a way of conforming the x-ray beam to the shape of the anatomy.
a way of correcting the distribution of x-ray beam.
a way of reducing unnecessary exposure to the patient.
an instrument to reduce radiation (ex. the especially sensitive thyroid gland of the child).
a way of reducing primary to the correct level of exposure for an anatomical part where there is a large variation in thickness.
A compensating filter could be thought of as:

a method to reduce scatter radiation. a coning device. a method to improve grid performance. a method to reduce repeats. an instrument to benefit the patient
providing best practice healthcare. a method to increase diagnostic
information. A simple, practical device which saves time
and improves patient outcomes.
