Ultrasound (US) is one of the most widely used modalities for clinical intervention and
diagnosis due to the merits of providing non-invasive, radiation-free, and real-time images …

Improving the quality of image-guided radiation therapy requires the tracking of respiratory
motion in ultrasound sequences. However, the low signal-to-noise ratio and the artifacts in …

Purpose Ultrasound (US) imaging is an established imaging modality capable of offering
video‐rate volumetric images without ionizing radiation. It has the potential for intra‐fraction …

Objective: Intra-interventional respiratory motion estimation is becoming a vital component in
modern radiation therapy delivery or high intensity focused ultrasound systems. The …

Motion compensation in radiation therapy is a challenging scenario that requires estimating
and forecasting motion of tissue structures to deliver the target dose. Ultrasound offers direct …

Ultrasound is a promising medical imaging modality benefiting from low-cost and real-time
acquisition. Accurate tracking of an anatomical landmark has been of high interest for …

Needle insertion procedures under ultrasound guidance are commonly used for diagnosis
and therapy. It is often critical to accurately reach a targeted region, and this can be difficult …

We have previously developed a robotic ultrasound imaging system for motion monitoring in
abdominal radiation therapy. Owing to the slow speed of ultrasound image processing, our …

In this paper, we propose the ADVISEd (Active Deformation through VIsual SErvoing)
method, a novel model-free deformation servoing method able to deform a soft object …

Radiotherapy is a widely used treatment modality for various types of cancers. A challenge
for precise delivery of radiation to the treatment site is the management of internal motion …
