In the field of medical image diagnosis, ultrasound imaging is a common diagnostic method. The ultrasonic imaging is based on the mechanical property of the detected biological tissue, the imaging contrast is low, and meanwhile, the traditional ultrasonic imaging depends on the acoustic impedance change of the biological tissue, and only interface reflection imaging can be realized, and chromatographic imaging cannot be realized.
While the advantage of optical methods lies in its functionality and sensitivity, currently, the interaction of light with tissue is mainly due to both absorption and scattering: wherein the optical absorption property of the tissue is related to the tissue components, and the component change of the tissue can reflect the change of the biochemical state of the tissue body, so that the biochemical state of the tissue body can be judged according to the optical absorption property; light scattering in biological tissues results from random variations in refractive index at the micrometer scale, while the physiological basis for fluctuations in refractive index at the micrometer scale is the variation of biological tissues from one another at the cellular and subcellular levels, so it is believed that changes in morphology of tissue bodies at the cellular and subcellular levels can be inferred from optical scattering properties. In summary, the optical properties of the tissue volume (scattering and absorption) have the ability to assess the biochemical and morphological state of the focal tissue. In addition, the optical properties are sensitive to the above changes occurring in the tissue, which makes it possible to have high image contrast in optical imaging. Therefore, the characteristics of the functionality and the sensitivity of the optical technology can be utilized to quantitatively evaluate the functions of the tissues.
However, light irradiation of biological tissue exhibits strong scattering properties, typically with a scattering coefficient of about 100cm-1, which makes optical imaging impossible with both resolution and imaging depth.
Unlike light propagating in tissue, which exhibits strong scattering, ultrasound scatters 2-3 orders of magnitude less in tissue than light, meaning that ultrasound imaging techniques can somehow be compatible in terms of resolution and imaging depth. However, the source of the graph contrast of the ultrasonic imaging technology is the difference of biological tissues in mechanical properties, the imaging contrast is low, and the ultrasound depends on the acoustic impedance change of the tissues, can only realize interface reflection imaging, cannot realize tomography, is not suitable for the examination of gas-containing organs (such as lung, digestive tract and bones), and also limits the ultrasonic imaging technology in the aspect of early cancer diagnosis; in addition, ultrasound technology does not have the ability to assess tissue body function.
