AIDR 3D Reduces Radiation Dose in CT Imaging While Maintaining High Image Quality for Improved Patient Outcomes

TUSTIN, Calif., Aug. 27, 2012 – In CT imaging, healthcare providers strive to lower radiation dose while maintaining the high image quality needed for accurate diagnoses. Shands at the University of Florida, one of the first facilities to be upgraded with Toshiba America Medical Systems, Inc.’s newest and most advanced dose reduction software, AIDR 3D, found the technology greatly reduced radiation dose without decreasing image quality. Shands, which uses AIDR 3D with Toshiba’s AquilionTM ONE dynamic volume CT system, conducted dose measurements with phantoms and cadavers and evaluated image quality through a blind review process.

“Our initial use of AIDR 3D has been extremely promising, as we are achieving substantial radiation dose savings, enabling us to deliver better quality care without sacrificing patient safety,” said Dr. Manuel Arreola, director, Clinical Radiological Physics, Shands at UF.

AIDR 3D is Toshiba’s third-generation iterative dose reconstruction software that incorporates significant system enhancements by reducing radiation dose compared with conventional scanning. It is a sophisticated algorithm designed to work in both the raw data and image data spaces, reducing noise while attempting to maintain image quality. AIDR 3D is standard on all new Toshiba Aquilion ONE, Aquilion Premium and Aquilion PRIME CT systems.

“Working with Toshiba on the upgrade process was seamless. We were able to achieve the dose savings almost immediately, with minimal system downtime,” Dr. Arreola said.

“With patient safety top of mind, Toshiba has worked to help facilities implement dose reduction technologies that result in better patient care,” said Satrajit Misra, senior director, CT Business Unit. “Shands exemplifies how facilities can reduce concerns associated with CT dose by conducting safer CT exams.”
