ANTI-SCATTER COLLIMATOR FOR RADIATION IMAGING MODALITIES

Among other things, an anti-scatter collimator is provided including a first layer defining a first retaining member at a first surface. A second layer defines a second retaining member at a first surface that faces the first surface of the first layer. A septum is disposed between the first layer and the second layer and physically contacts the first retaining member and the second retaining member. The first retaining member and the second retaining member maintain a position of the septum relative to the first layer and the second layer. The septum has a third attenuation coefficient that is greater than a first attenuation coefficient of the first layer and a second attenuation coefficient of the second layer. An end support is attached to the first layer and to the second layer. The end support borders an end of the septum. 除其他方面外，本公开提供了一种防散射准直器，所述防散射准直器包括第一层，所述第一层在第一表面处限定第一保持构件。第二层在面向所述第一层的所述第一表面的第一表面处限定第二保持构件。隔板设置在所述第一层和所述第二层之间，并且物理接触所述第一保持构件和所述第二保持构件。所述第一保持构件和所述第二保持构件保持所述隔板相对于所述第一层和所述第二层的位置。所述隔板具有大于所述
