The current robotic surgical system cannot run on its own, it has to be maneuvered by a surgeon. While opinion is divided on the outcome, top surgeons, however, do not rule out such a possibility.
Presently, robotic equipment can take you to the abnormal area like tumor, blood clot and abscess so that tissues can be biopsied safely. The next stage will be robotic instrument that can be manipulated 360 degrees, conducting the biopsy on its own based on the program fed into the software system.
The Doctor said this could be done because the team had the benefit of all diagnostic imaging—CT scan and MRI—results being fused together into robotic computer, so the mechanical arm can avoid damage to other organ.

In 1970s, till the CT scan was made available, surgeons would explore just on history and clinical examination to see which part of brain is involved. But now we have advanced imaging system such as MRI to explore all details of the abnormality.
