BT camiasında uzun süredir tartışılan yinelemeli rekontrüksiyon, görüntü kalitesini koruyarak önemli ölçüde doz alımı elde ettiği için umut verici bir yöntemdir. Siemens Healthineers olarak, ilk ham veri tabanlı yinelemeli rekonstrüksiyon özellikli SAFIRE'i piyasaya sürerek bir kez daha düşük dozlu görüntülemede standardı belirlemiş olduk.
As 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.
