Optical coherence tomography (OCT) is a fundamentally new type of optical imaging modality. ¢ OCT performs high-resolution, cross-sectional tomographic imaging of the internal microstructure in materials and biologic systems by measuring backscattered or backreflected light.

 

ADVANTAGES OF OCT

• Broad dynamic range

• High resolution

• Rapid data acquisition rate

• Small inexpensive catheter/endoscope design

• Compact portable structure (fiber optically based, making possible the development of small catheters and endoscopes)

• The frame rate for OCT systems are four to eight frames per second.(assume an image size of 256 by 512 pixels.)
