Half-time seminar Monday 22 Apr | Can Deniz Bezek: Speed-of-Sound as a Novel Quantitative Imaging and Characterization Method Location: ÅNG 100155 ,Theatrum Visuale , Time: 14:15
Abstract:
In this talk, I will first present a method for estimating a single representative SoS value for the entire imaged tissue. This allows for biomechanical characterization, e.g., for breast density classification that is valuable as breast cancer risk factor. Next, I will talk about image reconstruction methods for mapping local SoS distribution, based on observed echo shifts from different viewing directions. We solve an inverse problem of image reconstruction based on a forward imaging model. Such forward models are typically hand-crafted based on the understanding of involved medical physics, electrics, and computational phenomena. We introduce a novel approach for learning such reconstruction forward model based on data. I will also present SoS imaging using model-based deep learning via loop unrolling as well as its pruning through distilled priors. |
