Tomosynthesis

High quality images for easier diagnosis

Tomosynthesis: making it possible to observe the internal structure of the breast

S-View(synthesized 2D image)function is available

Tomosynthesis by AMULET Innovality automatically produces not only tomograms obtained at 1 mm intervals but also a two- dimensional S-View image combining multiple slice images.
With the S-View image showing the overall view added to tomograms offering the views in detail, comprehensive image reading is possible.

ISR (Iterative Super Reconstruction)

1. Reducing graininess of image in low-dose tomography

The image patterns are recognized to selectively suppress the patterns that do not exist in human body architectures as noise, to reduce distractive noises in the event of low-dose tomography.

2. Suppressing interference of human body architectures at different depths (as illustrated on the right)

In the process of reconstructing the 3D breast architecture from multiple 2D images, calcification, mass, spicula, mammary gland and other signals that emerge from different depths in the breast architecture are selected off to reproduce the breast architecture at the focus depth with greater fidelity.

3. Restoring the fine-structure

Our super-resolution technology is introduced to restore the fine-structure of calcification and other phenomena, the visibility of which is impaired by the movement of the X-ray tube, to facilitate interpretation of tomosynthesis images.

Offers significantly lower doses than the conventional method

Two modes suitable for a range of clinical purposes

HR (High Resolution) mode

Acquisition angle: ±20°
Pixel size: 100/50 m

With a larger acquisition angle the depth resolution is improved. This allows the region of interest to be defined more clearly and brought into clearer focus.
