Jennifer Janson, Amy Whittier, and Carol O’Connell from Elsevier Publishing were instrumental in providing support, guidance, and the resources in the redesign and publishing of the pocket handbook. We are most indebted to our former students, fellow technologists, and those many educators throughout the United States and Canada who challenged and inspired us. We thank all of you and hope this pocket handbook continues to be a valuable aid in improving and maintaining that high level of radiographic imaging for which we all strive.
