HyperSense

HyperSense may not be for sale in all markets due to approval or clearance by in-country regulatory agencies.

Use HyperSense with ARC to acquire higher spatial resolution or faster imaging in multiple body regions and exam types including MRCP and TOF. HyperSense is compatible with Cube to acquire PD, T1, T2, FLAIR, DIR, contrast-weighted images. It is also compatible with most ARC-supported 3D gradient echo pulse sequences and applications. HyperSense uses a unique acceleration technique and pseudo-random k-space data sampling followed by an iterative reconstruction technique to reduce scan time.

When the HyperSense Imaging Option is selected, a factor must be selected from the Acceleration tab, HyperSense menu. The larger the value, the shorter the scan time.

Considerations

Consider this information when selecting HyperSense.

    • SNR reduction could result in a grainy appearance and possibly structured or textured-like noise patterns in low-signal bearing regions.
      • Blurring, ringing artifacts, and resolution loss could result from inadequate filling of the peripheral zones of k-space.
  • HyperSense causes a slight recon lag, in particular with coils that have a larger number of coil channels. It may be more apparent in older recon engines.
  • ASSET and HyperSense are not compatible.
  • ARC must be selected with HyperSense.
  • HyperSense does not depend on coil geometry, therefore it is compatible with any ARC compatible coil.
  • To acquire an MRCP-weighted image contrast, from the Imaging Options screen, select:
    • MRCP
    • ARC
    • HyperSense
  • HS is the Image annotation string that appears on the image and HyperSense is the abbreviation that appears on the scan control panel.
  • X (HS), where X is the value chosen from the HyperSense menu on the scan Acceleration tab. It is added after the ARC acceleration factors on the series text page.

  • When HyperSense is combined with larger Phase and Frequency scan parameter values (greater than 256) and the coil has 32 or more channels, there is a slight delay between the end of the acquisition and the start of reconstruction.
  • Susceptibility artifact may increase when HyperSense is used with BRAVO imaging.
