Fundus image mosaicking for computer-assisted slit lamp imaging
Introduction:
The slit lamp biomicroscope is one of the most commonly used devices for retinal inspection, specially for the treatment of the eye periphery. However, only a small portion of the retina can be visualized through the biomicroscope, complicating the task of localizing and identifying surgical targets, increasing treatment duration and patient discomfort. In order to assist surgeons, we propose a method for creating intra-operative retina maps for view expansion using a slit-lamp device.

Hybrid Tracking and Mosaicking for Intra-operative Information Augmentation in Retinal Surgery
Introduction:
Current technical limitations in retinal surgery hinder the ability of surgeons to identify and localize surgical targets, increasing operating times and risks of surgical error. We developed a hybrid tracking and mosaicking method for augmented reality in retinal surgery. The system is a combination of direct and feature-based tracking methods. Several experiments conducted on phantom, in vivo rabbit and human images attest the ability of the method to cope with the challenging retinal surgery scenario. Applications of the proposed method for tele-mentoring and intra-operative guidance are demonstrated.
