Low-Cost Methodology for Estimation of Breast Shape using Microwave Signals

The retrieval of the body shape can be crucial ahead of medical Microwave Imaging (MWI) reconstruction.Current state-of-the-art methods provide accurate estimations of the body shape but they require additional hardware and may be computationally intensive and time-consuming.In this paper, we propose a simple method using the original measurements of an MWI acquisition, and we assess the performance of the method under different conditions.The results show the estimation accuracy varies with the complexity of the shape under examination, antenna configuration and data source.The estimated median errors for some antenna positions were as low as 0.4 mm.An optimised estimation was obtained by fine-tuning parameters for each simulated or experimental scenario.
