1. A modularized acoustic probe comprising:
a probe scanhead including:
an acoustic transducer disposed on a first substrate and configured to generate an acoustic signal and to transmit the acoustic signal toward tissue or bone;
an optical sensor disposed on a second substrate and configured to detect a reflected acoustic signal, which results from the acoustic signal reflecting from the tissue or bone and to convert the reflected acoustic signal to an electrical signal, wherein the first substrate of the acoustic transducer and the second substrate of the optical sensor are discrete substrates and wherein the acoustic transducer and the optical sensor have at least one different acoustic parameter;
a thermal module disposed on the second substrate including at least one thermal circuit and configured to regulate a temperature inside the probe scanhead;
a first lens module associated with the acoustic transducer and configured to provide mechanical focusing of acoustic signals transmitted by the acoustic transducer; and
a second lens module associated with the optical sensor having a different acoustic design than the first lens module and configured to provide mechanical focusing of acoustic signals received by the optical sensor.
