called '3-D conformal treatment'.
