我们展示了生物医学成像使用太赫兹量子级联激光器。这种新的相干太赫兹辐射的光电源允许构建具有大动态范围和高空间分辨率的紧凑型成像系统。我们在3.4 THz下获得了大鼠大脑切片的图像。富含脂肪、蛋白质和充满液体的空腔的脑组织的不同区域被分辨出来，显示出生物组织的太赫兹辐射的高对比度。这些结果表明，连续波太赫兹成像与精心选择的波长可以提供有价值的数据，生物来源的样本，这些数据出现互补的白光图像。(C)2004年美国光学学会。
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.
