How does Optical Coherence Tomography reduce motion artifacts?
Aug 08 , 2025
1.Improvements at the hardware level (1) Increase the scanning speed Frequency domain OCT (FD-OCT) : Compared with time domain OCT (TD-OCT), FD-OCT has A faster scanning speed (up to tens of thousands to hundreds of thousands of A-scans per second), significantly reducing artifacts caused by patients' minor movements (such as eye tremors and breathing). Swept-frequency OCT (SS-OCT) : By rapidly tu...

1. Patients with difficulty in venipuncture Typical population Obese people (with thick subcutaneous fat layers and deeply hidden veins). Infants and children (with thin blood vessels and low cooperation). The elderly (with poor vascular elasticity and prone to rolling). Patients who have received long-term intravenous infusion or chemotherapy (with hardened blood vessels and many scars). Scene va...

I. What is OCT? A Core Metaphor Let's understand OCT through a vivid analogy: Imagine a fresh sandwich. A regular camera can only capture its top view (a two-dimensional photo). OCT, however, acts like a precise “optical scalpel.” It can slice the sandwich layer by layer without damage, capturing ultra-high-resolution images of each component (bread, vegetables, meat slices). These cross-sectional...

Early detection of diabetic retinopathy using OCT imaging
Jan 22 , 2026
1) Traditional Screening Methods and Their Limitations Traditionally, the screening and staging of DR Mainly relied on color fundus photography to observe two-dimensional surface lesions such as retinal microaneurysms, hemorrhage and exudation. However, this method has limitations: Strong subjectivity: Relying on the doctor's experience. Inability to observe deep structures: It is impossible to qu...
