In breast tomosynthesis, the X-ray tube moves through an arc while acquiring a series of low-dose X-ray images.

The images taken from different angles are reconstructed into a range of Tomosynthesis slices where the structure of interest is always in focus.

The reconstructed tomographic images make it easier to identify lesions which might be difficult to visualize in routine mammography because of the presence of overlapping breast structures.

The Tomosynthesis function on AMULET Innovality is suitable for a wide range of uses, offering two modes to cater for various clinical scenarios. Standard (ST) mode combines rapid exposure timing and efficient workflow with a low X-ray dose while High Resolution (HR) mode makes it possible to produce images with an even higher level of detail, allowing the region of interest to be brought into clearer focus.

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)

The tomosynthesis iterative super-resolution reconstruction (ISR) method is applied to optimize image quality, achieving significant X-ray dosage reduction.

Offers significantly lower doses than the conventional method

With combination of 2D and Tomosynthesis Dose of 2 or less mGy is available^*2

*1 Equivalent to an image of 40 mm PMMA compared with previous images (Breast thickness of 45 mm, 50% mammary gland, 50% fat)

*2 IAEA guidance level: 3 mGy, guidelines of the Japan Association of Radiological Technicians: 2 mGy

*In-house comparison

Two modes suitable for a range of clinical purposes

HR (High Resolution) mode

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.

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

ST (Standard) mode

The smaller angular range and fast image acquisition allow Tomosynthesis scans to be quickly performed with a relatively low X-ray dose.

• Acquisition angle: ±7.5°
• Pixel size: 100/150 m
