I have been an xray technologist since 1984. And I thought I knew everything about taking a chest xray...well, I did, back then. My department purchased this book last month and it is an eye opener! I read things in this book that I didn't know or had forgotten. The pictures are great, information priceless. If you are an 'old salt' like me or just a 'young pup' starting out, I highly recommend this book. You'll keep it with you throughout your career.
