GE's ASiR technology reduces radiation dose in CT scans

9 Dec 2010

GE Healthcare showcased some of its latest CT innovations for reducing the radiation dose received by patients at the recent RSNA congress.

GE's ASiR (adaptive statistical iterative reconstruction) low dose reconstruction technology, available on the GE Discovery CT750 HD and LightSpeed VCT, can reduce dose by up to 40-50% while maintaining image quality and can be implemented as a cost-effective upgrade for existing GE LightSpeed VCT customers. The technology can be used on both helical and axial scans to reduce dose and maintain image quality for patients of all ages.

ASiR, in concert with GE’s SnapShot Pulse technology, further helps physicians to reduce dose cardiac imaging by more than 83%. ASiR is now routinely used with over 600 scanners worldwide, benefiting more than 15,000 patients per day on well over three million exams to date.

"I am astounded at how sharp the ASiR images are and how low the noise level is. This is very important, considering the significant dose savings that can be achieved with it,” noted Richard Kane MD, Director of Cardiovascular & Thoracic Radiology, Saint Francis Hospital, Evanston, IL.

GE’s Model-based Iterative Reconstruction Technology — Veo

GE is also highlighting the newest low-dose technology in the company’s CT portfolio — a model-based iterative reconstruction (MBIR) technology called Veo currently available in Europe. It is  pending approval by the US FDA and not yet available for sale in the US.

When compared to previous GE reconstruction methods, Veo’s capabilities “change the rules” of CT imaging by applying revolutionary new modeling techniques to deliver lower noise, resolution gain, improved low contrast detectability and artifact suppression.

“GE’s commitment offers tremendous promise for equipping radiologists and technologists with breakthrough technologies to reduce patient dose and improve image quality in their daily practice,” said Steve Gray, Vice President & General Manager of Computed Tomography & Advantage Workstation for GE Healthcare. “Through low-dose innovations, educational symposiums and collaborating directly with customers and the industry, we strive to help improve the overall care provided to patients.”
