 INTRODUCTION

Summary

This article presents a computer-aided system for performing minimally invasive surgical procedures (laparoscopies, punctures or interventional therapies). The software segments 3D shapes from DICOM images (CT, MRI, ultrasound), enabling precise localization and measurement of organ and lesion volumes. It can thus be used for diagnosis and treatment evaluation. The projection of 3D segmentations onto the patient's body, and the tracking of tools based on advanced image processing, significantly aid the practitioner in performing the surgical act.

Abstract

This paper presents new software to help in performing surgical acts (laparoscopies, punctures and interventional therapies). It realizes 3D segmentations from DICOM images (CT, MR US slices) leading to a precise localization and volumes measurements of organs and lesions which helps in the diagnostic and follow up of patients. The program allows projecting the organs and lesions shapes, realistically reconstructed and scaled, over the patient's body, using a standard video projector. Moreover the automatic tools tracking, using an image advanced process, give the surgeon the necessary feedback to control the surgical act.
