AIDR 3D
Personalized Dose Management
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.
Adaptive and Integrated Dose Management
In order to achieve the highest quality images, with reduced dose levels, the Aquilion ONE Family implements an array of adaptive and integrated dose reduction strategies. These strategies are implemented at every stage in the scanning process from patient registration through data acquisition, raw data and image reconstruction.
Patient Registration
- The system prompts the user to select the appropriate protocol based on patient age, weight and exam type
- Dose is displayed on the console prior to scanning for operator confirmation and validation
- Aquilion ONE includes the National Electrical Manufacturers Association (NEMA) XR-25 Dose Check requiring dose notification and alert features
Acquisition
- Integrated XYZ mA modulation is scanogram-based to automatically reduce patient dose
- Active Collimation limits helical over-ranging, reducing dose delivered to the patient on all helical scans
- Variable Helical Pitch (vHP) changes the helical pitch automatically from an ECG gated to a non-ECG gated exam, saving dose, IV contrast and time
Raw Data and Reconstruction
- Adaptive Iterative Dose Reduction (AIDR) adaptively targets image noise, this iterative process can be used to lower patient dose while maintaining spatial resolution and image texture
- Quantum Denoising Software (QDS) reduces image noise to optimize image quality while lowering patient dose
- Boost 3D™ improves image quality and lowers dose by selectively reducing noise and streak artifacts from those areas where it is needed
Active Collimation
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.
