Radial Grid

[jessica1]

Hi there,

I am trying to get a radial grid overlay to measure intima-media thickness on some arterial cross sections.  I would like to overlay a radial grid from the centre of the vessel with x number of lines in 360 degrees.  This would allow me to define x number of locations at which to measure the thickness in a somewhat random fashion - ie not chosen on the basis of its thickness or thinness by myself or one of our undergraduate students.  I have tried the radial grid at
http://rsb.info.nih.gov/ij/plugins/radial-grid.html but do not seem to be able to get the grid in 360 degrees.

I am not very familiar with java, and would be grateful for any of your suggestions.

Thanks!

Jess

Hi again,

wayne kindly pointed out that it is possible to

"Just change this line

                for(int i=0;(i*degrees)<96;i++)

in Radial_Grid.java to

                for(int i=0;(i*degrees)<360;i++)

and recompile using Plugins>Compile and Run"

but I can't seem to figure out why it doesn't put a line at the starting position (and 180 degrees to that position) that it calculates all other angles from.

Thanks again,

Jessica
