Dose Reduction for Every Patient and Every Procedure
The Aquilion ONE Family of CT systems feature advanced dose reduction and image processing software. Developed based on Toshiba's long-standing commitment to improving patient safety, these features ensure delivery of the best possible image quality at the lowest possible dose. These software enhancements reinforce Toshiba's guiding principle of ALARA for every patient.
Adaptive and Integrated Dose Management
In order to achieve the highest quality images at the lowest possible dose, 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.
- 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
- 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
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.
Personalized Dose Management
AIDR 3D has been developed as the next step in the evolution of noise reduction technology.
AIDR 3D is the latest generation of Toshiba iterative reconstruction technology that is fully integrated into the imaging chain, and optimized for busy clinical environments.
Integrated into SUREExposure3D settings, this iterative
algorithm removes noise in the raw and image data space,
by analyzing and the processing the data repeatedly.
