Mindray DC-30

Hardware Principle 4-7
 The ECG signal, 2D image and color flow image are simultaneously displayed
on the system.
 After amplification, filtering and sampling, the ECG signal will be sent to DSP
board and R-wave detection is conducted at the same time.
 The detected ECG triggering signal will be sent to the DSP FPGA on the main
board through serial port.
