Convolutional neural network (CNN) based needle-tracking for OCT-guided cornea “Big Bubble” procedure (Conference Presentation)

Paper Abstract

In a partial cornea transplant surgery, a procedure known as “Big Bubble” is used and it requires precise needle detection and tracking. To accomplish this goal, we used traditional image segmentation methods and trained a Convolutional Neural network (CNN) model to track the needle during the cornea transplant surgery guided by OCT B-scan imaging. The dataset was generated from the laboratory OCT system and we classified them to three categories. The network architecture is based on U-Net and modified to avoid overfitting. We are able to track the needle and detect the distance between the needle tip and cornea bottom layer based on these results.
