The issue of radiation exposure in multi-slice spiral CT is beyond the scope of this letter, but the question should be posed in principle: Under which conditions is the enhanced X-ray exposure
caused by crossings of beam trajectories with repeated exposure of the same tissue areas compensated by the advantages of multi-slice spiral CT, such as isotropy and high resolution volumetric data?
MyRay's three-layer sensors feature a thin fiber-optic plate to improve image definition and protect the silicon receptor from direct X-ray exposure
We do a better job of keeping track of the oil changes in our car than of the X-ray exposure
to our bodies.
We have evolved in an environment of constant X-ray exposure
79) and the mean number of sessions involving some form of X-ray exposure
The X-ray exposure
for a single DRS SecureScan exposure is only a small fraction of a medical X-ray and is about the same as the X-ray exposure
gained by about 5 minutes of flying at 35,000ft or 20 minutes of natural background radiation.
Cells that divide quickly are very sensitive to X-ray exposure
The researchers assumed there was no cut-off point below which X-ray exposure
cannot induce cancer.
Many patients with Crohn's disease are young, and receive repeated x-ray exposure
from serial enteroclysis examinations.
This increase in efficiency enabled a substantial reduction in x-ray exposure
levels without compromising image quality, and x-ray film manufacturers moved quickly to develop x-ray film that was sensitized to green light.
