Abstract: A method is disclosed for analysing an image to assess a condition of an organ of a patient represented in the image. The method includes initially selecting a spatial resolution for an inspection matrix having a number of inspection regions each delimiting a part of the image. The inspection matrix is applied to the image and the part of the image within each of the inspection regions is analysed to determine a condition thereof. The condition is compared with a predetermined criterion and, if the condition is deemed to satisfy the criterion, the inspection region is identified, e.g. by annotating it with a colour. Finally a quantitative measure of an extent of the condition in the image is provided that is based on a number of the identified or annotated inspection regions.
