TOSHIBA’S DOSE REDUCTION TECHNOLOGIES
AIDR 3D (Adaptive Iterative Dose Reduction 3D)
AIDR 3D is a sophisticated algorithm that has been designed to work in both the raw data and reconstruction domains. The collective AIDR 3D process results in robust noise reduction, which is essential for achieving ultra low-dose examinations in routine clinical imaging. This iterative algorithm is superior to non-iterative approaches in removing background noise while preserving diagnostic information.
INTEGRATED, ROBUST DOSE MANAGEMENT
Dose reduction is considered in every step of the system design, because Canon engineers recognize that all the small dose savings add up. For example, the gantry is designed with the X-ray tube located further from the patient, reducing the skin entrance dose. Astelion employs the latest dose reduction technologies such as SUREExposure 3D Adaptive and AIDR 3D in the standard configuration.
COMPREHENSIVE LOW-DOSE EXAMINATION
Astelion dose reduction and reporting technologies are integrated into every step of each scan performed, ensuring the highest possible level of patient safety.
Using Canon’s exclusive Quantum Detector technology, Astelion provides consistent image quality with an industry-leading low-contrast resolution of 2 mm at 0.3.
After patient registration Astelion selects the correct adult or child protocols automatically.
NAVI MODE OPERATION
Astelion’s Navi Mode is perfectly suited for fast patient throughput. Regardless of whether you are an expert or a novice, this unique function lets you take advantage of the system’s high performance features quickly and with ease.
The Dose Check software helps ensure that the user-defined radiation dose limits cannot be exceeded by incorrect operation of the system.
AIDR 3D can be applied to all acquisition modes in routine clinical use and is able to remove up to 50% of image noise, resulting in dose reductions of up to 75%.
SUREEXPOSURE 3D ADAPTIVE
The integration of dose reduction technologies is essential for optimal dose management. AIDR 3D has therefore been seamlessly integrated with SUREExposure™ 3D, Canon’s automatic tube current modulation software. SUREExposure 3D modulates the exposure for each patient based on a preset target level of image quality. When combined with AIDR 3D, X-ray exposure is automatically reduced before the scan, while maintaining the preprogrammed image quality adjusted based on the expected level of noise reduction. This combination provides a unique solution for robust dose management.
