Title: Erkki Somersalo: Innovator in Medical Imaging Technology
Introduction
Erkki Somersalo is a notable inventor based in Helsinki, Finland. He has made significant contributions to the field of medical imaging technology, holding 2 patents that showcase his innovative approach to X-ray imaging and impedance imaging.
Latest Patents
Somersalo's latest patents include a method and arrangement for medical X-ray imaging and reconstruction from sparse data. This invention relates to a medical X-ray device arrangement designed to produce three-dimensional information of an object. The device comprises an X-ray source that irradiates the object from various directions and a detector that captures the X-radiation to form projection data. The arrangement utilizes a prior distribution representing mathematical modeling of the object, an object image vector containing values of the X-ray attenuation coefficient, and a likelihood distribution that models the relationship between the object image vector and the projection data.
Another significant patent is the layer stripping process for impedance imaging. This method employs electrodes on the outer surface of a three-dimensional body to receive a set of current patterns. The resulting voltage patterns are measured at the outer boundary, and synthesized patterns are calculated for inner boundaries until reaching the center of the body. This process allows for the determination of various medium properties, such as electric conductivity and electric permittivity, which are essential for producing an image of the body.
