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:
  1. 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.

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