We present here a new laser device allowing us to induce local temperature increase in several directions around the inserted probe to create conformational thermal ablation. The device incorporates 6 independent emitters illuminating several angles radially to the probe. We illustrate the capabilities of the device to create various heating shapes that can be visualized by real-time 2D multi-slice MR-thermometry.
