Abstract: A cell classification system includes an optical tomography system and a processor operable to generate a plurality of 2D images and a plurality of pseudo-projection images of a cell. The processor executes instructions that cause the processor to: generate a 3D image of the cell using the pseudo-projection images; apply digital enhancement to a 2D or 3D image to improve determination of boundaries of structures with the cell that provide indicia of cell features; analyze at least one of the cell features or 2D or 3D images using AI-based cell characterization to characterize the cell as normal or as having abnormal features by analyzing the boundaries of structures; create a Normal Cell Gallery comprising images characterized by AI-based characterization as normal; create a Diagnostic Cell Gallery with images characterized by AI-based characterization as having abnormal features; display at least the Diagnostic Cell Gallery; and record a user classification.

Abstract: A cytological analysis test for 3D cell classification from a specimen. The method includes isolating and preserving a cell from the specimen and enriching the cell before embedding the enriched cell into an optical medium. The embedded cell is injected into a capillary tube where pressure is applied until the cell appears in a field of view of a pseudo-projection viewing subsystem to acquire a pseudo-projection image. The capillary tube rotates about a tube axis to provide a set of pseudo-projection images for each embedded cell which are reconstructed to produce a set of 3D cell reconstructions. Reference cells are classified and enumerated and a second cell classifier detects target cells. An adequacy classifier compares the number of reference cells against a threshold value of enumerated reference cells to determine specimen adequacy.
