There are numerous applications for which is advantageous to obtain X-ray transmission data necessary for 3D computed tomography (CT) within seconds or faster. The required high frame rates for data acquisition became available during the last decade due to intensive synchrotron radiation sources together with appropriate X-ray imaging detectors. It will be shown in this work that sub-second recording of the full CT data set can be reached even in laboratory conditions employing high power microfocus tubes together with a semiconductor pixelated detector. As an example, bubbles nucleation and evolution during dissolving of a pill in the water, releasing carbon dioxide will be shown in 3D with 2 Hz time resolution.
