Exam 26: Three-Dimensional Digital Imaging

Cone beam computer tomography utilizes a vertical, narrow x-ray beam, similar to panoramic radiography, to acquire three-dimensional information. The source of radiation in the CBCT machines rotates around the head of the patient.

With CBCT, the divergent rays exit the machine and some of the radiation is attenuated by the patient. In this statement, attenuated means :

A short exposure time for the CBCT, ____ the chances for motion artifacts to occur, as well as ____ patient cooperation.

The specialized equipment necessary for three-dimensional imaging that accepts the raw data and converts it to a stack of axial images called DICOM images is called the

Studies have compared the radiation dose of a typical CBCT scan to the radiation dose received from ____.

Many dental professionals who incorporate CBCT into their practices have not had the training required to interpret anatomy beyond the maxilla and mandible. What steps can be taken to correct this deficiency that could potentially hinder the use of CBCT?
