Title: Sakari Kettunen: Innovator in Medical Imaging Technology
Introduction
Sakari Kettunen is a notable inventor based in Helsinki, Finland. He has made significant contributions to the field of medical imaging, particularly in the area of cone-beam computed tomography (CBCT). His innovative approach addresses challenges related to patient movement during imaging procedures.
Latest Patents
Kettunen holds a patent for a "Patient movement correction method for cone-beam computed tomography." This method involves acquiring a set of X-ray projection images of the patient using X-ray imaging means. An initial projection geometry estimate is defined, which describes the spatial positions and orientation of the X-ray source and detector during image acquisition. The process includes computing an intermediate CBCT reconstruction and determining projection-image-specific corrective geometric transformations. A final CBCT reconstruction is then computed using the corrected estimate of the projection geometry, enhancing the accuracy of the imaging results.
