We combine X-ray-specific tracer particles, a photon counting detector, and a liquid metal anode X-ray source to achieve O(1 kHz) X-ray imaging speeds in the laboratory, 15x faster than previous comparable studies. To demonstrate the capabilities of these imaging speeds, we conduct three experiments: 2D and 3D X-ray particle tracking velocimetry (XPTV) of Poiseuille pipe flow, 3D XPTV of flow around a Taylor bubble, and 3D scalar mixing with a laminar jet. These experiments demonstrate the performance improvement of combining the aforementioned elements, the applicability to multiphase flows and deforming systems, and the potential to capture scalar and vector quantities simultaneously. Most importantly, these experiments are conducted in the laboratory, showing that in-lab X-ray particle velocimetry techniques are now usable for a wider range of flows of interest.
