 # Quick Overview
-* For 2D and 3D arrays 
-* parallel `radon` and `iradon`
-* parallel exponential `radon` and `iradon`
-* It is restricted to the incircle of radius `N ÷ 2 - 1` if the array has size `(N, N, N_z)`
-* based on [KernelAbstractions.jl](https://github.com/JuliaGPU/KernelAbstractions.jl)
-* tested on `CPU()` and `CUDABackend`
