Abstract

In an imaging device having an objective and a stage for holding a sample to be imaged, a method for autofocusing is presented. The method includes determining a measured focus value corresponding to at least a first of a plurality of logical image segments. Further, the method includes imaging the first logical image segment using the measured focus value. The method also includes determining a predicted focus value for a second of the plurality of logical image segments using the measured focus value and a stored focus variation parameter. In addition, the method includes imaging the second logical image segment using the predicted focus value.

Description

[0001] Cross-reference to related applications [0002] This application is a continuation of US Patent Application No. 11 / 843,754, filed August 23, 2007, entitled "PREDICTIVE AUTOFOCUSING", which is incorporated herein by reference. technical field [0003] Embodiments of the present invention relate to imaging, and more particularly, to predictive autofocusing of imaging devices. Background technique [0004] Prevention, monitoring, and management of physiological conditions such as cancer, infectious diseases, and other disorders require timely diagnosis of these physiological conditions. Typically, biological samples from patients are used for analysis and identification of diseases. Microscopic analysis is a widely used technique in analyzing and evaluating these samples. More particularly, the sampling can be studied to detect the presence of abnormal numbers or types of cells and / or tissues that can be indicative of a disease state. Automated microscopy analysis sy...
