ABSTRACT
This paper presents the Fantatrope, an improvement of the pre-cinematographic devices such as the zoetrope, which creates a comfortable 3D display with the addition of ultra-realistic full-color holograms. The Fantatrope is built with a set of holograms of 3D-printed figurines mounted on a cylinder rotating at constant speed. A stroboscopic RGB LED lamp synchronized with the rotation successively illuminates the different frames and the recorded character is animated like in a stop-motion movie. All principal functions of this new device can be adjusted and this paper evaluates its performances. The operation of the Fantatrope is successfully demonstrated and shows the effect of a true 3D display without the need for special glasses or other viewing aids.
ABSTRACT
In urology technologies and surgical practices are constantly evolving and virtual reality (VR) simulation has become a significant supplement to existing urology methods in the training curricula of urologists. However, new developments in urology also require training and simulation for a wider application. In order to achieve this VR and simulation could play a central role. The purpose of this article is a review of the principal applications for VR and simulation in the field of urology education and to demonstrate the potential for the propagation of new progressive treatments. Two different cases are presented as examples: exposure therapy for paruresis and virtual cystoscopy for diagnosis and surgery of bladder cancer. The article uses research and publications listed in openly accessible directories and is organized into 3 sections: The first section covers features of VR and simulation technologies. The second one presents confirmed applications of current technologies in urology education and showcases example future applications in the domain of bladder treatment and surgery. The final section discusses the potential of the technology to improve health care quality.
ABSTRACT
Recent developments in virtual, augmented, and mixed reality have introduced a considerable number of new devices into the consumer market. This momentum is also affecting the medical and health care sector. Although many of the theoretical and practical foundations of virtual reality (VR) were already researched and experienced in the 1980s, the vastly improved features of displays, sensors, interactivity, and computing power currently available in devices offer a new field of applications to the medical sector and also to urology in particular. The purpose of this review article is to review the extent to which VR technology has already influenced certain aspects of medicine, the applications that are currently in use in urology, and the future development trends that could be expected.
