Knowledge Point
**Color Doppler Flow Imaging:**
The Color Doppler flow imaging system is designed to simultaneously present B-type images and Doppler blood flow data, revealing information about blood flow direction, velocity, and dispersion. The dual ultrasound scanning system is instrumental in this process. The Color Power Angio (CPA) component detects the backscattered energy of blood cells without distinguishing the flow direction, independent of the angle θ (the angle between the direction of the sound wave and the blood flow direction). While CPA enhances the sensitivity of blood flow detection, especially for low-speed blood flow in small vessels, it does not provide information about the direction of blood flow.
**Harmonic Imaging:**
Harmonic imaging capitalizes on the non-linear propagation of ultrasound through body tissues. By emitting sound waves at a frequency of f0, the resulting echo frequencies include f0 (fundamental wave), 2f0, 3f0, and so forth. The second harmonic (2f0) holds the highest energy. Ultrasonic Harmonic Imaging (UHI) relies on the information carried by the second harmonic in echoes, with or without the use of Ultrasound Contrast Agents (UCAs). Harmonic imaging without UCAs is termed native harmonic imaging or tissue harmonic imaging, while the use of UCAs is referred to as contrast harmonic imaging.
**Daily and Long-Term Storage of Ultrasound Transducers:**
1. Transducers should be stored in the designated holders on the ultrasound system or a securely mounted wall rack when not in use.
2. Ensure that the transducer holders are clean before storing transducers.
3. When storing transducers, use cable-management clips, if available, to secure the transducer cable.
4. Avoid storing transducers in areas with extreme temperatures or direct sunlight.
5. Transducers should be stored separately from other instruments to prevent inadvertent damage.
6. Before storing, ensure that transducers are thoroughly dry.
