Fully automatic segmentation of the choroid in non-EDI OCT images of patients with multiple sclerosis
López-Varela, Emilio; Barreira, Noelia; Olivier Pascual, Nuria; García Ben, Emma; Rubio Cid, Sara (Elsevier, 2022)[Abstract]: Multiple Sclerosis (MS) is a chronic neurological disease, in which immune-mediated mechanisms lead to pathological processes of neurodegeneration. Optical coherence tomography (OCT) has recently begun to be ... -
Fully-Automatic 3D Intuitive Visualization of Age-Related Macular Degeneration Fluid Accumulations in OCT Cubes
López-Varela, Emilio; Vidal, Plácido; Olivier Pascual, Nuria; Novo Buján, Jorge; Ortega Hortas, Marcos (Springer, 2022-05)[Abstract]: Age-related macular degeneration is the leading cause of vision loss in developed countries, and wet-type AMD requires urgent treatment and rapid diagnosis because it causes rapid irreversible vision loss. ... -
Generation of synthetic intermediate slices in 3D OCT cubes for improving pathology detection and monitoring
López-Varela, Emilio; Barreira, Noelia; Olivier Pascual, Nuria; Arroyo Castillo, Maria Rosa; Penedo, Manuel (Elsevier B.V., 2023-09)[Absctract]: OCT is a non-invasive imaging technique commonly used to obtain 3D volumes of the ocular structure. These volumes allow the monitoring of ocular and systemic diseases through the observation of subtle changes ... -
