Fetal heart rate (fHR) monitoring using Doppler Ultrasound (US) is a standard method to assess fetal health before and during labor. Typically, an US transducer is positioned on the maternal abdomen and directed towards the fetal heart. Due to fetal

Medical instrument segmentation in 3D ultrasound is essential for image-guided intervention. However, to train a successful deep neural network for instrument segmentation, a large number of labeled images are required, which is expensive and time-co

Viscosity has been shown to be a tissue property of diagnostic value that plays an important role in the propagation of shear waves. Recently, system identification (SI) techniques have been proposed for the estimation of tissue viscoelasticity maps.
