Western Australia has secured the nation's first CyberKnife, a highly advanced tool for fighting cancer.
The CyberKnife precisely targets tumours with radiation doses, reducing the impact on surrounding tissue.
It is hoped the latest model of the CyberKnife, one of only four in the world, will be used by up to 450 patients a year.
Treatments could begin in a matter of months.
State Health Minister Kim Hames says the tool will allow focused radiotherapy.
"It's not only much more concentrated on the location where it can guide that radiotherapy, [but] people might have much less treatments than they otherwise would," he said.
The CyberKnife will be in the state cancer centre which has just been opened at Sir Charles Gairdner Hospital.
Radiation oncologist Dr Colin Tang says the technology is revolutionary.
"Instead of the traditional big unit that's mounted to the floor that doesn't quite have the same degree of motion, these are miniaturised radiotherapy units mounted on the industrial robots," he said.
"Because of this they can go around a patient on a couch and treat virtually any site of the body.
"This service is available to all West Australians for no out-of-pocket expense."
The CyberKnife zeroes in on a tumour to the extent that it even follows the body movements of the patient.
But Dr Tang warns that it will not be appropriate for all patients.
"CyberKnife is one of the many forms of radiotherapy options and it is not suitable for all patients," he said.
"Where it might have advantage, for example, is in cases such as a tumour very close to a critical structure in the brain and so the CyberKnife is able to sculpt the radiation dose around the tumour and therefore you don't have this issue with blindness and other side effects you have to deal with down the track."
