Abstract

An improved diagnostic resolution of digital slide images is obtained by scanning a first digital slide image at diagnostic resolution that is then deconvolved into separate images with one stain per image. The single stain images are then enhanced with image adjustments and/or processed with image analysis algorithms. The resulting single image data sets from the image analysis algorithms can then be stored. Additionally, the resulting enhanced single images can be recombined into a second digital slide image at diagnostic resolution that is also enhanced.

First claim

What is claimed is:

1. A computer implemented method for improving the image quality of a digital slide image comprising:
one or more processors performing steps comprising:
receiving a navigation instruction identifying at least one portion of a digital slide image of a tissue sample;
acquiring and displaying the identified at least one portion of the digital slide image of a tissue sample;
determining whether the resolution of the at least one portion of the digital slide image of a tissue sample is acceptable based on an indicator;
accepting the identified at least one portion of the digital slide image of a tissue sample when indicated that the resolution is acceptable; and
acquiring and displaying a higher resolution image of the at least one digital slide image of a tissue sample when it is determined that the resolution is unacceptable.

2. The method of claim 1 further comprising, receiving the acceptable identified at least one portion of the digital slide image of a tissue sample at diagnostic resolution.

3. The method of claim 1 further comprising, deconvolving the digital slide image into a plurality of single images having one stain type per single image.

4. The method of claim 1 further comprising, adjusting one or more of the plurality of single images with an image analysis algorithm to optimize the quality of the plurality of single images.

5. The method of claim 4 further comprising, recombining one or more of the plurality of optimized single images into a second digital slide image at diagnostic resolution.
