The statement "It can map the spread of the tumour in the body" is not correct. CyberKnife is a robotic image-guided system that delivers an extremely precise dose of radiation with the capability of achieving sub-millimetre accuracy. However, it is not used to map the spread of the tumour in the body. Instead, other imaging techniques such as MRI, CT scan, or PET scan are used for the same.
