Autorenporträt

Paul C. Lebby has over 20 years of experience in integrating brain imaging into his clinical practice, beginning with the interpretation of images on sheets of film and progressing to current high-tech procedures. He has a background in computer graphics, which he has used to facilitate his teaching of neuroanatomy and neuropathology to students for more than two decades. He lectures across the country on the clinical use of brain imaging for those who treat patients with central nervous system conditions.
