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 (20)

1 . A method, comprising the steps of:

acquiring a first image of a first field of view of a first subset of a biological sample;

processing the first image automatically based on a predefined criterion to determine first coordinate information of a first region of interest of the first image;

illuminating the first field of view with a first light pattern corresponding to the first coordinate information of the first region of interest of the first image;

acquiring a second image of a second field of view of a second subset of the biological sample;

processing the second image automatically based on the predefined criterion to determine second coordinate information of a second region of interest of the second image;

illuminating the second field of view with a second light pattern different from the first light pattern and corresponding to the second coordinate information of the second region of interest of the second image.

2 . The method according to claim 1 , further comprising controlling a camera to acquire the first and the second images.

3 . The method according to claim 1 , further comprising controlling an imaging light source to provide imaging light to the biological sample when acquiring the first and second images.

4 . The method according to claim 1 , further comprising controlling an illuminating light source to provide illuminating light through an illuminating light path to illuminate the first and second fields of view of the biological sample to induce a photochemical reaction in the first and second regions of interest of the biological sample.

5 . The method according to claim 4 , further comprising controlling a pattern illumination device comprising a pair of scanning mirrors to direct the illuminating light to at least one targeted point within the first and second fields of view.

6 . The method according to claim 1 , wherein the first and second images are acquired through a microscope.

7 . The method according to claim 6 , further comprising loading the biological sample on a stage of the microscope.

8 . The method according to claim 1 , wherein a first processing module is used to perform the acquiring and processing steps.

9 . The method according to claim 8 , wherein a second processing module is used to perform the illuminating steps.

10 . The method according to claim 1 , further comprising moving the stage from the first field of view to the second field of view.

11 . The method according to claim 4 , wherein the photochemical reaction results in plurality of biotinylated amino acids in the first and second regions of interest of the biological sample.

12 . The method according to claim 11 , further comprising purifying the biotinylated amino acids to perform mass spectrometry for proteomic analysis.

13 . The method according to claim 1 , further comprising incubating the biological sample with a photosensitizer, a chemical agent and a tagging reagent before acquiring step, wherein the photosensitizer, the chemical agent and the tagging reagent are a single molecule with all three functions.

14 . The method according to claim 13 , wherein the chemical agent is conjugated with tagging reagent, and the photosensitizer and the chemical agent are separate molecules.
