Exceptional Image Acquisition Technologies: AuroraEDGE™ and SPIRAL Breast ImagingAuroraEDGE

The new AuroraEDGE technology radically improves image resolution and eliminates common breast MRI artifacts for crystal clear images of both breasts, axillae, chest wall and mediastinum in a single, 3-D bilateral scan.

The unique pulse sequence and image acquisition system used in AuroraEDGE technology minimizes the effect of common cardiac motion on the images. The new acquisition efficiency of AuroraEDGE is used to oversample for a larger field-of-view to

avoid aliasing.

AuroraEDGE Image Specifications:

  • 3-D Image Resolution 512x512, 250 slices

  • 0.7 mm slice thickness, no gap between slices

  • Offers isotropic true 0.7mm resolution in all 3 planes

  • Post-contrast time points obtained at 90-seconds, 4.5-minutes, 7.5-minutes, and 10.5-minutes​.


3-D Bilateral Spiral Breast Imaging

By offering Spiral breast imaging technology, Aurora became the first manufacturer to commercialize this advanced image acquisition technology for breast anatomy. Now, you no longer have to choose between higher image quality (contrast resolution) and temporal resolution – Spiral gives you both. Spiral breast imaging provides dramatically increased resolution along with a significant decrease in scan time for improved dynamics. This innovation is achieved while still maintaining all the contrast advantages proven with RODEO® technology – outstanding suppression of fat and normal ductal tissue. Spiral breast imaging significantly improves spatial and temporal resolution because it is extremely efficient in acquiring data for image reconstruction, which results in a significant boost in signal-to-noise ratio (SNR).

A spiral trajectory through reconstruction space acquires image data beginning at the center and spiraling to the periphery continuously through the readout. Much more of reconstruction space is covered, and the better acquisition efficiency leads to improved resolution. Since the center of reconstruction space accounts for most of the image contrast, the oversampling of the center of reconstruction space also results in improved image contrast.
