Automated laser capture microdissection
Multiple different samples are obtained from a bulk material and are separately stained. The differently stained materials look different with the different stains but also have similar characteristics. A computer is used to reorient the images so that the samples are oriented with one another. The thus oriented samples can have their like parts either reoriented. Once the stained areas are analyzed, the identified area in the unstained sample can be removed by laser capture microdissection.
1. A method comprising:
obtaining multiple serial sections of sample material from a bulk sample;
staining at least two of said sections using different stains for each section;
obtaining images of said sections;
reorienting at least one image of said at least two sections that has been stained to overlap with that of at least one other section that is unstained using a computer; and
using said at least two sections that has been stained to determine a location on said at least one other section to carry out laser microdissection;
wherein the unstained section is in-between the stained sections.
2. A method as in claim 1 , wherein said using comprises forming instructions that automatically control laser microdissection using a computer.
3. A method as in claim 1 , wherein said using comprises remotely determining an area of interest from a remote location, and returning, from the remote location, information about the area of interest.
4. A method as in claim 1 , wherein said reorienting comprises carrying out crosscorrelation through a plurality of different rotations and translation values, and finding similarity values at said rotation and translation values.
5. A method as in claim 1 , wherein each stained region is stained to show different features.
6. A method as in claim 1 , further comprising finding an area of overlap between stained portions of the stained regions.
7. A method as in claim 1 , further comprising finding a median between stained portions of the stained regions.
8. A method, comprising:
slicing a bulk sample to form multiple sections from the bulk sample;
staining plural samples from the bulk sample using difference stains, and maintaining one of said samples as unstained, wherein the unstained section is in-between the stained sections;
obtaining plural different images from said stained samples and said unstained samples,
using a computer to orient the images so that similar parts of the images are in similar locations;
using the computer to find an area of overlap between the images; and
using a computer to produce output information that can be used to carry out laser microdissection on the unstained sample, based on information obtained from the stained sample.
9. A method as in claim 8 , wherein said output information is output to a laser microdissection tool.
