Abstract: We discuss properties of a generalized Minkowski-Funk transform defined for a family of hypersurfaces. We prove two-side estimates and show that the range conditions can be written in terms of the reciprocal Funk transform. Some applications to the spherical mean transform are considered.

Keywords:  Funk transform of a density, conjugate points, reciprocal Funk transform, elliptic PDO, range conditions, thermoacoustic tomography, partial scan, Kaczmarz method.
