The Doppler Flow Velocity System (DFVS) is a non-invasive, real-time pulsed Doppler measurement device for studying cardiovascular function in a variety of small animal models, such as mice and rats. The system is ideally suited to analyze the rapid heart rates found in these species, due to the high frequency and excellent temporal resolution. The data is acquired using a very small probe, 2-3mm in diameter, allowing for more accurate and reproducible data to be acquired. Holding the probe with a steady hand or mounted in a micromanipulator, researchers can acquire many systolic and diastolic cardiac function parameters, as well as parameters from peripheral vessels such as the carotid, renal, and femoral arteries, plus indices from the coronary vessels.

Sydney Mensen, MSc
Sydney holds a Master of Management of Applied Sciences, specializing in Biological Sciences, and a double major in Biology and Medical Sciences—both from the University of Western Ontario. She has completed several courses and laboratory work involving anatomy and physiology of mammals. Her professional career has involved the application of her detailed understanding of mammalian physiology to obtain and analyze scientific data using a variety of technologies, including ultrasound, MRI, and surgical equipment. Her current role at Scintica is to work with scientists to understand their needs and provide technologies that will help to achieve their research goals.
Tonya Coulthard, MSc
Tonya Coulthard holds an MSc from the University of British Columbia in Experimental Medicine. Throughout her academic training she focused on a variety of diseases ranging from prion to chronic obstructive pulmonary diseases. In her professional career she has worked with several imaging and medical device companies; in these roles she has interacted with researchers around the world covering a very diverse range of research applications. In her present role at Scintica Instrumentation Tonya manages our Imaging Division; in this role she works in supporting our customers in understanding the products offered and how these instruments help to meet their research needs.
