mAs - milliAmpere seconds

mAs stands for milliAmpere seconds.  It is the product of current (mA), and time in seconds.  Together, mAs dictates the QUANTITY of x-rays produced.  The amount of x-rays produced is proportional to mAs.  If you double your mAs, you double the number of x-rays produced. 


How does mAs affect density?

Density is the overall darkness or blackness of a radiographic image.
