Abstract
Provided herein are the systems, methods, components for a three-dimensional tomography system. The system is a dual-modality imaging system that incorporates a laser ultrasonic system and a laser optoacoustic system. The dual-modality imaging system generates tomographic images of a volume of interest in a subject body based on speed of sound, ultrasound attenuation and/or ultrasound backscattering and for generating optoacoustic tomographic images of distribution of the optical absorption coefficient in the subject body based on absorbed optical energy density or various quantitative parameters derivable therefrom. Also provided is a method for increasing contrast, resolution and accuracy of quantitative information obtained within a subject utilizing the dual-modality imaging system. The method comprises producing an image of an outline boundary of a volume of interest and generating spatially or temporally coregistered images based on speed of sound and/or ultrasonic attenuation and on absorbed optical energy within the outlined volume.
