1. An x-ray transmissive window, comprising:a plurality of carbon nanotubes arranged into a patterned frame;the plurality of carbon nanotubes being linearly aligned and extending linearly between a base and a face of the patterned frame;at least one transmission passage defined in the patterned frame, the transmission passage extending from a base of the patterned frame to a face of the patterned frame; anda film carried by the patterned frame, the film at least partially covering the transmission passage while allowing transmission of x-rays through the transmission passage. 2. The window of claim 1, wherein the film is a polymeric film. 3. The window of claim 1, further comprising a gas barrier film layer disposed over the film. 4. The window of claim 1, further comprising an interstitial material, at least partially filling interstices between the carbon nanotubes and binding the nanotubes into a bonded mass. 5. The window of claim 4, wherein the interstitial material is selected from the group consisting of: Beryllium, Boron, Carbon, Magnesium, Aluminum, Diamond, Silicon, Silicon Carbide, Boron Carbide, Boron Nitride, Silicon Nitride and Beryllium Oxide. 6. The window of claim 4, wherein the at least one transmission passage has a diameter or opening size greater than 100 μm; and wherein the nanotubes arranged into the patterned frame define at least one interstitial material access hole extending from the base of the frame to the face of the frame and being substantially devoid of nanotubes and having a diameter or opening size of between 3 to 20 μm. 7. The window of claim 1, wherein the patterned frame includes:a series of intersecting walls formed by the nanotubes;the series of walls defining a plurality of passages with each of the passages being substantially devoid of material; andwherein the nanotubes of the walls are oriented substantially parallel to the passages. 8. An x-ray transmissive window, comprising:a plurality of carbon nanotubes arranged into a patterned frame;the plurality of carbon nanotubes being linearly aligned and extending linearly between a base and a face of the patterned frame;an interstitial material at least partially filling interstices between at least some of the carbon nanotubes;at least one transmission passage defined through the patterned frame;a film carried by the patterned frame, the film being operable to allow transmission of x-rays through the transmission passage. 9. The window of claim 8, wherein the film is a polymeric film. 10. The window of claim 8, further comprising a gas barrier film layer disposed over the film. 11. The window of claim 8, wherein the interstitial material is selected from the group consisting of: Beryllium, Boron, Carbon, Magnesium, Aluminum, Diamond, Silicon, Silicon Carbide, Boron Carbide, Boron Nitride, Silicon Nitride and Beryllium Oxide. 12. The window of claim 8, wherein the patterned frame includes a series of intersecting walls, the series of walls defining a plurality of passages with each of the passages being substantially devoid of material. 13. The window of claim 8, wherein the at least one transmission passage has a diameter or opening size greater than 100 μm; and wherein the nanotubes arranged into the patterned frame define at least one interstitial material access hole extending from the base of the frame to the face of the frame and being substantially devoid of nanotubes and having a diameter or opening size of between 3 to 20 μm. 14. A radiation detection system, comprising:an enclosure;a sensor, contained within the enclosure, the sensor being operable to detect x-rays entering the enclosure;an x-ray transmissive window attached to the enclosure, the window being formed of: a plurality of carbon nanotubes arranged into a patterned frame, the plurality of carbon nanotubes being linearly aligned and extending linearly between a base and a face of the patterned frame, the patterned frame including at least one transmission passage defined therethrough; anda film carried by the patterned frame, the film at least partially covering the transmission passage while allowing transmission of x-rays through the transmission passage. 15. The system of claim 14, wherein the film is a polymeric film. 16. The system of claim 14, further comprising a gas barrier film layer disposed over the film. 17. The system of claim 14, further comprising an interstitial material, at least partially filling interstices between the carbon nanotubes and binding the nanotubes into a solid mass. 18. The system of claim 17, wherein the interstitial material is selected from the group consisting of: Beryllium, Boron, Carbon, Magnesium, Aluminum, Diamond, Silicon, Silicon Carbide, Boron Carbide, Boron Nitride, Silicon Nitride and Beryllium Oxide. 19. The system of claim 17, wherein the patterned frame includes:a series of intersecting walls formed by the nanotubes;the series of walls defining a plurality of passages with each of the passages being substantially devoid of material; andwherein the nanotubes of the walls extend substantially parallel to the passages. 20. The system of claim 14, wherein the nanotubes arranged into the patterned frame define at least one interstitial material access hole extending from a base of the frame to a face of the frame and being substantially devoid of nanotubes and at least partially filled with interstitial material.
