Real-time Ultrasound (US) image fusion with a pre-acquired second imaging dataset — Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and/or CT/PET — has become widely used in recent years for both diagnosis and image-guided interventional procedures. Liver and kidneys are the main focused anatomical districts, related to abdominal application. There are still nowadays some drawbacks, regarding...
Multigate Quality Doppler Profiles (QDP) is a Fast Fourier Transform-based Doppler technology recently integrated in a commercial ultrasound scanner. QDP represents a novel analysis tool, which is able to simultaneously detect and show the velocity components, present in the blood flow of multiple vessels, without any frame rate reduction. The present work describes QDP application to the measurement...
The study of the Internal Jugular Vein (IJV) hemodynamics has gained particular attention after the definition of Chronic Cerebrospinal Venous Insufficiency syndrome (CCSVI), and the discovery of highly debated possible links between the venous system and some neurological pathologies (Multiple Sclerosis, Cough Headache, Transient Global Amnesia). One of the most studied hemodynamic signs of the IJV...
The present work describes the ergonomics and usability preliminary tests regarding the human upper limb kinematics and cognitive evaluation of two diagnostic portable ultrasound scanners. The tests were performed by two sonographers (an expert one and a novice one) on one subject in abdominal and vascular clinical applications. The two portable systems had different user interfaces: one system had...
Chronic cerebrospinal venous insufficiency (CCSVI) is a vascular syndrome in which deoxygenated blood flow from the veins surrounding the brain and the spine is slowed or blocked in its return to the heart. Among the criteria adopted for CCSVI diagnosis, the detection of possible intermittently reversed (reflux) flow in deep cerebral veins and sinuses, is of major importance. However, conventional...
