Refraction-corrected ray-tracing methods in Ultrasound Transmission Tomography (USTT) are able to reconstruct the acoustic properties of tissues with good accuracy when using medium and high frequencies (>3MHz). However, these techniques, such as the Fast Marching Method (FMM), are time-consuming. In this work, we propose a real-time reconstruction methodology that exploits the large computing...

Breast ultrasound tomography can produce a map of acoustic properties through the breast, greatly increasing the potential for improved cancer diagnosis. The use of ultrasound is cheaper than MRI and safer than traditional mammography. One particular challenge seen in breast ultrasound tomography is the low resolution caused by ray behaviour commonly assumed in most reconstruction algorithms;...

Full-waveform inversion (FWI) is an iterative algorithm that produces high-quality images from experimental data. The petroleum industry has invested large sums to make this method more efficient, robust and reliable, especially for complex and large 3D datasets. However, its application to medical imaging, especially in 3D, is still in its infancy. Our objective is to efficiently implement...
