1. A laser ultrasonic imaging system, comprising:

  • a) means for delivering short pulses of optical energy to an array of ultrasonic emitters comprising optically absorbing elements placed in specific locations configured for efficient conversion of the absorbed optical energy into a short pulses of acoustic energy within a wide band of ultrasonic frequencies;

    b) means for delivering said short ultrasonic pulses with known amplitude and ultrasonic frequency spectrum through a coupling medium to a volume of interest in a subject at a given time or time zero;

    c) means for detecting said ultrasonic pulses in multiple positions at or around said volume of interest and measuring one or more parameters of time of propagation, amplitude and ultrasonic frequency spectrum, after said ultrasonic pulses are transmitted through or reflected from the volume of interest using an array of wide-band ultrasonic transducers that convert ultrasonic pulses into electronic signals;

    d) means for analog amplification and digital recording of said electronic signals;

    e) means for performing signal processing to remove distortions of electronic signals;

    f) means for image reconstruction using mathematical tomography algorithms;

    g) means for image processing and display;

    h) means for data transmission and system control.
