The key of ankle-brachial index (ABI) measurement is accurately measurement of upper and lower extremities systolic pressure. When the blood flow is blocked, blood flow will resume a normal beat and the corresponding cuff pressure of the first trough starting point is the systolic pressure. First it detects the pulse signal main frequency by spectral analysis of the pulse signal which based on ...

background: the interaction between the blood and the vessel wall is of great clinical interest in studying cardiovascular diseases, the major causes of death in developed countries. objective: to understand the effects of incorporating fluid-structure interaction into the simulation of blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from c...

Introduction Velocity encoded tine (VEC) MR imaging provides quantitative assessment of blood flow in the cardiovascular system. With use of segmented k-space fast VEC MR imaging, noninvasive assessment of blood flow and vasodilator flow reserve in the coronary artery and coronary arterial bypass graft can be obtained within a single breath-hold time. However, it has been pointed out that blood...

Previous studies have shown that the quantification of volumetric blood flow from a color Doppler image (CDI) is a feasible approach to eliminate technical obstacles in the traditional pulsed wave (PW) Doppler method. This paper introduces an automated method that computes the volumetric blood flow through a conduit while tracking the movement of blood flow. Correct calculation of the blood flo...
