Anti-scatter collimator for radiation imaging modalities

An anti-scatter collimator, comprising:

• a first anti-scatter structure defining a retaining member comprising:
• a first protruding member;
• a second protruding member spaced apart from the first protruding member to define a groove;
• and
• a support member extending between the first protruding member and the second protruding member, wherein the support member defines a bottom surface of the groove,
• wherein the first protruding member and the support member at least partially define an opening that passes through the first anti-scatter structure between a first side and a second side of the first anti-scatter structure;
• and
• a second anti-scatter structure comprising a septum disposed within the groove, wherein the first protruding member, the second protruding member, and the support member maintain a position of the septum relative to the first anti-scatter structure.

An anti-scatter collimator, comprising:

• a first layer defining a first retaining member at a first surface of the first layer, wherein the first layer has a first attenuation coefficient,
• a first anti-scatter structure defining a second retaining member at a first surface of the first anti-scatter structure, wherein:
• the first surface of the first anti-scatter structure faces the first surface of the first layer, and
• the first anti-scatter structure has a second attenuation coefficient that is greater than the first attenuation coefficient;
• and
• a second anti-scatter structure comprising a septum disposed between the first layer and the first anti-scatter structure and physically contacting the first retaining member and the second retaining member, wherein:
• the first retaining member and the second retaining member maintain a position of the septum relative to the first layer and the first anti-scatter structure, and
• the septum has a third attenuation coefficient that is greater than the first attenuation coefficient.
