Siemens Healthineers nuclear medicine head scan using SAFIRE.

SAFIRE
Sinogram affirmed iterative reconstruction

SAFIRE¹ is a unique CT iterative reconstruction algorithm that uniquely allows for up to 60% lower radiation dose in your CT examinations without compromising image quality.

Features & Benefits

Recognized as a strong iterative reconstruction algorithm²
Significant noise reduction² while maintaining image quality and detail visualization
Low-dose procedures may contribute to an increase in patient referrals, along with patient satisfaction
Designed for simple implementation and easy use

Reduce image noise

In this case, SAFIRE helped to significantly reduce the noise in the CT image while using a low-dose protocol. This study was performed on a Symbia Intevo Bold™ SPECT/CT with 42 mAs at 110 kV, resulting in a DLP of 116 mGy*cm.

Improve image quality

In this case, SAFIRE allows for excellent CT image quality with oral and IV contrast medium, supporting the staging of adenocarcinoma. The study was performed on a Biograph™ Horizon PET/CT with a 1 minute per bed position and CT scan parameters of 60 ref mAs at 130kV.

Acquire images at lower dose¹

With SAFIRE, excellent co-registered CT images obtained at a low dose (130kV / 61 ref mAs) allowed for the characterization and delineation of a sub-centimeter lung lesion.

Did this information help you?

In clinical practice, the use of SAFIRE may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.
