A dynamic impedance imaging system includes a dynamic impedance imaging sensor, an impedance detection and flow rate measurement module and an electrical impedance tomography (EIT) instrument. The impedance detection and flow rate measurement module is configured to detect an abnormal particle flowing through the dynamic impedance imaging sensor to obtain a flow rate of the abnormal particle, and generate a synchronous trigger signal. The EIT instrument is configured to inject a sinusoidal excitation current into the dynamic impedance imaging sensor under the trigger of the synchronous trigger signal, perform multi-channel interleaved sampling for the abnormal particle according to the flow rate to acquire multi-channel sampled data, and calibrate the multi-channel sampled data to implement impedance tomography imaging for the abnormal particle.
