  1. AIt is a robotic image guided system
  2. BIt delivers an extremely precise dose of radiation
  3. CIt has the capability of achieving sub-millimetre accuracy
  4. DIt can map the spread of tumour in the bodyCorrect

Explanation

The CyberKnife is a robotic radiosurgery system used for treating tumours, not for diagnosing or mapping the spread of cancer throughout the body. While options A, B, and C describe its functions as a precise, robotic radiation delivery system with sub-millimetre accuracy, option D is incorrect because mapping the spread of cancer is typically done using diagnostic imaging tools like PET scans or MRI. CyberKnife is a treatment tool, not a diagnostic mapping tool.
