Optical projection imaging system and method for automatically detecting cells with molecular marker compartmentalization associated with disease

摘要

A system and method for rapidly detecting cells associated with malignancy and disease using molecular marker compartmentalization includes an optical tomography (OT) or a flow optical tomography (FOT) instrument capable of producing various optical projection images (or shadowgrams) containing accurate density information from a cell or cells labeled with tagged molecular probes or stains, a computer and software to analyze and reconstruct the projection images into a multi-dimensional data set, and automated feature collection and object classifiers. The system and method are particularly useful in the early detection of cancers such as lung cancer using cells from sputum or cheek scrapings and cervical/ovarian cancer using a cervical scraping, and the system can be used to detect rare cells in specimens including blood.
