Tomosynthesis, making the invisible visible

Tomosynthesis, making the invisible visible

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 provides multiple slice images reconstructed from its 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.

Position free 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 Minimal 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.

Reconstruction Method

Tomosynthesis was perceived as part of CT scanning, and a reconstruction method resulting from enhancement of Filtered Back Projection (FBP) was introduced.

“T-smart” is our latest and highest grade tomosynthesis technology evolved further with iterative reconstruction method.
T-smart provides even clearer Tomosynthesis images suppressing the artifacts around metal objects even further. This application will be a great help in the orthopedics especially for the patients with metal implants or fixators, as it enables you to diagnose the status of the boundary between bone and implant very exactly.

* Tomosynthesis is a premium option for SONIALVISION-series.
