Supported Projects:

The support from LSI is mainly in the form of guidance and advisory groups but the projects are also economically supported, but only to a minor extent. All projects are today in an early feasibility test phase.

  • Liquid-Metal-Jet Hard-X-Ray Source

    The objective of this project is to create a compact hard-x-ray source with a brightness more than a hundred times higher than the best rotating-anode sources on the market today. This should be feasible by replacing the solid metal-plate anode with a microscopic high-speed liquid-metal-jet anode, since this configuration has much higher thermal limitations. This novel x-ray source would potentially enable higher spatial resolution and shorter exposure times. So called phase contrast imaging may also be a clinical reality.

  • New Instrument for Preclinical Imaging In Vivo

    Funtional imaging of larger living organisms is today mainly accomplished by PET, SPECT and fMRI. The problem is that the spatial resolution for realistic image acquisition times are of the order 1-3 mm. In spite of this limitation this is currently the fastest growing field in radiology. We propose a new imaging modality, based on the same principles as SPECT but with drastically improved efficiency and spatial resolution. This is achieved by incorporating a large number of x-ray lenses between the detectors and the object. In current SPECT, a pin-hole geometry is standard, that involves an unfortunate trade-off between efficiency and spatial resolution. Our solution would change this. Also a high resolution detector will be used and our calculations indicate that a spatial resolution for the system of 50 micrometers is possible, more than one order of magnitude improvement compared to current state-of-the-art. The new instrument may for example enable a more efficient process for development of new drugs.


  • Novel Concept for Child CT

    Every year over 100M CT-examinations are performed worldwide and only in the United States 600 000 of those were for children below the age of 15. There is a concern about the radiation dose delivered to the patients, in particular when they are at young age meaning they are more radiation sensitive. At the same time the requirement for high image quality is as high as ever. With new detector technology which counts each individual x-ray photon the information can be more optimally used and this translates into improved image quality and/or decreased radiation dose. We also believe introduction of state-of-the-art x-ray optics in CT may be an import step forward.
