  The Nevanlinna transform K(z), of a measure and a real constant, plays an
important role in the complex analysis and more recently in the free
probability theory (boolean convolution). It is shown that its restriction
k(it) (the restricted Nevanlinna transform) to the imaginary axis can be
expressed as the Laplace transform of the Fourier transform (characteristic
function) of the corresponding measure. Finally, a relation between the
Voiculescu and the boolean convolution is indicated.
