Den 112 - Ch 27 3D imaging, End of Chapter quiz

Term used to describe computer-assisted digital imaging in dentistry; this imaging technique uses a cone-shaped x-ray beam to acquire information and present it in three- dimensions.

Cone-beam computed tomography

The number of gray-scale colors available to be chosen for each pixel in the image

Contrast Resolution

A vertical plane that divides the body into anterior and posterior sides; runs perpendicular to the ground

Coronal Plane

The universal format for handling, storing, and transmitting three- dimensional images

DICOM data

The reconstruction of raw data into images when imported into viewing software to create three anatomic planes of the body

Multiplanar Reconstruction

A vertical plane that divides the body into right and left sides; runs perpendicular to the ground

Sagittal Plane

A measurement of pixel size in multiplanar reconstruction

Spatial Resolution

Compared with traditional computed tomography procedures, cone-beam imaging provides a higher radiation dose for the patient.

false

An area of high attenuation that could stop radiation from reaching the receptor could include which restorations?

All of the Above

The fact that the cone beam data has a 1:1 relationship with the anatomy means that:

All of the Above

Cone-beam data has a 2:1 relationship with the anatomy.

False

The area that can be captures when preforming imaging procedures

Field of view

A three-dimensional shape that is created from two-dimensional images

Three dimensional volume rendering

A disadvantage of use of cone-beam data is that many dental professionals who incorporate CBCT into their practices have not had the training required to interpret anatomy beyond the maxilla and mandible.

True

A short exposure time decreases the chances for motion artifacts to occur and encourage a high-level of patient cooperation

True

If the field of view is small, findings or pathology in other regions of the oral and maxillofacial complex may be missed

True

Three-dimensional Imaging serves a number of diagnostic purposes for dental practitioners

True

Three-dimensional imaging provides an in-depth image that gives dental professionals a more complete interpretive image than two-dimensional scans of traditional imaging

True

Which is/are the advantages of CBCT imaging?

all of the above

The smallest element of a three-dimensional image

voxel
