Siemens' SAFIRE Iterative Reconstruction Protocol Cleared by FDA

 

December 13, 2011

The SAFIRE – Sinogram Affirmed Iterative Reconstruction – computed tomography (CT) iterative reconstruction algorithm from Siemens allows for a robust reduction of radiation dose in CT examinations.

Additionally, the use of projection raw data during the iterative image improvement process enables a reduction of subtle image artifacts; this provides a further improvement in general image quality.

SAFIRE helps users reduce dose by up to 60 percent compared to previous filtered back projection techniques, as documented in the FDA

The extremely fast reconstruction speed of 20 images per second enables reconstruction of a typical high-resolution thorax examination of 30 cm in just 15 seconds. With this, the system can be applied routinely in clinical practice.

SAFIRE is available for Siemens Somatom Definition Flash and Somatom Definition AS CT systems; it will be available on the Definition DS in mid-2012.

The company’s current iterative reconstruction method, IRIS (Iterative Reconstruction in Image Space), will remain available for Somatom Definition dual-source systems. Additionally, due to the overwhelming response to IRIS in the Siemens CT install base, it will be available for Somatom Emotion 16 (2007) and Somatom Sensation 40, 64 and Open CT systems.

Siemens will exhibit in booths #442, 822 and 1642 at RSNA 2011.
