We demonstrate bio-medical imaging using a Terahertz quantum cascade laser. This new optoelectronic source of coherent Terahertz radiation allows building a compact imaging system with a large dynamic range and high spatial resolution. We obtain images of a rat brain section at 3.4 THz. Distinct regions of brain tissue rich in fat, proteins, and fluid-filled cavities are resolved showing the high contrast of Terahertz radiation for biological tissue. These results suggest that continuous-wave Terahertz imaging with a carefully chosen wavelength can provide valuable data on samples of biological origin; these data appear complementary to those obtained from white-light images.
我们展示了使用太赫兹量子级联激光器进行生物医学成像。这种新型的相干太赫兹辐射光电源能够构建一个具有大动态范围和高空间分辨率的紧凑型成像系统。我们获得了大鼠脑切片在3.4太赫兹频率下的图像。富含脂肪、蛋白质和充满液体的腔室的脑组织不同区域得以分辨，显示出太赫兹辐射对生物组织具有高对比度。这些结果表明，精心选择波长的连续波太赫兹成像能够为生物源样本提供有价值的数据；这些数据似乎与从白光图像中获得的数据互补。
