Machine Learning Classification of Cervical Tissue Liquid Based Cytology Smear Images by Optomagnetic Imaging Spectroscopy

Le résumé fourni par la source

Semi-automated system for classification of cervical smear images based on Optomagnetic Imaging Spectroscopy (OMIS) and machine learning is proposed.Optomagnetic Imaging Spectroscopy has been applied to screen 700 cervical samples prepared according to Liquid Based Cytology (LBC) principles and to record spectra of the samples.Peak intensities and peak shift frequencies from the spectra have been used as features in classification models.Several machine learning algorithms have been tested and results of classification have been compared.Results suggest that the presented approach can be used to improve standard LBC screening tests for cervical cancer detection.Developed system enables detection of pre-cancerous and cancerous states with sensitivity of 79% and specificity of 83% along with AUC (ROC) of 88% and could be used as an improved alternative procedure for cervical cancer screening.Moreover, this can be achieved via portable apparatus and with immediately available results.
