Working Principle

The U20C operates by transmitting high-frequency ultrasound waves into the body through an electronic convex array probe and receiving echoes reflected by internal tissues and organs. The system processes these echo signals to reconstruct ultrasound images for clinical interpretation.

Its digital beamforming (DBF) technology coordinates signals from multiple probe elements. Real-time dynamic aperture imaging and dynamic transmit and receive focusing optimize signal acquisition across different imaging depths. Dynamic frequency scanning and eight-segment digital time-gain compensation (TGC) help adjust image acquisition and compensate for differences in echo intensity.

The processed signals undergo digital filtering, grayscale conversion, image enhancement, and other image processing operations before being displayed. Depending on the selected mode, the system presents two-dimensional B-mode images, combined B-mode views, four-panel images, or motion-related M-mode displays.

Measurement tools and cine-loop playback support further examination and review. Digital storage, USB transfer, and DICOM communication facilitate image documentation and integration with compatible medical information workflows.
