Optical coherence tomography (OCT)

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.)
