Stain-free Holographic Detection of Circulating Tumor Cells Using A Deep Feature Fusion Neural Network
2022 IEEE 4th International Conference on Artificial Intelligence Circuits and Systems (AICAS)(2022)
摘要
Circulating tumor cells (CTCs) have important reference value in cancer diagnostics. As the existing fluorescence-based CTC detection method faces the limitation of tedious staining steps and photobleaching, it's necessary to develop a stain-free identification method. This work demonstrated a stain-free holographic detection of CTCs using a deep feature fusion neural network. By utilizing the subtle difference between CTCs internal structures captured by the holographic microscope, the proposed neural network fuses low-level features extracted by the shallow layers with high-level features extracted by deep layers into fused features for CTCs identification, and reached an accuracy of 94%. Compared with the previous fluorescent stain-based method, this work provides a potential solution for high accuracy stain-free CTC detections.
