INTRODUCTION Ultrasound-guided interventions often necessitate scanning of deep-seated anatomical structures that may be hard to visualize. Visualization can be improved using reconstructed 3D ultrasound volumes. High-resolution 3D reconstruction of a large area during clinical interventions is challenging if the region of interest is unknown. We propose a two-stage scanning method allowing the...

Ultrasound of cranial nerves is a novel subdomain of neuromuscular ultrasound (NMUS) which may provide additional value in the assessment of cranial nerves in different neuromuscular disorders. Whilst NMUS of peripheral nerves has been studied, NMUS of cranial nerves is considered in its initial stage of research, thus, there is a need to summarize the research results achieved to date. Detaile...

Recently, the robotic ultrasound system has become an emerging topic owing to widespread use of medical ultrasound. However, it is still a challenging task model and transfer skill from physician. In this paper, we propose learning-based framework acquire scanning skills human demonstrations. First, are encapsulated into high-dimensional multi-modal in terms interactions among images, probe pos...

-This study demonstrated techniques for visualization of detailed brain anatomy with two dimensional ultrasound. The use of large aperture focused ultrasound transceivers appears to be essential for displaying the outlines of thalamus, internal capsule and substantial nigra in addition to those of the ventricles. The ability to vary grey scale and edge enhancement using either linear or logarit...

Late complications following endovascular aneurysm repair indicate the need for long-term surveillance. Clinical trials involving endoluminal stent grafts have typically used computed tomography angiography as the main imaging modality for surveillance. However, computed tomography angiography exposes the patient to higher levels of ionizing radiation, nephrotoxic agents, and increased cost com...
