Abstract

The optical properties of different cow and pig biological tissues such as skeletal muscle, adipose, spinal cord, and dura mater of the spinal cord were investigated in the spectral range of 350 to 2600 nm. The measurements were carried out by a commercially available spectrophotometer SHIMADZU UV 3101PC. The wavelength dependence on the scattering coefficient has been observed to follow a power-law decay for skeletal muscle and dura mater of spinal cord. The influence of time delay between the sample preparation and measuring of transmittance spectra on the data reasonableness was reviewed. The conclusion about the benefits of 2 - ? m lasers application in surgery is given for the tissue types listed above.

摘要

研究了牛和猪的不同生物组织（如骨骼肌、脂肪、脊髓和硬脑膜）的光学特性，光谱范围为 350 至 2600nm。测量是通过市售分光光度计 SHIMADZU UV 3101PC 进行的。观察到散射系数随波长的变化遵循幂律衰减，适用于骨骼肌和脊髓硬脑膜。还回顾了在测量透过率光谱之前和之后，组织制备时间延迟对数据合理性的影响。针对上述组织类型，给出了在手术中应用 2μm 激光的好处的结论。
