DOPPLER ULTRASOUND OF ORBITAL VESSELS [PDF]
Australian and New Zealand Journal of Ophthalmology, 1988 AbstractThe techniques of doppler ultrasound have been applied to blood vessels within the orbit. The doppler frequency shifts of ultrasonic pulses scattered from blood cells moving within orbital vessels are a measure of velocities rather than the amount of blood flow.

Arthritis Care &Research, EarlyView.Objective We aimed to validate the Pediatric Arthritis Ultrasound Scoring System (PAUSS) for upper extremity joints in children with juvenile idiopathic arthritis (JIA). Methods Children with JIA were evaluated for elbow, wrist, or finger arthritis by clinical examination (CE) and musculoskeletal ultrasound (MSUS) with images scored according to the ...

What is Doppler ultrasound? [PDF]
, 2011 The term Doppler should be capitalized because it refers to Christian Johann Doppler, an Austrian physicist (1803–1853). He described a phenomenon whereby the frequency of sound changes when it is reflected off a moving object.

Arthritis Care &Research, EarlyView.Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.

Hot‐Film and Calorimetric Methods With Transient Heating for Measurement of High Biofluid Flow Rate
Advanced Functional Materials, EarlyView.Accurate measurement of biofluid flow rate is vital for clinical diagnostics. We propose a transient heating strategy using short thermal pulses and peak temperature tracking to enhance the flow sensitivity of the hot‐Film and calorimetric methods. Simulations show how optimal heating time maximizes sensitivity across flow rates.
