The Varia Transcranial Doppler Ultrasound (TCD) device provides precision measurements of cerebrovascular blood flow. Designed to exacting standards, Varia delivers excellent signal quality with minimal ambient noise, allowing clinicians to easily locate vessels and obtain high-quality measurements. When attached to an external MS Windows-based computer, Varia presents the clinician with an intuitive interface including clear displays and easy-to-use input parameters to facilitate a quality exam.Utilized with software only device accessory Varia-NCI.
A mains electricity (AC-powered) device assembly consisting of a desktop unit, a graphical display unit and an attached probe or interchangeable probes, designed to noninvasively locate and assess the extent of vascular flow restriction (e.g., clots, stenosis, mechanical damage) by measuring blood flow rate using ultrasound/Doppler/transit time technology. Clinical applications include venous/arterial flow screening (e.g., assessment of air embolism, atherosclerosis, varicose veins, venous thrombosis), ankle pressure index, and/or blood flow wave form recording.
