CBCT Basics Flashcards
Digital image processing/modifications include:
- compression
- imaging manipulations
- image reconstruction
Imaging manipulations = automated image analysis which includes:
Qualitative image analysis & Quantitative image analysis
Imaging manipulation that changes pixels digital value
qualitative
Imaging manipulation that counts the number of pixels:
quantitative
Data is utilized by other software programs and produces different image presentations:
Image reconstruction
Label the following views from the spiral CT Scan 3D image reconstruction:
- caudal cranial view
- buccal view
- distal view
- lingual view
- mesial view
- occlusal view
You don’t do a CBCT _____, you do a CBCT ____
Image; scan
Use of computers to generate multiple images of an object from digitized density information obtained from various signals; x-radiation (MDCT), (CBCT), magnetic fields (MRI), sonar radiation (ultrasound), etc.
Computed tomography
Two forms of x-ray CT:
- CBCT (Cone beam computed tomography)
- MDCT (Multi detector computed tomography)
CBCT and MDCT are both forms of:
x-ray CT
CBCT was developed in:
Japan Europe before 2000 A.D.
What was the first commercially available cone beam system in the U.S.?
NewTom (in 2001)
What version of Newtom was created in 2001?
NewTom 9000
NewTom 9000 was later renamed:
NewTom3G
NewTom 9000/ NewTom3G is similar to panoramic but captures:
density values of the whole object at different angles
NewTom 9000 (2001) is similar to the first:
MDCT in 1971
Describe the change of design from the NewTom3G to the NewTom VGi:
lay down versions –> stand up version
Label the names of the following machines:
Left: NewTom 3G
Right: NewTom VGi
How is the NewTom VGi EVO similar to a pano?
The patient stands while getting scanned
With the NewTom VGi EVO, the imaging capture process is _____ and the image processing is ____
short; longer

Orthophos
What models did I-CAT FLX Create?
V8, V10, V17
What is significant about I-CAT FLX V8, V10, and V17 models?
Sit down models
