CT Radiation Dose

Toshiba is committed to making CT imaging as fast, accurate and safe as reasonable for patients. Toshiba develops innovative technologies to assist physicians and technologists in reducing radiation dose and making exams more comfortable while allowing physicians to achieve their medical imaging objectives. Toshiba focuses on minimizing CT radiation through advanced CT technology and radiation reduction software:

• Toshiba supports the “as-low-as-reasonably-achievable” (ALARA) principle, which balances the clinical benefit of an imaging procedure with the potential risk of radiation exposure, the state of technology and all relevant factors.
• Toshiba’s CT systems include Quantum Denoising Software(QDS) and Boost 3D that work to minimize the radiation dose needed for CT procedures.
• Toshiba’s Aquilion^TM ONE is the only CT system with the ability to scan an entire organ, like a heart or brain, in a single X-ray rotation, meaning fewer rotations and less radiation.
  • For example, a recent study by Columbia University Medical Center published in Radiology (March 2010) reported that with the Aquilion ONE it is possible to achieve 91 percent less radiation during a heart scan called coronary angiography than with the older technology.
• Toshiba’s ^SURETechnologies™ like ^SUREExposure™ Pediatric software, which automatically takes inputs on the size and age of each patient and tailors radiation dose to achieve the best and safest image quality for each exam, is available on all Toshiba CT systems.
• Adaptive Iterative Dose Reduction software, available on the Aquilion ONE and Premium, intuitively improves the image by removing noise until the optimal image is produced, allowing scans to be performed with less radiation.

For facilities conducting exams like Cardiac CTA, Toshiba offers additional dose reduction software packages, including Variable Helical Pitch and ^SURECardio^TM Prospective, that all assist clinicians in offering the safest exams to patients
