Abstract

Se proporciona un método para representar datos de imágenes de retina de tomografía de coherencia óptica, OCT, adquiridos por un escáner OCT, en el que cada ubicación de escaneo está asociada con una coordenada respectiva en un primer sistema de coordenadas, y cada píxel de los datos de imágenes de retina OCT representados está asociado. con una coordenada respectiva en un segundo sistema de coordenadas diferente, comprendiendo el método: recibir (S10) los datos de la imagen retiniana OCT; determinar (S60), para cada píxel de una matriz de píxeles, una coordenada respectiva en el primer sistema de coordenadas usando una transformación del segundo sistema de coordenadas al primer sistema de coordenadas; y calcular (S70) los valores de los píxeles utilizando las coordenadas determinadas en el primer sistema de coordenadas para interpolar entre los valores de píxeles de los datos de la imagen retiniana OCT. La coordenada respectiva en el primer sistema de coordenadas para cada píxel se determina usando: un primer mapeo para convertir la coordenada del píxel de la matriz de píxeles en el segundo sistema de coordenadas en una coordenada en un primer sistema de coordenadas del mundo real; un segundo mapeo para convertir la coordenada del píxel de la matriz de píxeles en el primer sistema de coordenadas del mundo real en una coordenada en un segundo sistema de coordenadas del mundo real; un tercer mapeo para convertir la coordenada del píxel de la matriz de píxeles en el segundo sistema de coordenadas del mundo real en un conjunto de valores de parámetros de escaneo OCT indicativos de una ubicación dentro del escaneo realizado por el escáner OCT; y un cuarto mapeo para convertir el conjunto de valores de parámetros de escaneo OCT a la coordenada del píxel en el primer sistema de coordenadas.
