SIMULACIÓN DE LA CONDUCTIVIDAD DE MODELOS DE MAMA CON SOFTWARE COMSOL (SIMULATION OF CONDUCTIVITY OF BREAST MODELS WITH COMSOL SOFTWARE)
Resumen
El cáncer de mama constituye la primera causa de muerte por neoplasia en la mujer en el ámbito mundial. Nuevas técnicas de diagnóstico prebiopsia para uso global se han desarrollado en la última década para reducir el número de pacientes sometidos a procedimiento de biopsia innecesario. Este trabajo implementa la simulación en el software COMSOL Multiphysics para determinar la conductividad en modelos de senos con lóbulos de diferentes tamaños que simulan carcinomas. Para ello se propone tres anillos de 8 electrodos cada uno instalados sobre un molde que simula una copa del brasier. Las pruebas demostraron que se puede obtener un grado de éxito aceptable al momento de ubicar carcinomas con dimensiones mayores o iguales a 0.6 cm de diámetro, a una altura entre 0.2 cm y 3.95 cm con respecto de la base del modelo. Este trabajo abre las puertas a un proyecto futuro donde se puedan llevar pruebas en pacientes; ya que dispone una base para ejecutar las mediciones, que es lo que se debe de esperar y como interpretar los resultados obtenidos.

Abstract
Breast cancer is the leading cause of death from malignancy in women worldwide. New prebiopsy diagnostic techniques for global use have been developed in the last decade to reduce the number of patients undergoing the unnecessary biopsy procedure. This work implements simulation in COMSOL Multiphysics software to determine conductivity in breast models with lobes of different sizes that simulate carcinomas. To do this, three rings of 8 electrodes each are installed on a mold that simulates a bra cup. The tests showed that an acceptable degree of success can be obtained when locating carcinomas with dimensions greater than or equal to 0.6 cm in diameter, at a height between 0.2 cm and 3.95 cm with respect to the base of the model. This work opens the doors to a future project where tests can be carried out on patients; since it has a basis for executing the measurements, what to expect and how to interpret the results obtained.
Keywords: carcinoma, impedance, breast, simulation.
