Аннотация:
In this work we study weighted Radon transforms in multidimensions. We inсtroduce an analog of Chang approximate inversion formula for such transforms and describe all weights for which this formula is exact. In addition, we indicate possible tomographical applications of inversion methods for weighted Radon transforms in 3D.
Ключевые слова:
weighted Radon transforms, inversion formulas.
