Opis

This unique workbook can be used as a stand-alone text or supplemental text for any course designed to enhance the work of radiologic technology students. It will also serve the needs of graduate radiographers as well as the physician in learning specific areas of the Fluoroscopic Image Intensifier such as:

Recenzje

". . . written primarily for students enrolled in radiography training programs. . . appealing because few radiographic textbooks provide a . . . discussion of the cameras and closed-circuit television systems used in fluoroscopic imaging."

Review:
"I highly recommend this book for use by any student or professional seeking to improve their understanding."
