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
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
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
“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.”
