Abstract: 本发明公布了一种测量血管血液流量的设备和方法,包括:在光路上设置光源、分光模块、参考臂模块、样品臂模块、探测模块和控制系统;样品臂模块主要包括扫描单元和可旋转的光路平移装置;光源经分光模块后得到探测光,其主光线一直处于扫描单元的转动轴上;探测光经扫描单元扫描反射至光路平移装置,在光路平移装置分别处于第一位置及第二位置时,分别扫描眼底血管,得到被测血管的第一位相信号和第二位相信号,最后根据公式求得视盘附近单根血管的血液流速和流量,以及所有血管的血液流量。本设备和方法,避免了采集到的血管的原始多普勒图像出现的高频背景多普勒,省去了去除高频背景多普勒带来的额外工作和误差。

Abstract: Examples relate to a surgical microscope system, and to a system, a method and a computer program for a surgical microscope system. The system comprises one or more processors and one or more storage devices. The system is configured to obtain intraoperative sensor data of at least a portion of an eye from a Doppler-based imaging sensor of the surgical microscope system. The system is configured to process the intraoperative sensor data to determine infor- mation on a blood flow within the eye. The system is configured to generate a visualization of the blood flow. The system is configured to provide a display signal to a display device of the surgical microscope system based on the visualization of the blood flow within the eye.

Abstract: Systems and methods for performing a retinal angiogram, which can be used to non-invasively quantify retinal perfusion by measuring differences in retinal vascular density. The systems and methods can be used to measure a response of the vasculature, particularly in the choriocapillaris. The systems and methods can be used to diagnose neurodegenerative conditions, associated sleep and mood disorders, and measure metabolic reserve. In particular, the systems and methods can also be used for both diagnostics and prognostics.
