Abstract
A method of processing optical coherence tomography angiography, OCTA, data comprising an array of columns of data elements to generate corrected OCTA data showing reduced projection artefacts in enface projection, the OCTA data having been generated from repeat B-scans, the method comprising: (i) calculating a correlation value indicative of a correlation between a first sequence of the data elements, whose respective locations within respective B-scans correspond to a location of a first data element within the array, and a second sequence of the data elements, whose respective locations within respective B-scans correspond to a location of a second data element within the array; (ii) calculating a correction for the second data element based on the first data element and the calculated correlation value; and (iii) applying the calculated correction to the second data element, wherein processes (i) to (iii) are performed multiple times to generate the corrected OCTA data.
