HIGH-END CT SYSTEM FOR ALL YOUR CLINICAL NEEDS, TODAY AND IN THE FUTURE Aquilion PRIME incorporates cutting-edge technologies designed to meet your current and future clinical needs. With technologies initially developed for Aquilion ONE high quality imaging at lowest dose is assured while latest clinical applications can be explored.
INTEGRATED DOSE REDUCTION Minimization of the radiation dose is a high priority for all medical imaging practitioners. The dose has to be adjusted appropriately according to the size and shape of each patient. Automatic exposure control systems have proven to be useful in doing this while maintaining diagnostic image quality. Toshiba’s SUREExposure 3D Adaptive exposure control system is fully integrated into the imaging chain and can therefore calculate the minimum radiation exposure required for each examination of each patient. With the inclusion of AIDR 3D (Adaptive Iterative Dose Reduction 3D) in the scan protocol, the exposure dose is automatically reduced by up to 75% relative to a scan reconstructed with filtered back projection. AIDR 3D is the latest evolution of iterative reconstruction technology and has been fully integrated into the imaging chain to ensure automatic dose reduction for all your CT examinations. For a dose reduction technology to be truly useful in clinical practice, it must be fast enough to fit into busy workflow schedules. AIDR 3D reconstruction has therefore been systematically optimized to guarantee maximum patient throughput. As a result, advanced iterative reconstruction with AIDR 3D can be used for every patient and every scan.
ULTRA LOW DOSE – TECHNOLOGY DESIGNED TO MINIMIZE DOSE Aquilion PRIME incorporates a variety of advanced technologies into a new-generation platform to ensure high quality images while minimizing the exposure dose.
ACTIVE COLLIMATOR The active collimator eliminates X-rays that are not used for image reconstruction in helical scanning. The collimator operates automatically at the start and end of scan range limiting the extent of the X-ray beam, permitting further dose reduction. With active collimation the exposure can be reduced by up to 20%.
CARDIO PROSPECTIVE – OVERCOME THE UNEXPECTED. Aquilion PRIME performs coronary angiography using a prospectively triggered helical technique. This ensures uniformity in the Z-axis compared to step-and-shoot techniques. SURECardio Prospective includes Toshiba’s proprietary arrhythmia rejection software which recognizes irregular heart rhythm and controls scan exposure accordingly to ensure a diagnostic study every time, and so minimize repeat examinations.
SURE EXPOSURE 3D ADAPTIVE Exposure 3D is a function that continuously modulates the exposure dose in the X, Y, and Z directions according to the patient’s body shape. Using dose modulation the exposure can be reduced by up to 40%.
VARIABLE HELICAL PITCH Variable Helical Pitch (vHP) allows definition of an exam that automatically changes the helical pitch at a user-defined location during acquisition without stopping the table motion. For example, in a CTA aorta examination, ECG-gated scanning with a slow pitch is performed for the thoracic, seamlessly switching to non-gated scanning with a faster pitch for the abdominal aorta. vHP provides an optimized workflow and short scan times when performing combined studies while significantly reducing contrast and radiation dose.
CONEXACT WITH DOUBLE SLICE TECHNOLOGY Developed for Aquilion ONE dynamic volume CT, new proprietary algorithms using the coneXact technology are available for Aquilion PRIME. Taking full advantage of the coneXact technology, acquired volume data can be reconstructed in double density, resulting in a more true-to-original reconstruction in MPR and 3D rendered images.
SHUTTLE HELICAL Toshiba’s Shuttle Helical features a unique combination of helical and volume acquisition techniques. This unique combination eliminates the need for over-ranging associated with conventional helical shuttle techniques. This results in faster cycle times and reduced patient dose.
