Radiology7:3D Imaging in Dentistry

These flashcards cover essential vocabulary and concepts related to 3D imaging in dentistry, aimed at helping students prepare for their examinations.

3D Imaging

A technology that creates three-dimensional representations of dental and facial structures.

CBCT

Cone Beam Computed Tomography; a 3D imaging technology used in dentistry to capture accurate bone anatomy.

Voxel

The smallest distinguishable box-shaped part of a three-dimensional space, representing a value on a 3D grid.

Effective Dose

A measure used to estimate the risk of radiation exposure to human tissues, expressed in sieverts (Sv).

Patient Movement

An obstacle in imaging that can increase artifacts and decrease accuracy in scans.

FOV

Field of View; the extent of the observable area captured in the imaging process.

Artifact

An undesirable feature in an image caused by errors in data capture or processing.

3D Visualization

The ability to view anatomy in three dimensions, improving accuracy in diagnosis and treatment planning.

Background Radiation

The natural radiation present in the environment, measured in microsieverts (μSv).

Dosimetry

The calculation and assessment of the radiation dose received by the human body.

Segmentation

The process of separating distinct structures in an image for analysis and treatment planning.

3D

accuracy and dimentions create an improved diagnosis

facts!!

one scan is multiple images

accurate

1:1 measure

3D

myths

New tech

high dose

dont gain info

disrupt workflow

patients dont want

true obstacles

initial cost

learning curve

workflow

patient movement

increased artifacts

intraoral

excellent for bone at an implant site

doesnt give width height angle location

panoramic 

screening tool 

has distortion,mag, ghost, superimposition, operator error

CBCT

cone beam computed tomography

cbct

volumetric imaging /3D imaging

voxel 

pixel with a 3D edge 

organized by size location and value

smaller voxel size 

means better resolution 

bit depth of computer

number of shades of gray your computer can compute

2^ whatever bit#

axial sections

coronal sections

saggital slicing

transaxial sections

segmenting the CBCT imaging

3d modeling of bone used for planning 

pathology preventing tooth eruption
