5 Introduction
The Phantom Laboratory and physicist, David J. Goodenough, Ph.D., are continually developing and researching new tests and modifications for the Catphan® phantoms.
The test objects that make up the current Catphan® models embody more than a
quarter century of scientific evaluation and field experience.  This manual outlines the applications of each module contained in the Catphan® 500 and 600 phantoms.
We do not make specific recommendations on the content of your quality assurance program, because each medical imaging facility has its own unique set of requirements.
A sample program is provided to give you ideas for possible program content.  We
suggest a review of local governing regulations, manufacturers’ specifications and the needs of your radiologists and physicists before developing your CT quality assurance program.
The Catphan® instructional video, which illustrates the phantom setup and scanning of
the different Catphan® sections, is also available.
