Methods for feature analysis on consecutive tissue sections
First Claim
1. A method for feature analysis on consecutive tissue sections, comprising:
- obtaining a tissue specimen for analysis;
sectioning said tissue specimen into at least three consecutive tissue sections comprising a first tissue section, a second tissue section, and a third tissue section, said second tissue section originating from a volume of said tissue specimen between said first and third tissue sections;
applying at least a first biomarker to the first tissue section of said consecutive tissue sections, applying at least a second biomarker to the second tissue section, and applying at least a third biomarker to the third tissue section;
using a digital image analysis system comprising a camera and a display screen to capture at least a first digital image of the first tissue section, a second digital image of the second tissue section and a third digital image of the third tissue section; and
registering the digital images of the first and third tissue sections with the digital image of said second tissue section to digitally align each of the images;
characterized in that the method further comprises;
annotating one or more regions of interest within the second digital image of the second tissue section;
transferring said one or more annotated regions of interest from the second digital image to at least one of the first and third digital images that are digitally aligned therewith; and
deriving a tissue analysis score for each of said consecutive tissue sections.

Abstract
Feature analysis on consecutive tissue sections (FACTS) includes obtaining a plurality of consecutive tissue sections from a tissue sample, staining the sections with at least one biomarker, obtaining a digital image thereof, and identifying one or more regions of interest within a middle of the consecutive tissue sections. The digital images of the consecutive tissue sections are registered for alignment and the one or more regions of interest are transferred from the image of the middle section to the images of the adjacent sections. Each image of the consecutive tissue sections is then analyzed and scored as appropriate. Using FACTS methods, pathologist time for annotation is reduced to a single slide. Optionally, multiple middle sections may be annotated for regions of interest and transferred accordingly.
