Three-dimensional imaging improves surgical performance for both novice and experienced operators using the da Vinci Robot System
ABSTRACT This study was designed to evaluate the impact of 3-dimensional vision on the performance of resident and experienced surgeons using the da Vinci Robot System (Intuitive Surgical, Sunnyvale, CA).
Four tasks were performed by 12 surgeons with varying experience. Performance times and errors were recorded using both 2-dimensional and 3-dimensional vision for each task.
Performance time and error rates for all 4 skills confirm a significant advantage using 3-dimensional vision. Performance times were reduced by 34% to 46% using 3-dimensional imaging for all participants with statistical significance. Error rates were reduced by 44% and 66%.
Independent of the biomechanical advantages of the da Vinci Robot System, 3-dimensional vision allows for significant improvement in performance times and error rates for both inexperienced residents and advanced laparoscopic surgeons.

- "Similarly, operative time interval for other procedures of two groups was compared [Table/Fig-3]. As single surgeon carried out all the procedures, a comparative evaluation was made in terms of operative imaging parameters like image quality, depth of perception, operative strain including laparoscopic surgeons surmount this by extracting 'pictorial' depth cues from conventional images  .

ABSTRACT: In this paper we review empirical studies concerning the effectiveness of stereoscopic displays in medicine. The domains covered in this review are: diagnosis, pre-operative planning, minimally invasive surgery (MIS) and training/teaching. For diagnosis, stereoscopic viewing of medical data has been shown to improve the sensitivity of tumor detection in breast imaging, and to improve the visualization of internal structures in 3D ultrasound. For MRI and CT data, where images are frequently rendered in 3D perspective, the added value of binocular depth has not yet been convincingly demonstrated. For MIS, stereoscopic displays decrease surgery time and increase accuracy of surgical procedures when the resolution of the stereoscopic displays is comparable to that of 2D displays. Training and surgical planning already use computer simulations; more research however is needed to assess the potential benefits of stereoscopic displays in those applications. Overall, there is a clear need for more empirical evidence that quantifies the added value of stereoscopic displays in medical domains.Research in Science Education 01/2012; 3(01).

Conference Paper: Synthesis of stereoscopic views from monocular endoscopic videos[Show abstract] [Hide abstract]
ABSTRACT: Recent studies have shown that 3D imaging provides some unique advantages over traditional 2D imaging for minimal invasive surgery. However, most existing endoscopes still use single-lens cameras, and the use of dual-lens 3D imaging techniques is still limited. This paper proposes an approach to enabling 3D imaging from a single-lens endoscope by automatically synthesizing stereoscopic views from monocular images captured by the endoscope. We first formulate the problem by introducing the notion of normalized disparity, based on which we show that affine reconstruction is sufficient for stereoscopic view synthesis. With this formulation and exploiting other domain-specific constraints, we then propose a robust structure-from-motion algorithm for a sparse set of feature points and a fast, linear interpretation algorithm for creating a dense disparity field for synthesizing stereoscopic views from original monocular video. Both synthetic images and real endoscopic videos are used to evaluate the proposed method. The results demonstrate the feasibility and effectiveness of the proposed method.Computer Vision and Pattern Recognition Workshops (CVPRW), 2010 IEEE Computer Society Conference on; 07/2010
