A desktop tomography system, based on laser-interaction with a gas puff target, which results in efficient plasma formation emitting in the soft X-ray (SXR, Lambda = 0.1 - 10 nm) region, was developed at IOE-WAT (Warsaw, Poland). The system, coupled with an ellipsoidal condenser and a Fresnel zone-plate and working in the 'water window' spectral range (Lambda = 2.3 - 4.4 nm) at the quasi-monochromatic He-like nitrogen spectral line (Lambda =2.88nm), allows acquiring images approaching a resolution of few microns. The development of such setup offers the possibility to obtain a reconstruction of three-dimensional images in a laboratory environment, without the involvement of large 'photon facilities'. Details about the system and its optimization as well as some imaged samples will be presented and discussed.
