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.

A compensating filter could be thought of as (con.):

Wedge Filter Closed Position

Wedge Filter Open Position

Inserting the filter into the Collimator
