Point Sampled Intercepts

THE VOLUME WEIGHTED VOLUME OF MELANOMA CELL NUCLEI IN THE SKIN IS ESTIMATED WITH THE POINT SAMPLED INTERCEPTS PROBE

 

PSI-field

PSI cell

 

Section thickness required: thin sections

Orientation of tissue required: isotropic or vertical sections

Note: the example above is from a thin isotropic section, if it were a vertical section, the vertical direction must be indicated as it influences the placement of the lines.
