Tomosynthesis
Making the invisible visible
Tomosynthesis at a glance
The term ”tomosynthesis” merges ‘tomography’ and ‘synthesis’. It is a special type of imaging technology that fuses cone-beam CT reconstruction with digital image processing to produce images of specified cross-sections from a single tomography.

Provides enhanced clinical versatility
Tomosynthesis is a proven X-ray imaging technology for higher precision diagnoses. In a simple and quick workflow, and at a low exposure dose, tomosynthesis imaging technology offers high quality multi-slice images to visualize the part which is invisible for conventional plain radiography. Therefore, the technology “Making the invisible visible” is now increasingly spotlighted worldwide.
Shimadzu is a pioneer in developing and providing tomosynthesis for RF systems with the SONIALVISION series for already more than 10 years
HD Tomosynthesis
The new "High Definition Tomosynthesis" enables the reconstruction of the tomosynthesis image from original images acquired in the 1×1 high definition mode using a 6-inch field-of-view. This new mode can provide tomosynthesis images with even higher spatial resolution and will be very effective to diagnose small areas such as bones in the finger tips in detail, or to detect a very small micro-fractures.
Oblique Tomosynthesis
Provides oblique tomographic images reconstructed at any optimal angle up to ±20 degrees laterally or vertically to match the ideal diagnosis angle. This feature is helpful when examining spines, hip joints and other areas that could be difficult to observe by standard horizontal tomographic images parallel to the table-top.
Position - free tomography
Tomosynthesis by SONIALVISION allows images to be recorded at any angle required for diagnosis. This includes a variety of table angles, with the patient standing and reverse inclined position to apply gravity.
Low-dose tomosynthesis
A new “Low-dose Tomosynthesis” mode is now available to minimize the dose level even further, which makes the system ideal for pediatric use. Tomosynthesis allows multiple slices of volume data to be observed with a minimized X-ray dose, requiring a single linear tomography stroke acquisition only. By switching the field-of-view and using collimation, X-ray exposure can be reduced to prevent unnecessary radiation exposure outside the area of interest.
High-resolution images with minimal metal artifacts
The combination of high-resolution FPD and advanced imaging technology provides tomosynthesis images with excellent resolution, which are highly appreciated in the diagnoses of a micro-fracture, for example.
Another clinical key benefit of tomosynthesis images is the minimum influence by the metal artifacts that are usually seen on CT images. Therefore, tomosynthesis is nowadays spotlighted in orthopedics for the follow-up diagnosis of patients with metal implants.
