    A novel, inexpensive method of image coregistration for applications in image-guided surgery using augmented reality
    (OXFORD UNIV PRESS INC, 2007) Lovo, Eduardo E.; Quintana, Juan C.; Puebla, Manuel C.; Torrealba, Gonzalo; Santos, Jose L.; Lira, Isidro H.; Tagle, Patricio
    OBJECTIVE: Augmented reality (AR) is a technique in which an overlay of a virtual image to a live picture is performed to create a new image in which both original images coexist as a single image. This results in the visualization of internal structures through overlying tissues. The objective was to describe an easy, inexpensive, and successful method to coregister with AR in an image-guided surgery setting using the resources at hand.

    Surgery for high-grade gliomas in a developing country: survival estimation using a simple stratification system
    (ELSEVIER SCIENCE INC, 2008) Lorenzoni, Jose; Torrico, Alejandro; Villanueva, Pablo; Gederlini, Alessandra; Torrealba, Gonzalo
    Background: In spite of great technological advances in diagnostic and therapeutic tools, Survival in patients with HGG has not changed significantly in the last years. Judicious management in each case needs Survival estimation after surgery. We used a simple stratification system evaluating the histology, patient's age, and the KPS.
