Shimadzu realized the world’s first practical use of Tomosynthesis on RF-table systems, SONIALVISION series, with the latest Flat Panel Detector and advanced Digital Imaging Technology.

This state-of-the-art imaging technology offers high quality multi-slice images to visualize the part which was invisible by the conventional plain radiography, in a simple and quick workflow, and at low exposure dose. Therefore, Tomosynthesis is now spotlighted more and more in the world.

What is “Tomosynthesis” ?

”Tomosynthesis” is a coined term from ‘Tomography’ and ‘Synthesis’.

It is a new type of imaging technology that fuses cone-beam CT reconstruction with digital image processing to produce images specified cross sections from a single tomography scan. It used the reconstruction method resulting from enhancement of Filtered Back Projection (FBP), and provides multiple slice images reconstructed from the volume data.

What will be realized by Tomosynthesis ?

Reduce examination time and X-ray dose 

Since the images of a specific cross section can be reconstructed from a single low dose tomography scan motion only, this technique requires less time and less x-ray dose to obtain multiple slice images than conventional linear tomography. 

The short examination time would be very helpful to the stressed or immobile patients.


Free position tomography

Tomosynthesis by SONIALVISION allows recording of images at any angle required for diagnosis, including a variety of table angles or with the patient standing and reverse inclined position to apply gravity, which is not possible by CT scanners. It helps expand the examination range and remedy possibility.

High resolution images with less metal artifacts

The combination of high resolution FPD and our advanced imaging technology realizes excellent resolution Tomosynthesis images which are highly appreciated in the diagnoses of a micro-fracture etc. 
Another key clinical benefit is that Tomosynthesis images has minimal influence from the metal artifacts that are usually seen on CT images. Therefore, Tomosynthesis is nowadays spotlighted in the orthopedics for the follow-up diagnoses to the patient with metal implants.

T-smart PRO assisted by AI Tomosynthesis-Shimadzu Metal Artifact Reduction Technology PRO

“T-smart PRO” is our latest and highest grade Tomosynthesis technology, providing tomographic images with less metal artifacts, in an efficient workflow utilizing deep learning technology. 
Shimadzu metal artifact reduction technology with AI (Artificial Intelligence) image processing enables to focus on patient care by providing easy-to-interpret Tomosynthesis images with more efficient workflow.

Easy-to-interpret Tomosynthesis images minimizing metal artifacts

T-smart PRO provides enhanced Tomosynthesis images by further suppressing artifacts around metal objects using an iterative reconstruction method. This application greatly helps orthopedics especially for patients with metal implants or fixators, as it enables diagnoses the boundary between bone and implant very exactly.

Efficient workflow assisted by Shimadzu AI technology

The entire workflow is so simple that anyone can obtain Tomosynthesis images with ease and efficient workflow. Shimadzu AI image processing technology automatically adjusts reconstruction parameters to simplify and optimize its workflows, so there is no need extensive skill and time.

* The AI (Artificial Intelligence) technology used in T-smart PRO is a "trained model" that was trained at some point and performed accuracy evaluation.
It doesn't continue learning after installation.

The boundary between the artificial joint and bone is clearly depicted,
and it is useful for evaluation of implant-bone fixation.

Surgery repaired ulnar fracture
The fractures around fixing plate can be clearly observed by suppressing the metal artifacts.

Precise diagnosis of heel micro-fractures
Multiple slices of Tomosynthesis can show the micro-fracture in detail.

Compression fracture of the lumbar spine
Lumbar fractures that are difficult to visualize on radiographs because of overlap can be clearly observed.

Clear observation of pulmonary emphysema
A short scan time provides clear, blur-free lung images, and patients don't have to hold their breath for long periods.

* Tomosynthesis and T-smart PRO are premium options for SONIALVISION G4.
