December 14, 2011 — Toshiba America Medical Systems Inc. unveiled the Adaptive Iterative Dose Reduction 3-D (AIDR 3-D), its next generation dose reduction technology, at RSNA 2011. Still pending 510(k) approval from the U.S. Food and Drug Administration (FDA), the software will be available on Toshiba’s Aquilion One, Aquilion Premium and Aquilion Prime (also pending 510(k) clearance) systems.
AIDR 3D lowers radiation dose compared to conventional scanning, aiding clinicians in accurate diagnoses and treatment planning. It is a sophisticated algorithm designed to work in both the raw data and image data space, reducing noise to maintain image quality.
“The AIDR 3D images look very similar to those reconstructed with classic filtered back projection. We have not noticed any plastic effect or loss of spatial resolution,” said Professor Alain Blum, chief of radiology, Centre Hospitalier Universitaire, Nancy, France. “AIDR 3D is a fine solution to dramatically reduce X-ray dose and improve image quality, and should be immediately adopted when installed on your Toshiba CT system.”
The new feature has also been seamlessly integrated with SUREExposure 3-D, software that can calculate the minimum radiation exposure required for every exam. It adjusts dose for each patient based on a pre-set, targeted level of image quality.
