Fast and Robust Localization of Surgical Array using Kalman Filter
Md Ashikuzzaman, Noushin Jafarpisheh, Sunil Rottoo +2
Intraoperative tracking of surgical instruments is an inevitable task of computer-assisted surgery. An optical tracking system often fails to precisely reconstruct the dynamic loca…
Virtual Source Synthetic Aperture for Accurate Lateral Displacement Estimation in Ultrasound Elastography
Morteza Mirzaei, Amir Asif, Hassan Rivaz
Ultrasound elastography is an emerging noninvasive imaging technique wherein pathological alterations can be visualized by revealing the mechanical properties of the tissue. Estima…
Ultrasound Scatterer Density Classification Using Convolutional Neural Networks by Exploiting Patch Statistics
Ali K. Z. Tehrani, Mina Amiri, Ivan M. Rosado-Mendez +2
Quantitative ultrasound (QUS) can reveal crucial information on tissue properties such as scatterer density. If the scatterer density per resolution cell is above or below 10, the…
Plane-Wave Ultrasound Beamforming Through Independent Component Analysis
Sobhan Goudarzi, Amir Asif, Hassan Rivaz
Beamforming in plane-wave imaging (PWI) is an essential step in creating images with optimal quality. Adaptive methods estimate the apodization weights from echo traces acquired by…
Semi-Supervised Training of Optical Flow Convolutional Neural Networks in Ultrasound Elastography
Ali K. Z. Tehrani, Morteza Mirzaei, Hassan Rivaz
Convolutional Neural Networks (CNN) have been found to have great potential in optical flow problems thanks to an abundance of data available for training a deep network. The displ…
Fine tuning U-Net for ultrasound image segmentation: which layers?
Mina Amiri, Rupert Brooks, Hassan Rivaz
Fine-tuning a network which has been trained on a large dataset is an alternative to full training in order to overcome the problem of scarce and expensive data in medical applicat…
Automatic Frame Selection using CNN in Ultrasound Elastography
Abdelrahman Zayed, Guy Cloutier, Hassan Rivaz
Ultrasound elastography is used to estimate the mechanical properties of the tissue by monitoring its response to an internal or external force. Different levels of deformation are…
Breast lesion segmentation in ultrasound images with limited annotated data
Bahareh Behboodi, Mina Amiri, Rupert Brooks +1
Ultrasound (US) is one of the most commonly used imaging modalities in both diagnosis and surgical interventions due to its low-cost, safety, and non-invasive characteristic. US im…
