Overview

More Clarity. More Confidence. Less Dose.1

GE’s SenoClaire* breast tomosynthesis is a three-dimensional imaging technology that uses a low-dose short X-ray sweep around the compressed breast with only nine exposures. This imaging technique is designed to separate the tissues and to reduce the overlapping of structures, which represents a limiting factor in standard 2D mammography.

Benefits

See more clearly

The SenoClaire detector delivers high DQE at low dose for visualizing microcalcifications without binning, a process that regroups pixels for faster readout speeds and improved signal-to-noise ratios, but with reduced image quality.

  • Step-and-shoot tube motion preserves microcalcification sharpness and avoids image blur, since the tube makes a complete stop for each of the nine exposures.
  • An anti-scatter solution designed for tomosynthesis, the SenoClaire grid in 3D reduces scattered radiation while preserving dose and performance. 
  • SenoClaire uses ASiRDBT, a calcification artifact correction iterative reconstruction algorithm that delivers off-plane images much improved in terms of both in-plane and out-of-plane artifacts versus the traditional Filtered Back Projection (FBP) algorithm.

Screen more effectively 
Due to its low dose and non-inferior clinical accuracy2, SenoClaire has the potential to replace digital mammography exams in screening to detect breast cancer.



Care with confidence
Because GE builds the Senographe with upgradability in mind, you can easily expand the system as your needs and capabilities grow. SenoClaire 3D breast tomosynthesis, stereotaxy, or SenoBright contrast enhanced spectral mammography are fully compatible with any Senographe Essential and Senographe Care. It’s an excellent balance of precision and performance, so you can be confident in your investment.

Connect with compatibility
SenoClaire images are compatible with major PACS providers (with local variability), allowing integration into your environment and helping you make optimal use of your investment. With the IDI MammoWorkstation, radiologists can smoothly navigate through the DBT dataset using dedicated 2D/3D hanging protocols and specific ergonomic features:

  • Straightforward visual identification of all series of tomosynthesis planes and slabs

  • Dedicated tools to review tomosynthesis data sets: cine loop, bookmarks, breast localizer, breast height ruler

  • V-Preview 3, a 2D image generated from the raw DBT projection data that helps the user get an overview of the entire stack, before examining the planes in the corresponding DBT set.



Low Dose1

It’s a requirement of dose performance that patient X-ray dose be kept as low as reasonably acceptable. The dose of a SenoClaire 3D view is equivalent to that of a 2D standard acquisition of the same view.

  • SenoClaire uses ASiRDBT, a calcification artifact correction iterative reconstruction algorithm that delivers off-plane images much improved in terms of both in-plane and out-of-plane artifacts versus the traditional Filtered Back Projection (FBP) algorithm. 
  • SenoClaire’s 3D MLO sequence requires only nine exposures with an even distribution of the dose. 
  • The SenoClaire grid in 3D reduces scattered radiation while preserving dose and performance. 
  • The dual-track X-ray tube (Mo/Rh) delivers optimized X-ray spectra to penetrate the breast based on breast density and compressed breast thickness. Automatic Optimization of Parameters (AOP) helps you identify the densest breast regions and automatically selects the appropriate anode, filter, kV and mAs to ensure repeatable image quality at optimized radiation dose.


Why upgrade?

 

Because GE builds the Senographe with upgradability in
mind, you can easily expand the system as your needs and
capabilities grow. SenoClaire 3D breast tomosynthesis,
stereotaxy, or SenoBright contrast enhanced spectral
mammography are fully compatible with any Senographe
Essential. It’s an excellent balance of precision and
performance, so you can be confident in your investment.







Upgradeable
Your Senographe Essential is built with upgradability in mind. SenoClaire is compatible with your Senographe Essential gantry allowing an upgrade at only a fraction of the cost of a new system.

Low Dose
The only FDA approved digital breast tomosynthesis that delivers the same low dose as a 2D FFDM exam.

Image Quality
The SenoClaire detector delivers high DQE at low dose for visualizing micro-calcifications without pixel binning. Non-binning results in no loss of spatial resolution, allowing small objects such as micro-calcifications to be well characterized in both 2D and DBT images.
