In this paper, we introduce something about panoramic videos and the technology procedure of panoramic video, including video collection, progressing, transaction, playing etc. We designed a medicalteaching system based on panoramic video technology, and designed three different application scenes of medical teaching as panoramic video teaching in normal classes, panoramic video teaching in laboratories and panoramic medical teaching video on mobile devices after classes. Applying panoramic video technology on medical teaching makes a vivid show way of teaching videos. Users can watch the medical progress at any angle by handling the software or by using VR devices, both of which can improve the quality of teaching and save the teaching time at the mean time.
