Step by step guide Focal One treatment step by step 1. Patient is lying on the right side during the treatment.2. Image illustrates position of the probe relative to the rectum. 3. Thanks to the proximity between the prostate and the rectum wall, treatment is carried out particularly optimally in the intrarectal position. 4. Probe is now inserted into the rectum up to the level of the prostate. The bladder is located above and the urethra passes through the prostate.5. Imaging transducer in the middle of the probe allows a very precise three-dimensional computer reconstruction of the area to be treated.6. All the prostate is scanned and reconstructed through the movements of the probe and the computer program. 7. On the screen, the doctor plans every step of the treatment with millimetric precision.8. Finally, the device automatically realizes the optimal number of lesions following the planning carried out by the urologist.9. An MRI can confirm the treated area.
