Low Dose CT Scans

Hunter Radiology uses two advanced multi slice CT Scanners. These CT Scanners have various tools to help us reduce dose. The biggest innovation are the iterative reconstruction techniques, iDose4 and AIDR 3D. These allow Hunter Radiology to reduce dose, using less x-rays to get the same image quality.

Philips iDose4 and Toshiba AIDR 3D are iterative reconstruction techniques that allow Hunter Radiology to produce low dose CT Scans and still maintain excellent diagnostic images.

Hunter Radiology first introduced iDose4 when we installed our Philips Ingenuity 128 slice scanner in July 2011. We were immediately able to reduce our CT Dose by 25%. When Hunter Radiology opened a new practice on Lake Road Glendale we wanted to continue and hopefully improve our Low Dose scans. The Toshiba Aquilion Prime, with AIDR 3D was an obvious choice. Toshiba, like Philips, combine multiple dose saving techniques to reduce radiation dose.

All of these dose saving techniques are helpful, but they do not produce the lowest dose every time. To do this Hunter Radiology rely on our well trained and motivated staff to continue to push the limits of low dose scanning, while still producing the high quality images. Our CT Radiographers have looked at the differences in exposure factors between our two scanners. They have used the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) guidelines on CT dose to reduce our CT doses even further. Our CT Dose is now lower than the national guidelines.

Hunter Radiology has a commitment to our patients to use Low Dose techniques and ensure that the diagnostic quality of our medical imaging is not compromised
