1. An imaging system comprising:

  • a probe configured to transmit an ultrasound signal and a light signal into a tissue;

    a first ultrasound transducer configured to receive from the tissue an ultrasound response signal associated with the transmitted ultrasound signal;

    a second ultrasound transducer configured to receive from the tissue an optoacoustic response signal associated with the transmitted light signal;

    a first amplifier configured to receive the ultrasound response signal from the first ultrasound transducer, wherein an input impedance of the first amplifier is determined by a first bandwidth associated with the ultrasound response signal; and

    a second amplifier configured to receive the optoacoustic response signal from the second ultrasound transducer, wherein an input impedance of the second amplifier is determined by a second bandwidth associated with the optoacoustic response signal;

    wherein the first bandwidth is narrower than the second bandwidth.
