    Abstract: A method for automated detection, monitoring and treatment of dysplasia by analyzing 3D reconstructed images of cells obtained from a specimen includes a biological specimen classifier that classifies cells from the sputum specimen as normal or abnormal. If abnormal cells are detected, then the abnormal cells are further classified as pre-cancerous or cancerous. Pre-cancerous cells are further sub-classified as being of glandular origin or squamous origin (dysplastic cells). This information would be used to define patient therapy so that if the cells are classified as dysplastic, then a cancer chemoprevention pharmaceutical like iloprost is administered to the subject over a predetermined time period to achieve a therapeutic dosage, and if only malignant cells were found or malignant and pre-cancerous cells were found, then next steps would involve patient triage to biopsy and surgery and possibly use of a cancer chemoprevention pharmaceutical.

    Abstract: A method for 3D imaging of a biologic object (1 ) in an optical tomography system where a subcellular structure of a biological object (1 ) is labeled by introducing at least one nanoparticle-biomarker. The labeled biological object (1 ) is moved relatively to a microscope objective (62) to present varying angles of view and the labeled biological object (1 ) is illuminated with radiation having wavelengths between 150 nm and 900 nm. Radiation transmitted through the labeled biological object (1 ) and the microscope objective (62) within at least one wavelength bands is sensed with a color camera, or with a set of at least four monochrome cameras. A plurality of cross-sectional images of the biological object (1 ) from the sensed radiation is formed and reconstructed to make a 3D image of the labeled biological object (1 ).

    Abstract: A method for tracking an object (414) in a system for optical tomography, where the object (414) is contained in a tube (410) having a center of rotation (422), the object (414) has a centroid (415), and the object (414) is offset from the center of rotation. Image data is acquired by scanning the object (414) through an extended depth of field while the object (414) is being rotated. A distance value of the object (414) centroid (415) from the center of rotation is calculated from the image data, A rotation angle value (.beta.R) is caicuiated from the acquired image data. An extent of the object (414) is determined limiting the extended depth of field being scanned to less than or equal to the extent of the object (414) so as to increase image resolution in a resultant pseudoprojection image.

    Abstract: A cytological analysis test for 3D cell classification from a specimen. The method includes isolating and preserving cells from the specimen and enriching the cells before embedding the enriched cells into an optical medium. The embedded cells are injected into a capillary tube where pressure is applied until a 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.

    Abstract: The present disclosure provides a system and method for AI-based cell classification of cells from a patient sample to determine if cells indicative of lung cancer are present. In the system and method, 2D imaging is used to eliminate cells not likely to be indicative of lung cancer from subsequent 3D imaging, while 3D imaging is conducted for cells likely to be indicative of lung cancer. The present disclosure further provides a method of training 2D cell classifiers for use in the system and method for AI-based cell classification.
