Optical Coherence Tomography (OCT) provides a high-resolution imaging technique with limited depth
penetration. The current use of OCT is limited to relatively small areas of tissue for anatomical structure
diagnosis or minimally invasive guided surgery. In this study, we propose to image a large area of the
surface of the cerebral cortex. This experiment aims to evaluate the potential difficulties encountered
when applying OCT imaging to large and irregular surface areas. The current state-of-the-art OCT
imaging technology uses scanning systems with at most 3 degrees-of-freedom (DOF) to obtain a 3D
image representation of the sample tissue. We propose the use of a 7 DOF industrial robotic arm to
increase the scanning capabilities of our OCT. Such system will be capable of acquiring data from large
samples of tissue that are too irregular for conventional methods. Advantages and disadvantages of our
system are discussed.
