    ResumenEste art铆culo muestra el resultado de pruebas preliminares con librer铆as y entornos de desarrollo comerciales encaminados a la construcci贸n de una aplicaci贸n para navegaci贸n quir煤rgica en el 谩rea de laparoscopia, usando marcadores cuadrados y marcadores naturales extensibles a despliegues en dispositivos m贸viles y gafas de realidad virtual. Para la renderizaci贸n de los objetos 3D se us贸 el Game Engine Unity junto a librer铆as especializadas para la visi贸n por computador y realidad aumentada como OpenCV, Vuforia y Kudan. Las pruebas preliminares muestran resultados satisfactorios en el seguimiento de marcadores y en la construcci贸n de la informaci贸n aumentada 煤til para el cirujano.Palabras Claves: Aplicaciones m贸viles, cirug铆a laparosc贸pica, realidad aumentada.聽AUGMENTED REALITY WITH SQUARE AND NATURAL MARKERS FOR SURGICAL NAVIGATIONAbstractThis article shows preliminary tests with libraries and integrated development environments (IDE) aimed at building an application for laparoscopic surgical navigation using square markers and natural feature markers extensible to displays, mobile devices and virtual reality goggles. For the rendering of 3D objects, the Game Engine Unity was used together with specialized libraries for computer vision and augmented reality such as OpenCV, Vuforia and Kudan. Preliminary tests show satisfactory results in the tracking of markers and in the construction of augmented information useful to the surgeon.Keywords: Augmented reality, laparoscopic surgery, mobile applications

    An Augmented Reality Application for the Radio Frequency Ablation of the Liver Tumors

    No full text
    Hepatic cancer is one of the most common solid cancers in the world. As surgery of hepatic cancer is seldom applicable, different solutions have been found to cure this disease. One of these is Liver Radiofrequency Ablation. This technique consists in a needle insertion inside the liver parenchyma in order to reach the tumor and in an injection of a radiofrequency current to cause tumor cell necrosis for hyperthermia. The needle placement task is really difficult because surgeon uses ultrasound, CT or MRI two-dimensional image to guide the needle. In this paper we present an Augmented Reality system to help the surgeon to place the needle as best as possible; the application can also help the surgeon during the preoperative planning because it offers various visualization modality of 3D models of the patient's organs obtained from the medical image
