I work in the Tampere University Hospital as dental assistant and we have this new cone beam computed tomography system which is in clinical validation use. Soredex is the imaging system provider from Finland which has introduced a new in-office large field-of-view Cone Beam 3D CT system Scanora 3D for head and neck imaging till many hospital like ours as well. I will tell some experience in using the system in various indications here.
The Scanora 3Dx is a new member of the Scanora CBCT product family. Compared to its predecessors, the Scanora 3Dx has a larger flat panel detector, which enables a wider range of imaging fields-of-view (FOV) to be used. The same smooth workflow with clear control screen and motorized patient positioning movements’ charities this new accuracy instrument. The optional dental panoramic sensor is available as previously.
In the unit there are now eight user selectable FOVs available. All the FOVs have their typical applications. The smallest cylindrical FOV with the highest resolution size is intended for localized problems, such as detailed imaging of single tooth endodontic structures or acicular chain of the inner ear. Several medium-sized FOVs are available for imaging, for instance, both temporal bones in one volume. The voxel volume is isotropic, which ensures that measurements in any direction are accurate.
The Scanora 3Dx takes the advantage of the latest imaging technology. The 3D detector is a large amorphous Silicon flat panel for acquiring high-resolution projection images. The reconstruction method SARA produces 3D volumes out of these projection images. More accurate patient positioning is achieved with more developed laser lights and scout programs. The overall radiation dose for specific diagnostic tasks can therefore be optimized by selecting the smallest FOV for each task and adjusting the mA and resolution accordingly. CBCT in recent years has had a remarkable effect on the diagnosis of head and neck diseases as like as in the Tampere University Hospital. The advantages of CBCT over MDCT are the low radiation dosage, patient comfort, minimal patient interaction and lower expenses.

I enjoy writing informative blogs, articles and reviews. I like to think my writing as an online resource; help answer end-user questions and lead others in the direction they are looking.
