    摘要： An imaging system is disclosed that includes a first imaging panel and a second imaging panel disposed about an imaging volume. The imaging panels may be configured to image the entire imaging volume and may include panels using any form of acoustic or electromagnetic energy such as ultrasound panels, optical panels, electrical impedance panels, field emitter/x-ray detector panels, or a combination thereof. In one embodiment, a first group of sensors are included in a 2D matrix of sensors configured to transmit ultrasound through the imaging volume to a second group of sensors included in a second 2D matrix of sensors and vice versa. In a second embodiment the system may further include a second imaging system having a transmitter, a receiver, or both, disposed adjacent the first imaging panel, the second imaging panel, or both. A third embodiment may include at least one additional imaging panel.

    摘要： In performing tissue-generated harmonic imaging using coded excitation, the transmit waveform for acquiring the N-th harmonic signal is biphase (1,−1) encoded using two code symbols of a code sequence, the portions (i.e., chips) of the transmit waveform encoded with the second code symbol each being phase-shifted by 180°/N relative to the chips encoded with the first code symbol. This is implemented by time shifting the portions (i.e., chips) of the transmit sequence which are encoded with the second code symbol by ½N fractional cycle at center frequency relative to the chips of the transmit sequence encoded with the first code symbol. During reception, the desired harmonic signal is isolated by a bandpass filter centered at twice the fundamental frequency and enhanced with decoding.
