This document is the preface and table of contents for a digital atlas of cystoscopy images published by Dr. Jan Schönebeck and sponsored by Astra Tech AB. It provides an overview of the atlas, which contains approximately 800 cystoscopy photos illustrating the majority of findings that can be seen during cystoscopy exams. The photos are intended to help educate physicians and can be used for presentations, textbooks, articles and case reports. The preface describes how Dr. Schönebeck digitized his collection of over 1,500 cystoscopy slides in order to preserve them and make them more accessible for educational purposes.
