Abstract

Claims (33)

1 . A method comprising:

positioning a slide that includes a concave region that is formed in a top surface of the slide and that can contain an object, such that a focal point of an objective lens of a fluorescence lifetime imaging microscopy (FLIM) device is within an area of the concave region between a bottom surface of the concave region and the top surface of the slide; and

using the FLIM device to capture a sequence of wide field images of a portion of the object within a field of view of the objective lens; and

wherein positioning the slide includes moving the slide laterally relative to the objective lens to a sequence of different slide positions such that a different portion of the concave region is within the field of view of the objective lens at each different slide position; further including:

at each different slide position, using the FLIM device to capture a sequence of wide field images of an entire portion of the object within the field of view of the objective lens at the different slide position.

2 . The method of claim 1 ,

wherein positioning the slide includes positioning the slide such that the focal point of the objective lens is within the object contained within the concave region.

3 . The method of claim 1 ,

wherein using the FLIM device to capture the wide field image of the object within the field of view of the objective lens includes simultaneously capturing the wide field image of the entire portion of the object within the field of view of the objective lens.

4 . The method of claim 1 ,

wherein using the FLIM device to capture the sequence of wide field images of the object within the field of view of the objective lens includes capturing a frequency domain wide field image.

5 . A system comprising:

one or more slides each including a concave region suitable to contain an object and each including identifying information thereon;

a fluorescence lifetime imaging microscopy (FLIM) device that includes an objective lens;

a reader configured to read the identifying information included on the one or more slides;

a stage positioned opposite the objective lens of the FLIM device and positioned opposite the reader;

a shuttle moveably mounted to the stage and holding the one or more slides;

one or more motors configured to impart motion to the shuttle;

a computing machine configured with instructions to perform operations including:

causing the one or more motors to impart motion to the shuttle to position at least one of the slides held by the shuttle such that the reader can read the identifying information on the at least one slide;

causing the reader to read the identifying information on the at least one slide;

causing the one or more motors to impart motion to the shuttle, based upon the identifying information read by the reader, to vertically position the at least one

slide relative to the objective lens such that a focal point of the objective lens is within an area of the concave region of the at least one slide between a bottom surface of the concave region and a top surface of the at least one slide; and

causing the FLIM device to capture a sequence of wide field images of a portion of an object within the concave region of the at least one slide that is within a field of view of the objective lens.

6 . The system of claim 5 ,

wherein causing the one or more motors to impart motion to the shuttle, based upon the identifying information read by the reader, to vertically position the at least one slide relative to the objective lens, includes imparting motion to position the at least one slide such that the focal point of the objective lens is within the object contained within the concave region of the at least one slide.

7 . The system of claim 5 further including:

causing the one or more motors to impart motion to the shuttle, based upon the identifying information read by the reader, to move the at least one slide laterally relative to the objective lens to a sequence of different positions such that a different portion of the concave region of the at least one slide is within the field of view of the objective lens at each different slide position; further including:

at each different slide position, causing the FLIM device to capture a wide field image of a portion of the object within the concave region of the at least one slide that is within the field of view of the objective lens at the different slide position.

8 . The system of claim 5 ,

wherein causing the FLIM device to capture the wide field image of the object within the field of view of the objective lens includes causing the FLIM device to simultaneously capture the wide field image of an entire portion of the object within the field of view of the objective lens.

9 . The system of claim 5 ,

wherein causing the FLIM device to capture the sequence of wide field images of the object within the field of view of the objective lens includes causing the FLIM device to capture a sequence of frequency domain wide field images.
