TomoJ is an ImageJ plug-in for tomographic reconstruction. It was designed for electron tomography, however any acquisition with parallel beam should work. TomoJ proposes the preprocessing and the registration of tilt-series prior to 3D reconstructions (WBP, ART, SIRT, OS-SART, compressed sensing). TomoJ is written in Java, the computations are multithreaded and reconstruction can be performed on CPU or GPU (OpenCL).
