TOSHIBA’S DOSE REDUCTION TECHNOLOGIES
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.
OUR COMMITMENT TO DOSE REDUCTION
TOSHIBA’S CT SYSTEMS – DESIGNED FOR LOW-DOSE EXAMS
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.
Aquilion RXL employs the latest dose reduction technologies such as SUREExposure 3D Adaptive, and AIDR 3D in the standard configuration.
CLINICAL EXCELLENCE WITH MINIMAL DOSE
COMPREHENSIVE LOW-DOSE EXAMINATION
Aquilion RXL 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 PUREViSION Detector technology, Aquilion RXL provides consistent image quality with an industry-leading low-contrast resolution of 2 mm at 0.3%.
Aquilion RXL is delivered with an extensive range of clinically proven scan protocols that are ready to use “out-of-the-box”.
After patient registration, the system automatically loads the correct selection of adult or child protocols based on the patient’s age. In addition, protocols are anatomically grouped with an intuitive graphical interface to ensure easy and correct protocol selection.
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
SUREExposure 3D Adaptive can achieve a dose reduction of up to 40%, depending on the individual patient and the anatomical region to be scanned.
By using AIDR 3D in combination, the dose is automatically reduced further by up to 75% before the scan. In this manner, dose reduction can be integrated into every scan protocol.
In accordance with IHE recommendations, the Radiation Exposure Monitoring Profile function is provided in the software. This function automatically records all scanning data, enabling accurate tracking of the dose for a particular study.
HIGH DEFINITION 32 SLICES IN A SINGLE ROTATION
Aquilion RXL presents the latest state of technological innovation in multislice CT technology. With the new coneXact algorithm the Aquilion RXL is able to generate 32 unique slices per rotation with more detail than ever before. No additional exposure is necessary as this breakthrough technology is entirely reconstruction-based.
Double-slice reconstruction technology provides full fidelity images with superior resolution. Details of the most intricate structures are sharply depicted in any imaging plane.
The advanced coneXact reconstruction technology originally developed for Aquilion ONE has been reengineered for Aquilion RXL to provide the same high-quality image reconstruction.
Canon’s unique double-slice solution both increases image resolution and reduces cone beam artefacts with absolutely no exposure dose penalty.
