More and more radiology practices are using the added value provided by CBCT as a supplement to CT. The advantages of CBCT are better detailed images because of much smaller voxel sizes, lower slice thickness, minimal artifacts and lower radiation dosage. Radiology combines the areas of indications of ENT, plastic surgery, skull base surgery, ophthalmology, maxillofacial surgery, and dental applications. Due to its ability to capture a variety of image volumes (fields of view or FOV), it can be used in temporal bone diagnosis; providing high definition images of the superior semicircular canal dehiscence, otosclerosis, ossicular chain dislocation, cholesteatoma, as well as images suitable for navigation systems.

Our solution.
The CBCT scanner, 3D Accuitomo 170, is an ideal imaging system for your radiology practice. It provides detailed views of very fine anatomical structures in the areas of the head and neck, such as the temporal bone, paranasal sinus, eye sockets, jaw and skull base. Consequently, it can be used for ENT, plastic surgery and all dental indications.

Benefits of the technology
Safe diagnosis
Three-dimensional imaging has one significant advantage: it can visualize anatomical structures in high definition. Hence, the doctor can obtain more data from the information because the true location of anatomical structures can only be discerned with a three-dimensional visualization. Accordingly, it helps make for safer diagnoses.
Reduction of radiation dosage
Patients also benefit from a CBCT scan because the radiation dosage is significantly lower than that of a conventional CT. In the latter case, the radiation source scans the region of the body that is to be examined in slices of 0.5 to 3.0mm; CBCT scans the entire section in one single rotation. As a result, the dosage is reduced by up to 80 percent as compared to a standard CT X-ray*.

Technology
Spatial orientation based on cone-shaped X-ray beam
CBCT works on the basis of a cone-/pyramidal-shaped X-ray beam: for this purpose, a flat panel detector and an X-ray source are mounted on opposite sides of a rotating arm. The physician positions the patient in the isocenter, and the C-arm rotates at least 180° during the scanning process. While the scanner is rotating around the patient, the projection of a cylindrical volume is obtained at defined view angles with the cone-shaped X-ray beam.
