“…Many studies, oriented at laparoscopic surgery research, employed virtual reality techniques [14,[16][17][18][19][20]. Most of these studies were explicitly occupied with the effect of visual display dimensionality (2D versus 3D) and visual display location on the operator (surgeon) performance [18][19][20] or task difficulty [16,17].…”

“…Most of these studies were explicitly occupied with the effect of visual display dimensionality (2D versus 3D) and visual display location on the operator (surgeon) performance [18][19][20] or task difficulty [16,17]. In one survey, expert surgeons indicated depth perception as an important technological challenge for improving laparoscopy systems although opinion is not conclusive regarding the importance of 3D display [17].…”

“…In a recent literature review, it was reported that for the inexperienced surgeon "loss of three-dimensional visual depth cues forms a major obstacle for the effective use of instruments, creating fundamental psychomotor problems of hand-eye coordination" [18, page 210]. On the other hand, empirical test of the benefit of 3D visualization showed significant decrease in performance, apparently due to technological insufficiency [19]. Zheng and colleagues, who conducted an experimental study of co-location presentation manipulation [20], conclude that collocated display could improve surgeon performance, relative to performance with dislocated presentation.…”

One of the more debated issues regarding training simulators is their validity for transfer of skills to sensory environments that differ from the simulator. In two experiments, the advantages of three-dimensional (3D) and collocated (Col) visual displays were evaluated in a realistic and complex visuomotor task. The two factors were evaluated independently, comparing Col-2D with dislocated-2D (experiment 1) and with Col-3D (experiment 2). As expected, in both cases the more immersive presentation condition facilitated better performance. Furthermore, improvement following training in the more immersive condition carried over to the following less immersive condition but there was no carry over in the opposing order of presentation. This is taken as an indication for the differential development of skills conditioned by the level of immersiveness of the training environment. This further suggests that learning of complex realistic tasks is not carried over from less immersive simulator to the complex sensory environment of reality, due to the large gap in sensory patterns.

“…Furthermore, current 3D displays, in particular the prolonged use of 'active' glasses systems, is associated with dizziness, headaches, nausea and visual strain [8]. The alternative 'passive' systems are easier to use, but the images are of poorer quality and dimmer than with conventional 2D systems [9]. Additionally, the dramatic improvement in 2D image display quality negated any advantages offered by the first-generation 3D systems [10].…”

“…The limited space for positioning two independent cameras within the body prevents truly 3D images. In a quantitative evaluation of tasks which are feasible in both monoscopic and stereoscopic systems, the stereoscopic system did not provide better task performance than a standard monoscopic laparoscopy system [25]. Thus the advantages of stereoscopic systems for their use in conventional laparoscopic interventions are put into question -there are some tasks however that can only be performed with a stereoscopic view.…”

A major roadblock for using augmented reality in many medical and industrial applications is the fact that the user cannot take full advantage of the 3D virtual data. This usually requires the user to move the virtual object, which disturbs the real/virtual alignment, or to move his head around the real objects, which is not always possible and/or practical. This problem becomes more dramatic when a single camera is used for monitor based augmentation, such as in augmented laparoscopic surgery. In this paper we introduce an interaction and 3D visualization paradigm, which presents a new solution to this old problem. The interaction paradigm uses an interactive virtual mirror positioned into the augmented scene, which allows easy and complete interactive visualization of 3D virtual data.This paper focuses on the exemplary application of such visualization techniques to laparoscopic interventions. A large number of such interventions aims at regions inside a specific organ, e.g. blood vessels to be clipped for tumor resection. We use highresolution intra-operative imaging data generated by a mobile Carm with cone-beam CT imaging capability. Both the C-arm and the laparoscope are optically tracked and registered in a common world coordinate frame. After patient positioning, port placement, and carbon dioxide insufflation, a C-arm volume is reconstructed during patient exhalation and superimposed in real time on the laparoscopic live video without any need for an additional patient registration procedure. To overcome the missing perception of 3D depth and shape when rendering virtual volume data directly on top of the organ's surface view, we introduce the concept of a laparoscopic virtual mirror: A virtual reflection plane within the live laparoscopic video, which is able to visualize a reflected side view of the organ and its interior. This enables the surgeon to observe the 3D structure of, for example, blood vessels by moving the virtual mirror within the augmented monocular view of the laparoscope.

Quantitative evaluation of three advanced laparoscopic viewing technologies: a stereo endoscope, an image projection display, and a TFT display

Abstract: Although the stereo viewing system promises improved depth perception and the TFT and image projection displays are supposed to improve hand-eye coordination, none of these systems provided better task performance than the standard viewing system in this pelvi-trainer experiment.
