Classification: CPC A  G | IPC A  G

Claim 10:
11. The apparatus according to claim 2, wherein:
the receiver module is configured to receive a sequence of B-scans, which has been generated by the OCT imaging device repeatedly scanning the scanned region of the retina over the time period, as the OCT image data;
the apparatus further comprises a B-scan processing module configured to segment each B-scan in the sequence of B-scans into a plurality of B-scan layers so that each B-scan layer comprises respective sections of the A-scans forming the B-scan, and concatenate corresponding B-scan layers from the segmented B-scans to generate sequences of concatenated B-scan layers;
the correlation calculator module is configured to calculate, for each of at least one sequence of concatenated B-scan layers of the sequences of concatenated B-scan layers, a respective rolling window correlation between concatenated B-scan layers in the sequence of concatenated B-scan layers and stimulus indicators in the sequence of stimulus indicators by:
calculating, for each stimulus indicator, a product of the stimulus indicator and a respective windowed portion of the sequence of concatenated B-scan layers comprising a B-scan layer of the B-scan layers which is based on a B-scan which has been generated by the OCT imaging device while the retina was being stimulated in accordance with the stimulus indicator; and
combining the calculated products to generate an indication of a response of a layer of the retina corresponding to the sequence of concatenated B-scan layers to the light stimulus.
