AIDR 3D has been developed as the next step in the evolution of noise reduction technology.
AIDR 3D, Adaptive Iterative Dose Reduction, is designed to lower radiation dose and maximize image quality all with accelerated workflow.
Integrated into SUREExposure3D settings, this iterative algorithm removes noise in the raw and image data space, by analyzing and processing the data repeatedly.
Adaptive Iterative Dose Reduction 3D (AIDR 3D) is the latest generation of Canon Medical Systems' dose reduction technology that is fully integrated into the imaging chain, and optimized for busy clinical environments.

"The balance of image quality and radiation dose is the fundamental challenge for physicians in performing routine clinical examinations while adhering to the ALARA principle. With the integration of AIDR 3D* into SUREExposure controls, the radiation exposure is automatically reduced before the scan for the diagnostic task at hand, no matter what the size or shape of the patient."
In Helical scanning, exposure is needed before the start and after the end of the planned scan range in order to reconstruct images at these positions. This over-ranging requires at least one extra rotation, although only a small portion of this data is utilized. Active collimation synchronizes the width of the X-ray beam at the ends of the scan range to the clinically useful area needed for image reconstruction. By eliminating exposure that is not used for diagnosis, patient dose can be reduced.Active Collimation Demo
