Our modern flat-panel digital radiography achieves the practical use of Tomosynthesis. The new diagnostic imaging technology offers high image quality at low exposure dose.

What is Tomosynthesis?

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

Standing Position Tomosynthesis

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. CT imaging is reconstructed.

What is Tomosynthesis Features?

Reduce Examination Time and X-ray Dose

Since an image of a specific cross section can be reconstructed from a single tomography scan, this technique would be require less time to acquire than standard tomography. The reduced exposure time would be useful where patients may be stressed or where immobilization for longer periods would normally be employed. (one-tenth the dose of CT) Besides, repeated reconstruction is possible from exposed data.

Position free tomography

Tomosynthesis 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. It helps expand the examination range and .remedy possibility.

Fewer Metal Artifacts than CT Images

The system produces images with minimal influence from the metal artifacts that are usually seen on CT images. This would be useful in follow-up examinations after orthopedic surgery where metal implants may have been inserted.

Reconstruction Method

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

Tomosynthesis is an option for SONIALVISION safire17, digital fluoroscopy system with a direct conversion FPD.®
