Spatial Analysis
SPATIAL ANALYSIS
Product Overview
Particularly useful to those involved in the immune-oncology field, the Spatial Analysis module offers a suite of subsequent analysis tools which can be used to identify proximity and relative spatial distribution of objects, cells, and/or features across single tissues or serial sections. This module is embedded within the HALO platform and can be used in conjunction with any of our cell-based analysis modules for brightfield or fluorescence.
Nearest Neighbor Analysis
Determine the average distance and number of unique neighbors between any two cell or object populations. The example below depicts pan cytokeratin positive cells (blue) and CD4 positive cells (red). Grey lines connect each CD4 positive cell to the nearest pan cytokeratin positive cell.
Proximity Analysis
Calculate the number of objects or cells within a certain distance of another object or cell. In the example below, the distance is set to 30 microns. CD8 positive cells within 30 microns of a pan cytokeratin positive cell (blue) are labeled green and CD8 positive cells greater than 30 microns from pan cytokeratin positive cell are labeled purple. A corresponding proximity histogram is automatically generated.
Infiltration Analysis
Determine the number of objects or cells within a set range of an annotated region of interest. Depicted below is a whole slide image stained with CD8. The tumor boundary has been defined/annotated in green. The infiltration analysis tool defines the invasive margin inside of tumor (yellow and red) and the invasive margin outside of the tumor (blue and purple) automatically. In this example, the distance is set to 500 microns around the annotated tumor boundary. CD8 positive cells are quantified within the margin. A histogram is automatically generated to reflect CD8+ cell density inside the tumor boundary (-1 to -500), at the tumor boundary (0), and outside the tumor boundary (+1 to +500) as shown in the image below.
Density Heatmaps
The density heatmap spatial analysis algorithm measures the density of a selected cell population from your object data within a certain radius. The scaling and colors of the markup are customizable. Reported in the summary data, the entire tissue area is analyzed and all cells of the desired population are counted. The average cell population and the average cell population density is calculated within the user-defined radius, as well as the minimum and maximum densities.
The tissue below is stained with an immune cell marker (red stain) and a tumor marker (DAB stain). The image was analyzed with the Multiplex IHC module to detect positivity and produce object data. The density heatmap analysis was used with a radius of 25 microns, measuring the density of immune cell positivity across the whole slide. The markup image, with adjustable transparency, depicts areas of higher density in red and orange, moderate density in yellow, and areas of lower density in green and blue.
The Spatial Analysis module integrates seamlessly into the HALO® platform and is compatible with a number of file formats.
