It's Saskatchewan's first positron emission tomography-computed tomography scanner, better known as a PET-CT scanner.
The scanner is primarily used to detect cancer, help with treatment recommendations and track prognosis.
For example, a PET-CT scan can help determine if a mass is malignant or benign and differentiate between scarring and a recurrent tumour.
Hundreds of Saskatchewan cancer patients used to have go to Edmonton or Winnipeg to get the scans.
Saskatoon Health Region says it expects to provide service to 1,200 patients from across the province this fiscal year and 1,900 patients a year after that.
