1
Q
Third generation CT scanners
A
The use of a wide fan beam and detector bank which rotated around the patient
[MOST modern scanners]
2
Q
CT technique involves…
A
sectional imaging of the patient in the axial plane alongside the theory of image reconstruction whihc requires huge computing power
3
Q
CT equipment
A
- X-Ray tube
- High voltage generator
-Collimator
-Detector array
→ are mounted on a rotating gantry
4
Q
Axis of Rotation for CT
A
Z axis
5
Q
What happens to x rays in CT
A
X-rays are collimate to produce a wide fan beam so to cover the full cross section of the patient (50 degrees)
6
Q
How does the gantry rotate?
A
Using an induction motor or it is belt driven
