发明名称 METODO PER ELIMINARE ARTEFATTI DA CODIFICA DI FASE IN UN'IMMAGINI DI RISONANZA MAGNETICA
摘要 <p>A method for eliminating artifacts from a magnetic resonance image begins with the steps of obtaining a first image (100a), using a phase coding along columns, and a second image (100b), using a phase coding along rows. Both images (100a, 100b) comprise a plurality of portions (101), each having a determined intensity value i arranged in a matrix structure (m-n), i.e. comprising m rows and n columns. The images (100a, 100b) are subject to a processing sequence that provides a comparative analysis by columns carried out comparing the corresponding columns and calculating the number of different portions, i.e. having a different intensity average value (imi?im2). The images (100a, 100b), furthermore, are subject to an analysis by rows that provides a comparison between the corresponding rows and calculating the number of different portions, i.e. portions having a different intensity average values (imi?im2). This way, a first and a second derived image of I generation are obtained, improved with respect to the starting images [Fig. 1].</p>
