We do not make specic 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’ specications and the needs of
your radiologists and physicists before developing your CT quality assurance program.
