From: Macular Choroidal Thickness and Volume in Normal Subjects Measured by Swept-Source Optical Coherence Tomography Invest. Ophthalmol. Vis. Sci.. 2011;52(8):4971-4978. doi:10.1167/iovs.11-7729 Figure Legend: Weighted moving average applied to 3D raster scan protocol. (A) OCT image without weighted moving average. (B) OCT image with weighted moving average. In a raster scan protocol, 128 consecutive images, consisting of 512 A scans, were obtained in 0.8 second. To reduce a speckle noise, each image was enhanced by weighted moving average of three consecutive original images.
