A method (188, 190) for generating a wide field optical coherence tomography image of a portion of a sample, wherein the method comprises: creating a surface map of the sample; acquiring raw OCT data of the portion of the sample based on the surface map; generating a plurality of OCT images from the raw OCT data; and combining two or more OCT images of the plurality of OCT images (282a-282d, 292a-292c) to create the wide field OCT image by: aligning a first OCT image (282a, 292a) with a neighbouring OCT image (282b, 292b); and overlaying (242, 262) a portion of the first OCT image over a portion of the neighbouring OCT image to create the wide field OCT image by; creating (240, 260) a plurality of intermediary composite images (286, 296) by overlaying a portion of the first OCT image over a portion of the neighbouring image, wherein each intermediary composite image includes a different amount of overlap between the OCT image and the neighbouring image; determining (242, 262) an entropy associated with each intermediary composite image; selecting (263, 264) the intermediary composite image (312a, 312b, 312c, 312d, 312e) associated with a lowest entropy value as the composite OCT image for the first OCT image and the neighbouring OCT image; and recording the amount of overlap associated with the selected intermediary composite image. creating a surface map of the sample; acquiring raw OCT data of the portion of the sample based on the surface map; generating a plurality of OCT images from the raw OCT data; and combining two or more OCT images of the plurality of OCT images (282a-282d, 292a-292c) to create the wide field OCT image by: aligning a first OCT image (282a, 292a) with a neighbouring OCT image (282b, 292b); and overlaying (242, 262) a portion of the first OCT image over a portion of the neighbouring OCT image to create the wide field OCT image by; creating (240, 260) a plurality of intermediary composite images (286, 296) by overlaying a portion of the first OCT image over a portion of the neighbouring image, wherein each intermediary composite image includes a different amount of overlap between the OCT image and the neighbouring image; determining (242, 262) an entropy associated with each intermediary composite image; selecting (263, 264) the intermediary composite image (312a, 312b, 312c, 312d, 312e) associated with a lowest entropy value as the composite OCT image for the first OCT image and the neighbouring OCT image; and recording the amount of overlap associated with the selected intermediary composite image. aligning a first OCT image (282a, 292a) with a neighbouring OCT image (282b, 292b); and overlaying (242, 262) a portion of the first OCT image over a portion of the neighbouring OCT image to create the wide field OCT image by; creating (240, 260) a plurality of intermediary composite images (286, 296) by overlaying a portion of the first OCT image over a portion of the neighbouring image, wherein each intermediary composite image includes a different amount of overlap between the OCT image and the neighbouring image; determining (242, 262) an entropy associated with each intermediary composite image; selecting (263, 264) the intermediary composite image (312a, 312b, 312c, 312d, 312e) associated with a lowest entropy value as the composite OCT image for the first OCT image and the neighbouring OCT image; and recording the amount of overlap associated with the selected intermediary composite image. creating (240, 260) a plurality of intermediary composite images (286, 296) by overlaying a portion of the first OCT image over a portion of the neighbouring image, wherein each intermediary composite image includes a different amount of overlap between the OCT image and the neighbouring image; determining (242, 262) an entropy associated with each intermediary composite image; selecting (263, 264) the intermediary composite image (312a, 312b, 312c, 312d, 312e) associated with a lowest entropy value as the composite OCT image for the first OCT image and the neighbouring OCT image; and recording the amount of overlap associated with the selected intermediary composite image.
