The Doppler Sonography (Scientech 13E) is used to measure the blood flow with the doppler ultrasound. A realistic arm model is used to show the differences between continuous (venous) and (arterial) flow and between normal blood flow and stenosis.
Doppler sonography is an ultrasound-based technique used to study the movement of blood through blood vessels. Understanding what is Doppler sonography helps students learn how ultrasound and the Doppler effect can be used to assess blood flow and its direction. This makes Doppler sonography an important topic for understanding ultrasound-based blood flow measurement.
Doppler Sonography
Doppler Sonography uses the doppler effect to assess whether structures (usually blood) are moving towards or away from the ultrasonic probe,and its relative velocity. By calculating the frequency shift of a particular sample volume, for example a jet of blood flow over a heart valve, speed and direction of sample volume can be determined and visualised. Doppler frequency shift is the difference in ultrasound frequency between transmitted and received echoes, the echoes frequency minus the transmitted frequency. The doppler frequency is proportional to the blood flow velocity. Doppler sonography is used for cardiovascular studies, including sonography of the vascular system and heart, as well as for assessing blood flow in the liver.
The sonography Doppler technique allows learners to understand how frequency shifts can be used to study blood flow. In simple terms, Doppler sonography means using the Doppler effect in ultrasound to assess the movement and velocity of blood or other moving structures.
The Scientech 13E provides practical exposure to Doppler sonography principles and helps learners understand how sonography Doppler techniques can be used to study blood flow patterns. It also provides a practical way to understand what is Doppler sonography through an arm model and controlled blood flow simulation.
Procedure
The pump is switched on and the speed is adjusted in a middle range (ca. 4000 min -1). The mode is GK (continuously, venous). With the doppler probe and coupling gel the arm model is scanned for a vessel with a significant audio signal. The flow in the spectral image is analysed for negative and positive components . The probe direction is then switched by 180º. Then the vessel is scanned for changes in the spectral image and the differences between the image of a healthy vessel and the stenosis will be characterized. The pump is switched to P1 and P2 modes (pulsatile), and the resulting images are analysed to determine the pulse rate.
The procedure provides hands-on learning of Doppler sonography and demonstrates how changes in blood flow can be observed using the Doppler ultrasound technique. Through this procedure, learners can gain a clearer understanding of sonography Doppler principles and how Doppler sonography means assessing blood movement using ultrasound-based Doppler measurements.
