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.

Common failures of color Doppler ultrasound

1. Control panel failure

2. System software, application software failure

3. Back end failure

4. Power failure (Main power supply, Low-voltage power supply, High-voltage power supply)

5. Transducer Probe failure

6. Front-end failure (Interface board, Transmitter, Receiver, Control, VIDEO, Front-end connection)

7. Display failure (Display, Workstation, Touch screen)

8. Failure caused by external environment

Front end troubleshooting summary

1. The front and back connection processing board has multiple functions

2. TR Board, image processing

3. Probe interface board failure

4. The back end board is responsible for the whole machine

5. The video board is responsible for image problems
