Researchers from Duke University have developed a way to use optical coherence tomography (OCT) in hard-to-reach areas of the body such as joints. The method may allow the technique to see use in further surgical and medical applications.
The researchers used a rigid borescope, essentially a thin tube of lenses, to deliver the infrared light necessary to perform OCT. Measuring just 4 mm in diameter, the borescope makes the beam delivery portion of the device very slim without sacrificing imaging performance.
Researchers used a new endoscopic OCT system to visualize variances in pig cartilage thickness. The image shows a sketch of a femur and processed OCT images with thin regions shown in dark red and thicker regions more yellow…
