As described in the methods of the present invention, x-ray photons derived from a microscopic solid-density plasma that is produced by optically focusing a high power laser beam upon a high atomic number target, may be use for phase-contast medical microimaging and also for absorptive microradiography. As described in the methods of the present invention, x-rays derived from a microscopic solid-density plasma are utilized as object illumination sources that are microscopic in at least one direction (so that ultrathin slicebeams and fan-beams are allowed, as are linear arrays of numerous clusterd parallel microbeams). Collimating optical devices of prior art are required.
