Embodiments of the present disclosure are directed to a vessel-wall-monitoring device () and a method for identifying the walls of blood vessel in a body. The method includes receiving, by the vessel-wall-monitoring device (), a plurality of ultrasound echo signals from a transducer, wherein the plurality of ultrasound echo signals are transmitted to the transducer from locations of the blood vessel, extracting at least two consecutive ultrasound frames from the plurality of ultrasound echo signals, determining a shift between the at least two consecutive ultrasound frames by comparing samples of the at least two consecutive ultrasound frames, and identifying, a proximal wall and a distal wall of the blood vessel based on the shift between the at least two consecutive ultrasound frames.

Methods for identifying the boundaries of a blood vessel

Embodiments of the present disclosure are directed to an vascular-dynamics-monitoring device () and methods for tracing a motion of boundaries of a vessel in a human body. The method features an automated gating of vessel walls' echoes in an ultrasound frame input to the vessel, accurate shift estimation for the gated vessel wall region, despite the presence of echoes from moving structures adjacent to the vessel and real-time trace of vessel walls' boundaries.
