Previously we had shown that high-throughput label-free cell classification with high accuracy can be achieved through a combination of time-stretch microscopy, image processing and feature extraction, followed by deep learning for finding cancer cells in the blood. UCLA is an Equal Opportunity/Affirmative Action employer. Label-free imaging is implemented by quantitative phase imaging 32, 33 and the trade-off between sensitivity and speed is mitigated by using amplified time-stretch dispersive Fourier transform 34, 35, 36, 37, 38, 39, 40, 41.
