Digital cone-beam computed tomography in ENT

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 scan 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 revenue in your practice, you will spare your patients unnecessary radiation doses as compared to the MSCT extensively being used in the market.

  • High Clarity

    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.

  • Low Dose

    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.
