CHAPTER 26: 3D DIGITAL IMAGING Flashcards
What year was the CBCT introduced ?
1999
what is CBCT?
Cone-beam computed tomography
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.
CBCT
The universal format for handling, storing, and transmitting three-dimensional images; the acronym refers to Digital Imaging and Communications in Medicine.
Dicom Data
The area that can be captured when performing imaging procedures.
Field of view (FOV)
The reconstruction of raw data into images when imported into viewing software to create three anatomic planes of the body.
Multiplanar reconstruction (MPR)
A horizontal plane that divides the body into superior and inferior parts; runs parallel to the ground.
Axial Plane
A vertical plane that divides the body into anterior and posterior sides; runs perpendicular to the ground.
Coronal plane
A vertical plane that divides the body into right and left sides; runs perpendicular to the ground.
A midsagittal plane describes a plane that runs through the midline of the body.
sagital plane
The number of gray-scale colors available for each pixel in the image.
resolution contrast
A measurement of pixel size in multiplanar reconstruction.
resolution spatial
An image that demonstrates the anatomy in three dimensions.
three dimensional digital imaging
A three-dimensional shape that is created from two-dimensional images.
three dimensional volume rendering
The smallest element of a three-dimensional image; also referred to as volume element or three-dimensional pixel.
Voxel
Anatomic features within the FOV provide accurate dimensional measurements of the patient with a : ratio relationship
