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 (32)

1 . A system for image-guided microscopic illumination of a biological sample, the system comprising:

a microscope;

an imaging assembly;

an illuminating assembly;

one or more processing modules operatively coupled to the microscope, the imaging assembly, and the illuminating assembly, wherein the one or more processing modules are configured to:

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

(b) process the first image automatically in real-time based on a predefined criterion, to determine coordinate information of one or more regions of interest in the first image, wherein the coordinate information comprises first coordinate information corresponding to a first targeted point and second coordinate information corresponding to a second targeted point;

(c) transmit the first coordinate information to the illuminating assembly;

(d) control the illuminating assembly to illuminate the first targeted point according to the first coordinate information;

(e) transmit the second coordinate information to the illuminating assembly;

(f) control the illuminating assembly to illuminate the second targeted point according to the second coordinate information; and

after the one or more regions of interest in the first field of view have been illuminated by the illuminating assembly, control the imaging assembly to acquire a subsequent image of a subsequent field of view, the subsequent field of view being a subset of the biological sample, and repeat (b)-(f) for the subsequent field of view.

2 . The system of claim 1 , wherein the coordinate information varies through the first and the subsequent field of view.

3 . The system of claim 1 , wherein the one or more processing modules are configured to execute (d) and (e) simultaneously.

4 . The system of claim 1 , wherein the one or more processing modules control the illuminating assembly to illuminate one targeted point at a time.

5 . The system of claim 1 , wherein the first coordinate information and the second coordinate information are digital numbers.

6 . The system of claim 5 , wherein the digital numbers are pairs of floating point numbers corresponding to XY-coordinate array of targeted points to be illuminated.

7 . The system of claim 5 , wherein (c) transmit the first coordinate information comprises converting the first coordinate information to first analog signal and (e) transmit the second coordinate information comprises converting the second coordinate information to second analog signal.

8 . The system of claim 7 , wherein the one or more processing modules are further operatively coupled to a signal converter, and wherein the signal converter is configured to covert the digital numbers to the analog signal.

9 . A method for image-guided microscopic laser illumination, comprising:

(a) acquiring a first image of a first field of view of a biological sample, the first field of view being a subset of the biological sample;

(b) processing the first image automatically in real-time based on a predefined criterion to determine coordinate information of one or more regions of interest in the first image, wherein the coordinate information comprises first coordinate information corresponding to a first targeted point and second coordinate information corresponding to a second targeted point;

(c) illuminating the first targeted point according to the first coordinate information;

(d) illuminating the second targeted point according to the second coordinate information; and

after the first targeted point and the second targeted point in the first field of view have been illuminated, acquiring a subsequent image of a subsequent field of view, the subsequent field of view being a subset of the biological sample, and repeating (b)-(d) for the subsequent field of view,

wherein the coordinate information varies through the first and the subsequent field of view.

10 . The method of claim 9 , wherein the method further comprises (e) transmitting the first coordinate information to the illuminating assembly, wherein (e) occurs prior to (c).

11 . The method of claim 9 , wherein the method further comprises (f) transmitting the second coordinate information to the illuminating assembly, wherein (c) and (f) occur simultaneously.

12 . The method of claim 9 , wherein, (e) transmitting the first coordinate information comprises converting the first coordinate information to first analog signal, and (f) transmitting the second coordinate information comprises converting the second coordinate information to second analog signal.

13 . The method of claim 9 , wherein the first targeted point and the second targeted point are illuminated one by one at a time.

14 . The method of claim 9 , wherein the first coordinate information and the second coordinate information are digital numbers.

15 . The method of claim 14 , wherein the digital numbers are pairs of floating point numbers corresponding to XY-coordinate array of targeted points to be illuminated.
