Diagnostic quality always has been a primary concern in connection with therapy and treatment planning. Many practices still send their patients to a radiologist for a CT when they require 3D images, even though cone-beam computed tomography is a great way to provide this service in an ENT practice. In addition to the advantages of continuous workflow and retention of the fees in your practice, you will spare your patients unnecessary radiation doses as compared to the CTs extensively being used in the market.
The 3D Accuitomo 170 offers a minute voxel size of just 80 μm (micrometers). This super-fine voxel displays an amazing level of clarity enabling a comprehensive examination. The imaging area is cylindrical and the maximum size is 170 mm in diameter by 120 mm in height, which covers the majority of the head and neck region, suitable for specialized medical applications in otorhinolaryngology and the maxillofacial field.
Patients benefit from a CBCT scan, compared to a conventional CT scan, because the radiation dose is significantly lower. For a CT image, 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*.

How it works
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.
Why is a Technical Qualification Course necessary?
A Technical Qualification Course has to be completed to operate a CBCT system and to evaluate three-dimensional X-rays because only then will the physician be able to take CBCT X-rays and evaluate the images competently.
What does such a course entail?
The first module conveys technical instruction, "Taking skull X-rays for ENT indications", followed by technical instruction and proficiency modules in CBCT diagnostics. The CBCT Technical Qualification Course is held on two days respectively; however, there should be an interval of at least three months between the two course dates. Following regular attendance and successful completion of the final exam, the medical association will grant you the qualification to operate a CBCT system and evaluate three-dimensional X-rays.
