Oval Profile Plot

Oval Profile Plot

Author: Bill O'Connell (woc at attbi.com)

History: 2002/02/15: First version
2002/07/31: Added "Radial Sums" option; x-axis labeled in degrees
2002/09/19: Fixed a bug in the "Along Profile" option
2003/01/23: Uses 65535 rather than 255 for drawing on 16-bit images
2005/06/27: Added "EquiCircumference" option. Compiles without errors.
2012/03/01: Compiles without warnings

Source: Oval_Profile.java

Installation: Download Oval_Profile.java to the ImageJ plugins folder, or subfolder, and compile and run it using Plugins/Compile and Run. Restart ImageJ and there will be a new Oval Profile command in the Plugins menu or submenu.

Description: This plugin takes the image region bounded by an oval region and samples the oval at N equal angles around the oval. The program can generate three types of profile plots:

Maximum intensity values along N radii from the oval center to oval points. This measure is called the circumferential profile and is used in Nuclear Medicine cardiac blood perfusion studies, in which short axis slices of the left ventricle are roughly doughnut shaped.

Radial Sums. Along each radius,from the oval center to periphery, interpolated pixel intensities are summed and plotted.
Pixel values along the oval.
