For the first time, raw data (or sinogram data) are actually being utilized in the iterative image improvement process. With this, SAFIRE can achieve significant radiation dose reduction1. Or instead improve image quality (contrast, sharpness and noise), even surpassing the already impressive image quality realized with IRIS
Features & Benefits
• Up to 60% dose reduction1
• Superior image quality
• Fast and customizable workflow with >20 images per second
1As determined from SOMATOM Definition Flash data, SAFIRE enables up to 60% dose reduction.
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. The following test method was used to determine a 54 to 60% dose reduction when using the SAFIRE reconstruction software. Noise, CT numbers, homogeneity, low-contrast resolution and high contrast resolution were assessed in a Gammex 438 phantom. Low dose data reconstructed with SAFIRE showed the same image quality compared to full dose data based on this test. Data on file.
