Stroboscopy

Description

This book presents a complete picture of the art and science of stroboscopy. It includes comprehensive coverage of the imaging process, and also the disease process that exists in benign lesions, cancer, and neuropathology. Comparisons of normal images with pathologies are included to enhance reader's diagnostic skills, and the use of stroboscopic images before and after therapy to determine results enhances their clinical skills.  Read more...
