光和超声波的结合可以产生新的医学成像技术，将光的光谱能力与超声波的空间分辨率相结合。光谱学可用于测量血容量和血氧，但由于大多数生物组织在光学波长下高度散射，空间分辨率较差。超声波提供了出色的分辨率，但软组织对比度不佳。结合光和超声波的技术有很多，但本文讨论的两种技术在医疗应用中最有前景。第一种是光声成像，由激光脉冲产生声脉冲，并使用检测到的声音来生成图像。在第二种声光子成像中，超声波调制用于扩散光学断层扫描的激光。这两种技术都显示出在各种医疗应用中的前景。
The combination of light and ultrasound can lead to new medical imaging techniques combining the spectroscopic capability of light with the spatial resolution of ultrasound. Spectroscopy can be used to measure blood volume and blood oxygen, but because most biological tissues are highly scattering at optical wavelengths, spatial resolution is poor. Ultrasound provides excellent resolution, but not good soft-tissue contrast. There are many techniques for combining light and ultrasound, but the two discussed in this paper have emerged as having the most promise for medical applications. In the first, optoacoustic imaging, an acoustic pulse is generated by a pulse of laser light, and the detected sound is used to produce an image. In the second, acousto-photonic imaging, ultrasound modulates laser light used for diffusive optical tomography. Both of these techniques show promise for a variety of medical applications.
