Knowledge Point
Color Doppler flow imaging
Color Doppler flow imaging system can simultaneously display B-type
image and Doppler blood flow data (blood flow direction, flow
velocity, flow dispersion) of dual ultrasound scanning system.
Color power angio(CPA) detected the backscattered energy of blood
cells in the blood flow, which did not distinguish the flow
direction, and had nothing to do with the angle θ (the angle
between the direction of sound wave and the direction of blood
flow). CPA can improve the sensitivity of blood flow detection,
especially suitable for displaying low-speed blood flow of small
vessels, but can not show the direction of blood flow.
Harmonic imaging
Harmonic imaging exploits non-linear propagation of ultrasound
through the body tissues. When the frequency of emitted sound wave
is f 0, the frequency of echo (due to reflection or scattering)
includes f 0 (called fundamental wave), 2f 0, 3F 0 and so on The
second harmonic (2f 0) has the largest energy.
Ultrasonic harmonic imaging (UHI) is based on the information of
human body carried by the second harmonic in echo (reflection or
scattering). Harmonic imaging without UCA is called native harmonic
imaging or tissue harmonic imaging. Harmonic imaging using UCA
(ultrasound contrast agent) is called contrast harmonic imaging.
Daily and Long-Term Storage of ultrasound transducer
1. Always store transducers in the transducer holders on the side
of your system or on a securely mounted wall rack when you are not
using them.
2. Ensure the transducer holders are clean before storing
transducers
3. When storing transducers, use the cable-management clips, if
available, to secure the transducer cable
4. Avoid storing transducers in areas of temperature extremes or in
direct sunlight.
5. Store transducers separately from other instruments to avoid
inadvertent transducer damage.
6. Before storing transducers, make sure they are thoroughly dry.
