Flow Meter (TTFM) and Laser Doppler are very useful for measuring blood flow through a cross-section of a blood vessel over a period of time. The blood flow measurement devices market is segmented by product (ultrasound devices (ultrasound doppler and transit-time flow meters) and laser ...

Named after Christian Doppler for the phenomenon he described, the principle of flow estimation by Doppler is simple: Flow is a product of the average velocity of the blood measured in the vessel of interest and the cross-sectional area of the vessel. Two forms of D-US devices exist. The ...

Medications like sildenafil (Viagra) in combination with nitroglycerin may cause blood vessel dilation and low blood pressure. Low Blood Pressure and Pregnancy Normal physiologic changes in pregnancy increase the intravascular space, especially in the first two trimesters, and can cause lower blood press...
1. the pressure of the blood against the walls of any blood vessel. 2. the term usually refers to the pressure of the blood within the arteries, or arterial blood pressure. This pressure is determined by several interrelated factors, including the pumping action of the heart, the resistance ...

Vessel diameter will also be monitored as it may reveal dilated collaterals due to celiac axis stenosis. To calculate total liver volumes, DICOM files of preoperative CT images (portal phases) were uploaded to the local server and then evaluated using 3D volumetric software AquariusNET (TeraRecon,...
