“…The addition of depth perception leads to a faster and better interpretation of the morphology of the patient's pathology and contextual anatomy. Stereoscopic images are being used in various clinical applications, such as surgical planning [1], surgical navigation [2]- [4], minimally invasive endoscopic surgery [5], autostereoscopic intracranial MRA visualization [6], and so on. Autostereoscopic visualization of the patient's anatomy has the potential to be combined with augmented reality, which has been reported to increase the surgical instrument placement accuracy [3].…”

We present an approach for efficient rendering and transmitting views to a high-resolution autostereoscopic display for medical purposes. Displaying biomedical images on an autostereoscopic display poses different requirements than in a consumer case. For medical usage, it is essential that the perceived image represents the actual clinical data and offers sufficiently high quality for diagnosis or understanding. Autostereoscopic display of multiple views introduces two hurdles: transmission of multi-view data through a bandwidth-limited channel and the computation time of the volume rendering algorithm. We address both issues by generating and transmitting limited set of views enhanced with a depth signal per view. We propose an efficient view interpolation and rendering algorithm at the receiver side based on texture+depth data representation, which can operate with a limited amount of views. We study the main artifacts that occur during rendering-occlusions, and we quantify them first for a synthetic model and then for real-world biomedical data. The experimental results allow us to quantify the peak signal-to-noise ratio for rendered texture and depth as well as the amount of disoccluded pixels as a function of the angle between surrounding cameras. Index Terms-3-D displays, biomedical imaging, depth image based rendering (DIBR), rendering quality, view interpolation.

“…The reduction of brightness of the parallax barrier display of the mobile workstation in 3D mode was disadvantageous compared with the lenticular grid display of the stationary workstation. In literature, the advantage of autostereoscopic 3D displays compared with 2D displays was shown on the example of angiographic data sets [1]. Compared with 3D displays using viewing aids, autostereoscopic displays were found to be beneficial [5,22], especially in the OR, where the use of viewing aids may be disadvantageous because of hygienic reasons [1].…”

A demonstrator system for planning neurosurgical procedures was developed based on commercial hardware and software. The system combines an easy-to-use environment for surgical planning with high-end visualization and the opportunity to analyze data sets for research purposes. The demonstrator system is based on the software AMIRA. Specific algorithms for segmentation, elastic registration, and visualization have been implemented and adapted to the clinical workflow. Modules from AMIRA and the image processing library Insight Segmentation and Registration Toolkit (ITK) can be combined to solve various image processing tasks. Customized modules tailored to specific clinical problems can easily be implemented using the AMIRA application programming interface and a self-developed framework for ITK filters. Visualization is done via autostereoscopic displays, which provide a 3D impression without viewing aids. A Spaceball device allows a comfortable, intuitive way of navigation in the data sets. Via an interface to a neurosurgical navigation system, the demonstrator system can be used intraoperatively. The precision, applicability, and benefit of the demonstrator system for planning of neurosurgical interventions and for neurosurgical research were successfully evaluated by neurosurgeons using phantom and patient data sets.

“…Nowadays, this limitation can be partly overcome by the use of 3D displays that significantly improve depth perception and the ability to estimate distances between objects. Therefore, the content creation process needs to be reconsidered For computer generated imagery, the rendering system can seamlessly render one or more related views depending on the application [Abildgaard et al 2010;Benassarou et al 2011]. 3D contents are obviously clearer and more usable than 2D images because they doe not involve any inference step.…”

Figure 1: Autostereoscopic technology allows 3D images popping out of the screen while natural interaction provides a seamless manipulation of 3D contents. AbstractA few years ago, the introduction of the WebGL API has allowed displaying 3D content in web browsers very efficiently by using the power of 3D accelerators. Nowadays, 3D web applications, from games to medical imaging, tend to compete with their desktop counterparts. Among the main factors that can improve the feeling of presence in terms of impressiveness, immersion and natural interaction play a prominent role in enhancing the quality of the user experience. Both immersion and natural interaction rely on dedicated hardware like 3D displays and tracking devices. Unfortunately, browser makers do not supply JavaScript mechanisms for accessing hardware for security reasons. In this paper, we propose a plugin-free solution using the new features of HTML5 (WebGL and WebSockets) in order to handle autostereoscopic displays and widespread tracking devices like IR depth sensors for providing immersion and natural interaction within the web browser.
