Answer:
The options
A. Additional cables
B. Slip rings
C. Multiple rows of detectors
D. Electron beam CT.
The CORRECT ANSWER IS B.
B. Slip rings
Step-by-step explanation:
During the 1990s, the use of slip ring technology promoted consecutive rotation of the x-ray tube (via removal of cables) and concurrent couch locomotion.
The Sixth-generation CT scanning is referred to as helical (or spiral) CT—allowing procurement of volume multislice scanning.
Today's helical multislice scanners, makes use of thousands of detectors (around 60+ rows), can derive continuous data procurement of 128 "slices" per tube rotation and can undergo 3D multiplanar reformation (MPR).
Fifth-generation CT employs electron beam; as the ultra high-speed CT is employed majorly for cardiac imaging.
