摘要
扫频源光学相干层析血管成像(SS-OCTA)是一种基于分频幅去相关血管造影法(SSADA)的新型血管成像技术,在肿瘤等疾病的早期诊断方面拥有较大前景。本文在5.12 mm×5.12 mm成像视场、标准图像最大信噪比34.3dB的SS-OCTA成像平台,对黑色素瘤C57BL6小鼠进行皮肤结构和血管成像采集。结果表明在皮肤科疾病的早期诊断方面,利用SS-OCTA系统进行血管成像优于结构成像。
Sweep source optical coherence tomographic angiography(SS-OCTA) is a kind of angiography technologies based on split spectrum amplitude deeorrelation angiography(SSADA). It has a great prospect in the early diagnosis of tumors and other diseases. In this paper, skin structure and angiography of melanoma C57 BL6 mice were collected on the basis of the SS-OCTA imaging platform with an imaging field of 5.12 mm×5.12 mm and a standard image maximum signal-to-noise ratio of 34.3 dB. The results show that the SS-OCTA system is superior to the structural imaging in early diagnosis of dermatological diseases.
