Damage to x-ray tubes that can shorten their useful life can occur with

B)repeated preparation of the tube several times before exposures are performed.
C)preselection of exposure factors before the tube is boosted.
D)both a and b.
All of the following are true of CR technology EXCEPT
A)there is no difference in image resolution among the three image plate (cassette)sizes.
B)the latent image is time sensitive and should be processed in the reader in a reasonable time period.
C)CR image plates need to be erased or "washed clean" with an intense light source in the reader assembly.
D)CR technology offers an affordable electronic transition toward digital imaging.
In a radiographic/fluoroscopic (R/F)system,the primary barrier is considered to be the
A)fluoroscopy lead apron in front of the spot film device.
B)image intensifier or flat panel detector.
C)tabletop of the R/F table.
