Asteion™ Super 4 Edition


Data acquisition

Isotropic volume acquisition

The Quantum detector leverages Toshiba's expertise in ceramic technology to capture true isotropic images with 0.5 mm slice acquision. This provides clinicians with high-quality volume data sets that:

  • Have the optimal voxel size for any region of the body
  • Share axial image quality in all imaging planes
  • Offer highly detailed MPR and 3D views of anatomy and pathology

SUREExposure

Real-time exposure control with SUREExposure™ automatically adjusts the tube current to patient anatomy to reduce dose with no loss in image quality.

  • Up to 40% dose reduction
  • Automatic tube current modulation
  • Dose optimized for each patient's anatomy

Image processing

Quantum denoising software

Quantum Denoising Software (QDS) is a powerful tool Toshiba has developed to remove noise in reconstructed images. QDS is an adaptive noise reduction algorithm that selectively smoothes out areas of uniform density while preserving the edge information within the image, thus reducing noise while increasing the signal to noise ratio and improving image quality.
QDS routinely reduces patient dose by up to 50% while maintaining both low and high contrast resolution.

Bone Removal

Toshiba's bone removal software provides the operator with an easy and accurate means of removing bone from CT angiographic images.
Extremely high-quality MIP images with bone segmentation can be obtained in just a few clicks. Toshiba provides realtime preview of bone removal on synchronized 3D and MIP images to ensure highly accurate and diagnostic 3D CT angiograms every time.


Usability

Couch and gantry design

A long 1,800 mm scanable range, wide 47 cm couch width and a large gantry aperture of 72 cm are enhanced by the following design features.

  • Auto set/Auto-home of the couch with foot switch operation to keep the operator "hands-free"
  • Lowest couch height of 31 cm
  • Gantry tilt/couch control from console
