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 34.3 dB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。
Abstract
Sweep source optical coherence tomographic angiography (SS-OCTA) is a kind of angiography technol-ogies 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 C57BL6 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.
