Abstract
Systems, methods, and devices for directed to duplex imaging techniques for combining high-resolution surface images obtained with a Scanning Fiber Endoscope (SFE), and high-resolution penetrating OCT images obtained through Optical Coherence Tomography (OCT), from a SFE, and interleaving frames to improve resolution and identify below surface information of biological structures.
Claims17
A method for acquiring OCT B-mode images, comprising:
- oscillating a cantilever scanning fiber within a probe along a scanning path, wherein the probe is configured to obtain reflected light generated by the scanning fiber, and the oscillating scanning path increases in amplitude over time;
- obtaining a plurality of A-line scans from the obtained reflected light, each A-line scan obtained at a point along the oscillating scanning path that the scanning fiber reaches a minimum speed;
- and
- constructing a B-mode image from the plurality of A-line scans.
1 more element
A non-transitory computer readable storage medium comprising instructions stored thereon that cause a computing system to at least:
- oscillate a cantilever scanning fiber within a probe along a scanning path, wherein the probe is configured to obtain reflected light generated by the scanning fiber, the oscillating scanning path increasing in amplitude over time;
- obtain a plurality of A-line scans from the obtained reflected light, each A-line scan obtained at a point along the oscillating scanning path where a speed of the scanning fiber is at a minimum;
- and
- construct a B-mode image from the plurality of A-line scans.
