Article Synopsis
- Cutaneous blood flow is crucial for understanding skin diseases like basal cell carcinoma (BCC), allowing for better diagnosis and treatment.
- An automated algorithm is introduced that uses optical coherence tomography angiography (OCTA) images to determine the skin lesion area by segmenting and analyzing blood vessels.
- Tests on various types of BCC show that this method delivers precise, non-invasive, and quantitative results, improving lesion area determination compared to traditional methods.
Article Synopsis
- A forward imaging endoscope has been developed for optical coherence tomography angiography (OCTA) using a piezoelectric fiber scanner, featuring an optical coherence tomography (OCT) system with a specific wavelength and rate.
- The endoscope, designed to operate in contact mode to reduce motion artifacts, achieves high resolution and a significant field of view while utilizing a spiral scan pattern.
- This technology allows for detailed imaging of human tissues and blood flow, which could enhance early diagnosis of diseases like bladder cancer.
Imaging of the human retina with high resolution is an essential step towards improved diagnosis and treatment control. In this paper, we introduce a compact, clinically user-friendly instrument based on swept source optical coherence tomography (SS-OCT). A key feature of the system is the realization of two different operation modes.

We demonstrate noninvasive structural and microvascular contrast imaging of human skin in vivo, using phase difference swept source OCT angiography (pOCTA). The pOCTA system employs an akinetic, all-semiconductor, highly phase-stable swept laser source which operates at 1340 nm central wavelength, with 37 nm bandwidth (at 0 dB region) and 200 kHz A-scan rate. The phase sensitive detection does not need any external phase stabilizing implementations, due to the outstanding high phase linearity and sweep phase repeatability within 2 mrad.
