Abstract

A system and method for image-guided microscopic illumination are provided. A processing module controls an imaging assembly such that a camera acquires an image or images of a sample in multiple fields of view, and the image or images are automatically transmitted to a processing module and processed by the first processing module automatically in real-time based on a predefined criterion so as to determine coordinate information of an interested region in each field of view. The processing module also controls an illuminating assembly to illuminate the interested region of the sample according to the received coordinate information regarding to the interested region, with the illumination patterns changing among the fields of view.

Claims (37)

1. A system for image-guided microscopic illumination of varying patterns on a sample disposed on a stage of a microscope through a plurality of fields of view of the sample, comprising:

an imaging assembly comprising a camera, and an imaging light source;

an illuminating assembly comprising a pattern illumination device and an illuminating light source; and

a processing module configured to:

control the imaging assembly to acquire a first image of a first field of view of the sample, the first field of view being a subset of the sample;

process the first image automatically in real-time based on a predefined criterion, so as to determine coordinate information of an interested region in the first image;

control the illuminating assembly to illuminate the first field of view with a light pattern corresponding to the interested region of the first image according to the coordinate information of the interested region in the first field of view;

after the interested region of the first field of view has been fully illuminated by the illuminating assembly, move the microscope stage to subsequent fields of view of the sample to acquire images of the subsequent fields of view, the subsequent fields of view being subsets of the sample;

determine coordinate information of interested regions in the subsequent fields of view automatically in real-time based on the predefined criterion; and

control the illuminating assembly to illuminate the subsequent fields of view with light patterns corresponding to coordinate information of the interested regions in the subsequent fields of view, the light patterns varying through the first and subsequent fields of view.

2. The system according to claim 1 , wherein the sample comprises cells and the predefined criterion comprises subcellular features of the cells.

3. The system according to claim 1 , wherein the microscope includes an objective, the processing module being further configured to control the objective to move among the plurality of fields of view.

4. The system according to claim 1 , wherein the processing module is further configured to move the stage of the microscope among the plurality of fields of view.

5. The system according to claim 1 , wherein the sample is prepared with a photosensitizer and a chemical agent, the photosensitizer in the interested region being adapted to be excited by excitation energy provided by the illuminating light source in the light pattern to trigger the chemical agent to process a photochemical reaction, and wherein the photosensitizer and chemical agent are a single molecule.

6. A system for image-guided microscopic illumination of varying patterns on a sample disposed on a stage of a microscope through a plurality of fields of view of the sample, comprising:
