According to Toshiba, the Aquilion ONE ViSION has the ability to capture the entire heart in a single rotation which can improve cardiac diagnoses. The system offers a simplified low dose exam, and when combined with Vital Images’ CT Myocardial Analysis software, provides clinicians with images of both cardiac anatomy and function for improved diagnoses of cardiac ischaemia.
Aquilion ONE ViSION offers a gantry rotation of 0.275 seconds and 320 detector rows (640 unique slices) covering 16cm in a single rotation, and 500 microns (0.5mm) slices. The system also includes Toshiba’s third-generation iterative dose reconstruction software, AIDR 3D, which incorporates system enhancements that significantly reduce radiation dose compared with conventional scanning.
In a recent study conducted by the National Institutes of Health, analysis of data of 107 patients undergoing heart scans found that the average radiation dose was 0.93 mSv using Aquilion ONE ViSION. Image quality was also improved.
“Aquilion ONE ViSION helps diagnose cardiac disease faster and more accurately, with the ability to image the entire heart in one heartbeat,” said Satrajit Misra, senior director, CT Business Unit, Toshiba. “With its 78cm bore and fast rotation, the system can accommodate more patients, including bariatric and patients with high heart rates.”
Toshiba demonstrated the Aquilion ONE ViSION and the CT Myocardial Analysis at the American College of Cardiology (ACC.13) Annual Meeting in San Francisco, 9–11 March 2013.
