Invasive tumors differ from indolent tumors in both biological and physical characteristics. Recent developments have shown that progression from low-grade ductal carcinoma in situ (DCIS) to invasive ductal carcinoma (IDC) is associated with increasing collagen deposition, linearization, and bundling. These biological changes result in stiffening of the extracellular matrix, and consequently, results in small-scale changes in the elastic properties of the tissues. High-resolution ultrasound imaging of the breast can provide valuable information about these quantitative small-scale elastic changes. Here, I present the application of the 3D Full Waveform Inversion (a.k.a. Full Waveform Tomography), a high resolution imaging technique, to a laboratory acoustic data that we acquired with high spatial distribution of ultrasound sensors. I also present our learnings on the importance of key parameters in obtaining reliable images by Full waveform Inversion.

Dr. Farnoush Forghani Arani

Postdoctoral Researcher at Colorado School of Mines

Farnoush Forghani received her PhD degree in Geophysics from Colorado School of Mines in 2013. Her undergraduate training in Atomic Physics and her graduate research in signal processing, along with her professional work on imaging have exposed her to the practice of imaging as well as the challenges faced and knowledge gaps. After her brief experience of working in the energy sector, she decided to follow her passion and pursue a career in biomedical imaging. Currently, Farnoush is a postdoctoral researcher at the Colorado School of Mines, conducting research on the application of Full Waveform Tomography to ultrasound breast imaging. Farnoush’s career goal is to become a biomedical imaging researcher & educator and find practical and effective solutions to improve the imaging of the human body with particular emphasis on cancer imaging.
