Electromagnetic flowmeter for medical physics flow studies

该提案是为了购买一个电磁流量计，该流量计将与粒子成像测速（PIV）系统和多普勒超声（DUS）研究系统一起用于各种与流动相关的研究。PIV和DUS系统可用于精确和精确地绘制流模式和流速，具有高空间和时间分辨率，可用于医学物理和软凝聚态物理。该流量计的主要用途是在模拟血管流动的物理模型中进行测量，例如通过有斑块积聚的动脉，以便更好地了解由于疾病进展而导致的血液动力学（血流）变化。该流量计将用于提供准确的在线测量和验证散装流量和流量。这些详细的流量研究需要一个不干扰被测量流量的流量计，并且对脉动流量敏感，包括低体积流量和快速波动。

This proposal is for the purchase of an electromagnetic flowmeter that will be used in conjunction with a particle imaging velocimetry (PIV) system and Doppler ultrasound (DUS) research system for various flow-related research studies. The PIV and DUS systems can be used to accurately and precisely map flow patterns and flow velocities with high spatial and temporal resolution for use in medical physics and soft condensed matter physics. The primary use of the flowmeter will be for measurements in physical models mimicking vascular flow, such as through arteries with plaque build-up, in order to gain a better understanding of hemodynamics (blood flow) changes due to disease progression. The flowmeter will be used to provide accurate in-line measurement and verification of the bulk flow rates and flow volume. These detailed flow studies require a flowmeter that does not disturb the flow being measured and is sensitive to pulsatile flow, including low volumetric flow rates and rapid fluctuations.
