Among the promising medical applications, the opportunity to image organs with low water content and/or with air spaces, such as colon or lungs, has raised a considerable interest because conventional imaging techniques cannot provide good images of these hollow spaces and the surrounding tissues. Imaging of cerebral blood flow and angiography are also interesting applications. These applications HpG may become a useful tool for non-invasive investigation of human lung ventilation, giving access to static imaging during breathhold, dynamics of inspiration/expiration, and functional imaging and material studies too. We present the polarization system consisting of three main parts. The basic segment of the optical part is a commercially available Ti:Sa laser tunable in a wide wavelength range 680 nm – 1025 nm with the output optical power of around 1 W. The basic segments of the vacuum part are a turbomolecular-drag pumping station, vacuum pipelines, valves and glass cell with valves. The third part consists of an electronic control and RF system, an RF coil and Helmhotz coils. In this paper, the polarization system is described and the measured value of Rb absorption linewidth is published.
