20. A method for optoacoustic imaging a structural or compositional characteristic of an object, the method comprising:
-
generating an electromagnetic radiation excitation signal;
controlling characteristics of the excitation signal using a pulse shaper;
generating acoustic waves in an object by directing the dynamically controlled excitation signal at the biological object and irradiating the biological object;
detecting the generated acoustic waves from the object using at least one acoustic receiver; and
determining a structural or compositional characteristic of the object by processing the detected acoustic wave signal. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
