Building Imaging Applications with Java™ Technology

Lawrence H. Rodrigues is a lead applications architect who was an early adopter of the Java programming language. During more than 20 years in industry, he has designed and developed several real-world applications in the fields of medical imaging, satellite imaging, and Internet imaging, including state-of-the-art imaging software for CT and MR scanners for a leading medical imaging company. Larry writes and lectures extensively and is also the author of The Awesome Power of JavaBeans™ (Manning, 1998). 0201700743AB05072001
