利用光声相关谱法对血液流速进行了测量，并研究了激光重复频率以及血流方向与入射激光传播方向的夹角对血液流速测量准确性的影响。结果表明：血流速度越快，要求激光的重复频率越高；当血流方向与入射激光的传播方向垂直时，系统可以测量的血液流速范围为0.059～92.3 mm/s，测量值与真实值的相关系数为0.992；当血流方向与入射激光的传播方向不垂直时，测得的血液流速和实际血液流速的比值与样品倾斜角度成余弦关系。

Photoacoustic tomography (PAT) is an emerging biomedical imaging modality that combines the high-contrast and spectroscopic-based specificity of optical imaging with the high spatial resolution of ultrasound imaging in a single modality. By listening to light, PAT detects tissue-absorbed photons ultrasonically through the photoacoustic effect. Since ultrasonic scattering is two to three orders of magnitude weaker than optical scattering in tissue, PAT breaks the 2–4 mm spatial resolution limit associated with pure optical tomography such as diffuse optical tomography (DOT) for deep tissue imaging, or the ~1 mm depth limit associated with confocal and multiphoton microscopy and optical coherent tomography (OCT). In PAT, tissue is excited with a short (typically a few nanoseconds) laser pulse (focused or unfocused); the subsequent laser-induced transient photoacoustic waves in the range of 1–100 MHz, due to the transient thermoelastic expansion of light-absorbing components in tissue, are detected by wideband unfocused or focused ultrasound transducer(s). Unique advantages of PAT are that functional or biochemical parameters such as deoxy-hemoglobin (HbR), oxy-hemoglobin (HbO2), water (H2O), lipids, and so forth along with vasculature and blood flow can be imaged in high resolution. In addition, highly specific molecular PAT can be realized through the use of molecular contrast agents. Finally, PAT can be made portable for bedside applications, is economical, and uses non-ionization radiation.
