An interwoven multi-aperture collimator for three-dimension radiation imaging applications is disclosed. The collimator comprises a collimator body including a plurality of apertures disposed in a two-dimensional grid. The collimator body is configured to absorb and collimate radiation beams emitted from a radiation source within a field of view of said collimator. The collimator body has a surface plane disposed closest to the radiation source. The two-dimensional grid is selectively divided into at least a first and a second group of apertures, respectively defining at least a first view and a second view of an object to be imaged. The first group of apertures is formed by interleaving or alternating rows of the grid, and the second group of apertures is formed by the rows of apertures adjacent to the rows of the first group. Each aperture in the first group is arranged in a first orientation angle with respect to the surface plane of said collimator body, and each aperture in the second group is arranged in a second orientation angle with respect to the surface plane of said collimator body such that the apertures of the first group are interwoven with the apertures of the second group.Se describe un colimador entretejido de múltiples aberturas para las aplicaciones de imagenología por radiación tridimensional. El colimador comprende un cuerpo de colimador que incluye una pluralidad de aberturas ubicadas en una rejilla bidimensional. El cuerpo de colimador se configura para absorber y colimar los haces de radiación emitidos desde una fuente de radiación dentro de un campo visual del colimador. El cuerpo de colimador tiene un plano superficial ubicado lo más cerca posible a la fuente de radiación. La rejilla bidimensional se divide selectivamente en por lo menos un primer y segundo grupos de aberturas, que respectivamente definen por lo menos una primera vista y una segunda vista de un objeto que será visualizado. El primer grupo de aberturas es formado entrelazan
