Advocate Lutheran General Hospital in the US state of Illinois has opened a new $6m cancer treatment facility.
The new facility, named Illinois CyberKnife, was developed in collaboration with Advocate Lutheran General Hospital, Advocate Lutheran General Children's Hospital, Radiation Oncology Consultants and US Radiosurgery.
CyberKnife uses a non-invasive method called stereotactic radiosurgery to treat tumours.
Its robotic arm aims a radiation beam directly at the tumour site, reducing damage to surrounding healthy tissues.
The new procedure involves no cutting and no anaesthesia, and the treatment can be completed in between one and five visits.
