Query: A new imaging technology based on Compton X-ray scattering   We describe a feasible implementation of a novel X-ray detector for highly
energetic x-ray photons with a large solid angle coverage, optimal for the
detection of Compton x-ray scattered photons. The device consists of a
20~cm-thick sensitive volume filled with xenon at atmospheric pressure. When
the Compton-scattered photons interact with the xenon, the released
photoelectrons create clouds of secondary ionization, which are imaged using
the electroluminescence produced in a custom-made multi-hole acrylic structure.
Photon-by-photon counting can be achieved by processing the resulting image,
taken in a continuous readout mode. Based on Geant4 simulations, by considering
a realistic detector design and response, we show that photon rates up to at
least $10^{11}$ ph/s on-sample ($5~{\mu}$m water-equivalent cell) can be
processed, limited by the spatial diffusion of the photoelectrons in the gas.
Illustratively, if making use of the Rose criterion and assuming the dose
partitioning theorem, we show how such a detector would allow obtaining 3d
images of $5~{\mu}$m-size unstained cells in their native environment in about
24~h, with a resolution of 36~nm.
