Vascular Dopplers and Foetal Dopplers
Both ultrasound machines touch on the principle of Doppler sonography with which frequency changes from sound waves generated by structural movements are made 'visible' i.e. blood flow or foetal heart activity. As a non-invasive and innocuous procedure, sonography is crucial for angiology and gynaecology diagnostics.
Vascular Dopplers for Examination of Veins
Vascular Dopplers are used for angiological examinations to diagnose vascular diseases in a non-invasive manner. This includes varicose veins, venous thrombosis and reflux caused by insufficient venous valves.
The Doppler ultrasound presents the blood flow speed in an examined vein both optically and acoustically. Vascular constriction and vascular occlusions are quite reliably determined.
Some alternative procedures in sonography include two-dimensional ultrasound procedures, compression ultrasound, duplex ultrasound and colour duplex ultrasound.
The Different Devices
Generally, one differentiates between the CW Doppler (continuous wave Doppler) and the PW Doppler (pulsed wave Doppler). CW Dopplers can be used to precisely measure and display high flow velocities, as their probe transmits and receives continuously. As a result, they are often used in cardiology.
For preciser results in the ultrasound depth, we recommend the use of a PW Doppler. The probe sends out high frequency pulses instead of one continuous signal. Additionally, the reflecting signal is only received in a very short time frame. With its help, the medical professional determines the size and localisation of the examined area.
In addition, this category also offers CTG devices to monitor baby movement, foetal heartbeat and labour in pregnant women.
Foetal Dopplers to Monitor the Heartbeats of an Unborn Child
Foetal Dopplers are important diagnostic devices in gynaecology and obstetrics. They allow for the monitoring of foetal heartbeats within the womb during pregnancy. We offer you handy and mobile foetal Dopplers, as well as foetal heart monitors with colour display and printers for stationary use.
The medical devices are equipped with high-quality speakers, and many can also be used with headphones, to allow the doctor or midwife to listen to even the smallest sounds.
Ultrasound Beam Angle
The Doppler frequency depends on the beam angle. If the angle is as steep as possible, the number of erythrocytes detected by the sound wave is increased. This leads to an increased intensity of the Doppler signal and a low diffusion.
As a result, the greatest Doppler effect occurs at 90° while there is no Doppler effect at 0°.
