X-ray Extreme-Range Non-Imaging Analysis (XENA)

Background
The Defense Advanced Research Projects Agency (DARPA) is seeking innovative approaches to enhance low signal-to-noise images in long-standoff X-ray scenarios, particularly where motion blur is present.

The X-ray Extreme-Range Non-Imaging Analysis (XENA) program aims to develop algorithmic toolsets capable of making useful inferences in imaging situations lacking prior information about the object's interior composition. This program focuses solely on algorithm development and excludes advancements in X-ray source or detector hardware.

Work Details
Performers will be required to deliver algorithmic toolsets that can create useful inferences in terrestrial or aerial imaging scenarios without prior knowledge of the object's interior. The program emphasizes the following technical challenges:

1) Long Range: Development of methods for X-ray Computed Tomography (CT) at slant ranges of 500 to 5,000 meters, with applications including food processing quality control, customs cargo inspection, non-destructive inspection of turbine blades, and monitoring structural integrity during rocket static fires.

2) Motion Blur: New processing methods must address motion blur compensation, particularly for non-destructive inspections of complex moving mechanical parts without disassembly. The program assumes the use of standard commercially available Linear Accelerator (LINAC) sources and requires methods that work with hard X-rays (≥150 keV).

Period of Performance
The contract's period of performance will span multiple phases as outlined in the solicitation, focusing on the development and evaluation of proposed algorithms over an extended timeframe.

Place of Performance
The geographic location for performance may include various sites relevant to the imaging applications discussed, although specific locations are not detailed in the solicitation.
