A Duke University, EEUU, em colaboração com a Universidade Nova de Lisboa, tem estado a desenvolver estudos não-invasivos para o tratamento do cancro da bexiga através da técnica de hipertermia. Neste estudos a equipa tem utilizado o programa ANSYS EM para simulação de fontes de radiação (antenas) na gama das microondas.
Duke University, in collaboration with New University of Lisbon, are working on a noninvasive treatment for bladder cancer, using murine tumor models to investigate heat-activated delivery of chemotherapeutics. The team used ANSYS EM tools to design a miniature water-loaded microwave antenna. The simulated power deposition pattern was incorporated in CFD to model the effect of biological mechanisms such as blood perfusion and metabolism, which are critical to heat-transfer analysis of biological systems. To avoid overheating in skin, the antenna was cooled with a circulating fluid. The physics analyses were coupled to optimize selective heating of the bladder region. By integrating the simulations at an early stage, it was possible to optimize the heat applicator without repetitive experimental testing, consequently reducing the product lifecycle and associated costs.
