Jugular venous pulse (JVP) indicates the right atrium pressure variations, which can be measured by the changes in the cross-sectional area of the IJV. Central venous line catheterization is the gold standard technique to assess the JVP. The invasive catheterization procedure might result in puncture of vessel walls resulting in deep vein thrombosis, and due to such associated risks, it is only limited to intensive care situations. Non-invasive JV diameter assessment is a preferable option for recording JVP and is commonly performed using ultrasound devices. The proposed A-mode ultrasound system relies on a single-element ultrasound transducer to transmit and receive A-mode radiofrequency (RF) echo signals from the Jugular vessel segment, operating in pulse-echo mode.  The 5 mm narrow-band transducer has a center frequency of 5 MHz and produces a focused beam. The 32-bit ARM cortex M4 (LPC4370FET256, NXP Semiconductors) microcontroller generates digital pulses to control the pulser-receiver and excites the transducer to transmit ultrasound pulses.
