Dear Michael,
the valuable ImageJ-plugin "Radial Profile" sums the image values on
concentric circles and displays the normalized sums as a function of the
radii of these circles. Consequently, the result is a 1-dimensional
curve with the radius as the abscissa.
Due to the circular summing, this operation can't be reversed or, as
you've put it, it can't be "inverted".
What you may achieve however, is to generate a radially symmetric image
from a profile. If the profile is given analytically you can use
"Process > Math > Macro"
as it was suggested by Jerome Mutterer:

Here is his example macro using a shifted Gaussian profile:
newImage( "Image from Profile", "8-bit black", 256, 256, 1 );
run( "Macro...", "v=255*exp(-((d-50)*(d-50)/w)/2)" );
