A method and system for imaging a sample uses a 2D array of bias-sensitive, ultrasound transducers arranged in first and second strips, and a source of radiation to stimulate the sample to be imaged. The second electrode strips are sequentially biased according to sequential biasing patterns of voltages that correspond to rows or columns of an invertible matrix. For each biasing pattern, signals are measured from the first electrode strips to detect return signals from the sample that result from the sample being stimulated. A dataset is calculated based on the measured signals, the dataset comprising an effective signal for each of a plurality of transducer elements in the array. An image of the sample is generated based on the dataset.

This invention provides a signal-processing method that makes it possible to acquire, relatively easily and surely, a highly reliable normalized impulse-response signal without relying on the signal-correction processing after normalization. The signal-processing method of this invention includes a low-frequency extraction step, a high-frequency extraction step and a synthesizing step. In the low-frequency extraction step, only the low-frequency component is extracted from the spectrum of the first normalized signal NS1 obtained by normalizing the target signal S.sub.tgt in the time domain. In the high-frequency extraction step, only the high-frequency component is extracted from the spectrum of the second normalized signal NS2 obtained by normalizing the target signal S.sub.tgt in the frequency domain using the reference signal S.sub.ref. In the synthesizing step, the low-frequency component, derived from the first normalized signal NS1, and the high-frequency component, derived from the second normalized signal NS2, are synthesized to obtain a normalized impulse-response signal NS.
