Endoscopic ultrasonography (EUS) is a widely used imaging modality in gastroenterology. The development of linear-array endoscopic ultrasound transducers, with facilities for EUS-guided diagnostic and therapeutic procedures, led to increasingly widspread use in different areas of the body. Examiners need to have excellent knowledge of anatomy. Orientation in linear EUS is more difficult and the learning curve is long. In an effort to shorten the training, reducing the risk to the patient and to allow a faster learning of the basic anatomic structures EUS meets VOXEL-MAN, an interactive three-dimensional anatomic simulation programm has been developed for linear EUS for the purposes of private and independant study.
