Electron paramagnetic resonance imaging (EPRI) allows the visualization of@free radicals in biological samples. To investigate the reduction of spin probes, the acquisition of 3D projection data has recently been achieved in 30 s in a live animal experiment and 6 s in a phantom experiment. However, image reconstruction and visualization of 3D objects were carried out after the data acquisition, which takes more time than the data acquisition itself. We report here the development of EPR imaging software that can reconstruct a 3D image while simultaneously acquiring projection data, and can visualize a 3D image immediately after reconstructing it.
