Abstract

The current invention concerns a method for detecting cancerous cells and/or classifying cells in a cell sample comprising the following steps: providing a cell sample; obtaining holographic information from said cell sample by digital holographic microscopy (DHM); deriving at least one cellular parameter from said holographic information, and; classifying said cells of cells sample; characterized in that said classification occurs by appointing a Scoring Factor to said cells of cell sample, based on said cellular parameters. In a second aspect, a system for the detection of cancerous cells and/or classification of cells in a cell sample is provided, employing the method as disclosed in the invention. In a final aspect, a method for updating and/or improving a database comprising thresholds linked to holographic information and the database related thereof is equally disclosed.

Claims (48)

4. A method according to claim 1 , wherein image identification, comprising an identification tag or code uniquely linked to an obtained image and/or to objects in the image, is linked to said cellular parameters and Scoring Factor derived thereof.

5. A method according to claim 1 , wherein said appointed Scoring Factor is based upon comparison of said at least one cellular parameter and a threshold database.

6. A method according to claim 5 , wherein said threshold database is stored on an internal or external server.
