Toshiba has received FDA clearance for its Adaptive Iterative Dose Reduction 3D (AIDR 3D) technology. This is Toshiba’s third generation iterative dose reconstruction software that uses an algorithm designed to work in both the raw data and image data space, reducing noise while attempting to maintain image quality.
AIDR promises to reduce image noise and improve spatial resolution while lowering radiation exposure. AIDR 3D processing uses a scanner model and a statistical noise model considering both photon and electronic noise to eliminate noise. When AIDR is enabled in the scan protocol, the calculated exposure is automatically reduced by up to 75% when compared to a scan performed with traditional filtered back projection (FBP) reconstruction.
Reconstruction speed for AIDR 3D is comparable to that of the filtered-back projection method, important for trauma and emergency departments. AIDR 3D will be available as a software upgrade to all existing Aquilion ONE, Aquilion Premium and Aquilion PRIME CT scanners.
