Segmentación automática de la aurı́cula izquierda en imágenes de tomograf\á computarizada cardiaca/Automatic segmentation of the left atrium in cardiac computed tomography
The present work proposes a technique for the automatic segmentation of the left atrium (LA) in 10 three-dimensional (3-D) cardiac images of multi-cut computed tomography, belonging to the same subject. The mentioned technique consists of the stages of pre-processing and segmentation. The pre-processing step includes two phases. In the first phase, in order to minimize both Poisson noise and the impact of the staircase artifact, a technique called global similarity enhancement is used. This type of enhancement consists in the application
