  1. Filters in Pediatric Radiology Dan FerlicR.T. (R) http://www.ferlicfilter.com/index.php

  2. A compensating filter could be thought of as: • 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.

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