Simulation of breast tissue: a study to evaluate optimal compression dynamics

This investigation aims to study the behavior of breast tissue under different compression in a chamber prototype to differentiate strain between breast tumors and its surrounding tissues. The simulation study gives us the optimal compression pressure range to apply in order to have a measurable amount of strain and also to look at strain distribution dynamics if more than one cancer nodules are encountered. The result of these measurements enables the study to identify the correct compression pattern and chamber design for breast tissues. By doing this, it is hoped that the development of automated instrumentation of ultrasound elastography for the differentiation between normal and malignant breast tissues, utilizing B-mode ultrasound would be able to be established.
