Özellikler ve Faydalar

Stellar ready

“Stellar ready” means that the SOMATOM® Definition AS now offers you the option to upgrade to a Stellar detector. As the first fully integrated CT detector, it measures smaller signals over a wider range and enhances image quality.

CT Stellar Detector

The new SOMATOM Definition AS Stellar ready now offers you the option to upgrade the system with a Stellar detector. The system is also designed to be able to rotate with 0.28 s and makes possible a scan speed coverage of up to 23 cm/s.

  • The Stellar detector is the first fully integrated CT detector. It enables processing of the digitized signal without any losses while reducing the electronic noise of the detector (TrueSignal technology).
  • In combination with Edge technology, the system therefore delivers a much sharper slice profile and makes possible the reconstruction of true 0.5 mm slices and offers unmatched spatial resolution in routine clinical protocols with excellent dose efficiency.
  • In addition, HiDynamics extends the dynamic range up to 102dB, which eliminates the need to modify amplification and avoids detector saturation.

Systems with the Stellar detector can therefore measure smaller signals over a wider dynamic range – which directly reduces the noise and enhances the CT image quality.

Highlights

  • Full flexibility to upgrade to a Stellar detector
  • Processing of the signal without losses
  • Reduction of electronic noise
  • Enhanced image quality
  • Dynamic range up to 102 dB
  • Scan speed of up to 23 cm/s and rotation of 0.28 s

1In 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.

2syngo.via can be used as a standalone device or together with a variety of syngo.via-based software options, which are medical devices in their own right.

3The 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.
