摘要: Objectives: To integrate methods for non-invasive assessment of vessel wall properties (diastolic diameter, distension waveform and intima-media thickness) hemodynamic (blood flow velocity shear rate distribution) large arteries by means dedicated ultrasound signal processing. Methods: we have developed an arterial laboratory (ART-lab) system. ART-lab consists software running on a standard personal computer, equipped with data acquisition card the radio frequency (RF) signals obtained conventional echo scanner. It operates either (1) off-line or (2) in real-time. Real-time operation is restricted to because limitations computational power. Results: This paper provides overview RF-signal processing methods. The capabilities system are illustrated some typical applications. Conclusions: real-time mode useful tool monitoring dynamics, while it can be employed investigate elastic combination hemodynamics, such as blood distribution.
