Cone Beam CT system with large FOV for Head and Neck imaging

By 30th January 2014No Comments

Particularly suitable for in-office use the new Scanora 3Dx cone beam CT system from Soredex has a large field of view (FOV) and is designed for head and neck imaging. The system is intended for wide application areas ranging from single dental implant planning with small FOV up to whole skull imaging with extra large FOV. The system is thus ideal for ENT, dentomaxillofacial and cranial examinations in imaging centers, ENT offices, total care oral and maxillofacial clinics and hospitals.


The new system is the latest member of the company’s SCANORA CBCT product family. Compared to its predecessors, however, the SCANORA 3Dx has a larger flat panel detector that now enables a wider range of imaging fields-of-view. The new highly accurate system has the same smooth workflow as in other models in the range and features a clear control screen and motorized patient positioning movements. The optional dental panoramic sensor is available as before.


A total of eight user selectable FOVs are available, each with their own typical applications. For example the smallest cylindrical FOV 50 x 50 mm with the highest resolution of 0.1 mm voxel size is intended for localized problems, such as detailed imaging of single tooth endodontic structures or ossicular chain of the inner ear, whereas several medium-size FOVs are suitable for imaging for example both temporal bones in one volume. The most suitable FOV for sinus and ENT imaging is the 140 x 165 mm (HxD) with 0.2 mm voxel size and finally the largest FOV 240 x 165 mm (HxD) with 0.5 mm voxel size is intended for whole skull examinations, such as in the follow-up of facial surgery operations. The voxel volume is isotropic, ensuring that measurements in any direction are accurate. Scanora 3Dx incorporates the latest imaging technology. For example, the 3D detector is a large amorphous Silicon flat panel for high resolution projection image acquisition and the SARA (SOREDEX Advanced Reconstruction Algorithm) reconstruction method produces 3D volumes out of these projection images. Thanks to the wide adjustment ranges of parameters the overall radiation dose for specific diagnostic indications can be optimized by selecting the smallest FOV for each task and adjusting the mA and resolution accordingly.
