DIAGNOSTIC IMAGING FOR DIABETIC RETINOPATHY

摘要

This disclosure relates to diagnostic imaging of a retina of a patient with diabetic retinopathy. A processor retrieves a first image of the retina captured at a first point in time and a second image of the retina captured at a second point in time after the first point in time. The processor aligns the first image to the second image to reduce an offset between non-pathologic retina features in the first image and the second image and obtains image objects related to diabetic retinopathy in the first image and the second image. The processor then calculates a numerical pathology score indicative of a progression of the diabetic retinopathy by calculating a degree of change of the image objects related to diabetic retinopathy between the aligned first and second images and finally, creates an output representing the calculated numerical pathology score.
