  X-ray Fluorescence Ghost Imaging (XRF-GI) was recently demonstrated for x-ray
lab sources. It has the potential to reduce acquisition time and deposited dose
by choosing their trade-off with spatial resolution, while alleviating the
focusing constraints of the probing beam. Here, we demonstrate the realization
of synchrotron-based XRF-GI: We present both an adapted experimental setup and
its corresponding required computational technique to process the data. This
extends the above-mentioned potential advantages of GI to synchrotron XRF
imaging. In addition, it enables new strategies to improve resilience against
drifts at all scales, and the study of previously inaccessible samples, such as
liquids.
