Attenuation correction in PET scans is actually aimed at accounting for the differences in the attenuation of the radiation signatures exhibited by different tissues because of the losses that materials impose on radiation passing through it. There are whole textbooks on this subject, and it is quite involved.

Pet correction spray is a can of compressed air that makes a loud hissing sound. This sound is supposedly a predator sounds made in nature which sends the right signal straight to the dogÕs brain telling it to stop. Correction spray can be used on any dog and is a harmless way of training your dog.
Yes the word 'correction' can be used in a sentence. The teacher instructed the student to make the correction before turning in the term paper. If a teacher makes a correction on a paper, she often uses red ink.
There is no attenuation due to absorption, but attenuation will occur due to divergence (spreading out) of the wave.
6 dB is a "good" attenuation.
We can reduce attenuation effects bt using repeaters
Attenuation means the reduction of signal strength during transmission. If one is looking for information about attenuation, it can be found on the Wikipedia website.
The significance of end correction is that it is used in the radiation acoustic impedance of a circular piston.

It depends on the repeater. Those that receive a signal, buffer it in real time and pass it on as a digital signal will reduce the effects of attenuation. Those that receive a signal and regenerate it with a new clock signal will generally eliminate the effects of attenuation completely.The type of repeater used depends on where and how it is used as well as the signal that is being transmitted.
