Figure 1. The image shows the intraoperative combined use of LOCalizer™ and intraoperative ultrasound. The Pencil (labeled 1) approaches the lesion, following the indication of the distance in millimeters (A) from the Tag but the surgeon cannot recognize the margins of the lesion. Intraoperative ultrasound (labeled 2) enables identification of the perimeter of the lesion and the distance to the margin (B), improving oncological safety and enabling minimally invasive resection.
