Whether for medical or dental applications, the “CT” or computed tomography of both medical and dental CT scan machines offers unrivalled 3-dimensional clarity into and detail of a patient’s anatomy, inclusive of both hard and soft tissues such as bone and nerve pathways.
Still, there are some important differences between traditional medical and dental CT scan machines, which will be covered here.
Scanning Methodology
The chief difference between medical and dental CT scan machines has to do with how the machine actually collects a scan.
In the case of traditional computed tomography, a high-output, rotating anode X-ray tube is used to emit a fan-shaped X-ray beam that captures a series of slices of the patient, which then must be arranged and assembled to reconstruct a coherent image of the patient’s anatomy.
In the case of dental cone beam computed tomography, a cone-shaped beam is emitted and a solid-state sensor is used to capture the images. It can produce a whole volume image in a single rotation. In a dental CT scan machine, the X-ray tube used is a low-power fluoroscopy tube.
Diagnostic Accuracy
Dental cone beam computed tomography offers a potentially greater level of detail in capturing scans than traditional medical CT technology. CBCT is sensitive to very minor aberrations or subtle changes in anatomy that make it ideal for producing extremely detailed scans that are superior for making a rapid and accurate diagnosis.
Field of View Collimation
Many dental CT scan machines have adjustable field of view settings that can be collimated down to capture only the area of interest. This offers further flexibility with respect to the detail of the anatomy captured, as well as with overall radiation dosage.
