Precision Positioning Robot
What does it do? First, the doctor identifies and marks the location of the cancer lesion within the breast in 3 dimensions using MRI images. Once the Judith robot knows where the cancer is, the Precision Positioning Robot does the rest: it determines an insertion path and depth, and smoothly and precisely inserts the needle so the needle tip is right in the center of the cancer. The first needle delivers anesthetic, and because the robot is so precise, it EXACTLY follows the same path with additional interventional tools. The patient can hardly feel a thing. Judith gets you there!
Since an MRI is a powerful magnet, no ferrous metal is allowed anywhere near it. Therefore, to be able to function within an MRI, Judith is constructed entirely with non-ferrous or non-conducting components. Engineering a complex and precise robot so it can be manufactured without any ferrous metal pieces is quite a feat!
