The calibration method is able to eliminate the inconsistency of optoacoustic based temperature measurements caused by sample-to-sample and spatial variations of Gruneisen parameter for different tissues. The method for temperature-structure imaging is able to generate both two dimensional and three dimensional co-registered structure and temperature images for the tissues inside a region of interest of a subject.

摘要： Provided herein are scanning, high-resolution optoacoustic imaging systems or microscopes. Generally, the system/microscope comprises subsystems for scanning a tissue or object therein with a wavelength of electromagnetic energy, such as optical energy, collecting and detecting ultrasonic waves produced when the tissue or object absorbs the incident wavelength and converting the same to an electrical signal, and for processing, analyzing and displaying the electrical signal as a digital image. Specifically, the system/microscope utilizes an off-axis parabolic reflector with a high numerical aperture value for deep tissue visualization. Also, provided is a method for collecting volumetric image data voxel-by-voxel within a subject utilizing the imaging system or microscope. A series of voxels within the scanned tissue produces detectable ultrasonic waves that are collected by the off-axis parabolic reflector and processed as described as a high-resolution image of the tissue or object therein.

摘要： Provided herein are dual modality imaging systems and methods within displayed anatomical structures of placenta in real time. The imaging system comprises a dual modality laser optoacoustic and ultrasonic platform with a plurality of subsystems for delivering near infrared light, optoacoustic and ultrasonic pulses to the placenta and/or associated tissue and deep anatomic structures, for detecting ultrasonic pulses generated or reflected within the tissue using a multi-channel optoacoustic-ultrasound probe and associated transducers. The dual modality imaging system displays the results obtained as quantitative functional images of the parameters coregistered with anatomic tissue images. A multichannel electronic system comprising a computer tangibly storing software enables processor-executable instructions to calculate quantitative functional parameters of the placental blood within specific anatomical tissue structures and display quantitative functional optoacoustic images of the functional parameters within specific anatomical structures in the tissue that are visualized by ultrasound.
