Advances in computer technology have enabled the development of new tools to support surgeons in the field of medical imaging and computer-assisted surgery. These tools assist the physician in the diagnosis, planning and execution of the surgical intervention. Among them, the neuronavigator stands out as a state-of-the-art tool that has replaced traditional procedures in many hospitals around the world. The present research is based on the need to generalize this procedure throughout the country. This work is focused on solving the problem of increasing the spatial information received by the surgeon with respect to the patient's anatomical information in the planning stage. The objective is to implement a software component for the surgical planning tool of a neuronavigator that is capable of visualizing a 3D volume reconstructed from the patient's DICOM images.
