The new scanner would enable clinicians to deliver uncompromised image quality for some of the most challenging situations, he said.
A computed tomography scan, known as a CT scan, used X-rays to make detailed pictures of a body's interior. It was important in the diagnosis of disease, trauma, or abnormality.
Cancellation due to breakdowns and other technical difficulties would be a thing of the past as there would now be a back-up scanner, Mr Potts said.
Another benefit to patients was reduced radiation exposure with the new scanner.
It would also improve faster cancer treatment targets as 21 per cent of all current outpatient referrals were from the oncology service.
It was faster, making it easier to examine a variety of patients.
The radiology suite upgrade cost $2 million, which included the two CT scanners and facilities, Mr Potts said.
