  The monogenic Hua-Radon transform is defined as an orthogonal projection on
holomorphic functions in the Lie sphere. Extending the work of Sabadini and
Sommen, J. Geom. Anal. 29 (2019), 2709-2737, we determine its reproducing
kernel. Integrating this kernel over the Stiefel manifold yields a linear
combination of the zonal spherical monogenics. Using the reproducing properties
of those monogenics we obtain an inversion for the monogenic Hua-Radon
transform.
