激光多普勒测速器(LDV)是应用氮氖激光照射于移动的红细胞在反射光谱中产生的多普勒频移,以测定血流速度和流量。基底细胞癌血管系统增加,病灶内的血流比正常皮肤相应增多。作者应用 LDV 测量肿瘤与正常皮肤的血流量以测定基底细胞癌的边界大小并与临床观察和经 Mohs
Laser Doppler Velocimetry (LDV) is a Doppler shift in the reflectance spectrum of a moving red blood cell using a Nd laser to determine blood flow velocity and flow. The vascular system of basal cell carcinoma increases, and the blood flow within the lesion increases correspondingly compared with normal skin. The authors used LDV to measure the blood flow between tumors and normal skin to determine the boundary size of basal cell carcinoma and to observe with the clinical and Mohs.
