Care kV, a recent addition to Siemens' dose reduction portfolio, selects the correct tube voltage depending on the patient's anatomy and the organ to be imaged, with all other parameters automatically adjusted to suit the selected kV level. Care kV optimizes the contrast-to-noise ratio of the image and enables dose savings of up to 60 percent. Siemens' SAFIRE¹[<00B9>][<00B9>] (Sinogram Affirmed Iterative Reconstruction) software solution delivers significant dose reduction in a wide clinical spectrum, providing excellent image quality and improved workflow.
1 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.
