LEMC New Purchase Request Statement of Work

Cabinet X-Ray System

1. Requirement: Letterkenny Munitions Center has the requirement to purchase a turn-key, state-of-the-art, 7-axis, digital radiography computed tomography system. The system must be able to scan parts up to a 60” diameter and 60” in length. The system must be fully shielded and interlocked cabinet-style unit. It must comply with all applicable industry regulations and Food and Drug Administration (FDA) 21CRF1020.40. The system must include a flat panel detector, 225Kv Microfocus Tube, 450 HP Tube, DR Image processing acquisition workstation and software, and a separate CT reconstruction workstation including software and meet Technical Requirements listed below.

1.1 Specifications:

1.1.1 System Capabilities:

1.1.1.1 Advanced 2D x ray inspection, 2D CT Slice

reconstruction, CT volume reconstruction for 3D inspection, 3D internal and external surface scanning, and Measurement and Analysis tools.

1.1.2 System Specifics:

1.1.2.1 See Attached list of the specific salient characteristics.

1.1.3 Demonstration of Salient Characteristics: Failure to provide the following samples and demonstrations will prevent one from becoming technically acceptable.

1.1.3.1 Provide a sample part that is up to 25” in length and under 6” in width, that the seller must demonstrate the ability to use one continuous helical motion in which the sample is CT Scanned using a single automated spiral acquisition. This shall not be separate CT scans stitched together. This will demonstrate the spiral acquisition capabilities.

1.1.3.2 Provide a sample part that is up to 20” in length and under 20” in width, which will demonstrate the ability to seamlessly stitch together the 2D images from multiple projection angles, and reconstruct a single CT volume of the entire part. This will demonstrate the image stitching capabilities.

1.1.3.3 Provide a sample which demonstrates the ability to

automatically move the detector a sub pixel distance both horizontally and vertically, capturing 4 images within each pixel for each CT projection. The system shall be capable of performing sub-pixel resolutions scans in both step-scan and continuous-scan modes.

The result shall produce a CT voxel size equal to half that of a standard cone beam CT scan. This will demonstrate the sub-pixel resolution capabilities.

1.1.3.4 Provide a sample which demonstrates the ability of the system shall be capable of performing automated line scan imaging with a digital flat-panel detector for 2D scanning of elongated objects where parallax in one direction can cause image distortion. The 2D line scan (Simulated LDA scan) shall provide for the product to be scanned between the tube and detector with the option of using either a cone beam or collimated fan beam. The object length is to only be limited by the system scanning area. This 2D scanning method reduces or eliminates the cone angle artifacts caused by flat, planar features common in 2D DR imaging techniques. The detector shall be configurable to provide for faster frame rates/line rates through a reduced detector active area. This will demonstrate the DDA Line Scan (simulated LDA scan) capabilities.

1.1.3.5 Provide x ray simulation software that is representative of the actual system configuration including the Manipulator, x ray tube, detector, and scan envelope geometry. The simulation software must provide a polychromatic x ray beam representing the kV and current range of the actual system. It shall also provide for controls of the detector and motion system and complete image acquisition parameters for both 2D DR imaging a CT scanning. The software shall be capable of inserting a representative part file into the simulator for imaging and providing acquisition of full motion programs. The software shall provide for material alloy selection of the product sample as well as allow for inserting assemblies and fixtures of varying materials and x ray beam filters. The simulation software controls shall be representative of the actual system software controls. The sample must demonstrate within the simulation software, the creation of a CT data acquisition and a reconstruction data set of a representative part as well as a multi position DR motion control program which records all imaging technique and geometry parameters to a file. This simulation generation demonstration shall be performed on a different system than the actual system. This sample must also demonstrate the placement of the simulation file onto the actual x ray system along with the insertion of the actual part into the actual system to generate DR images from the simulation recorded motion control program and a CT Data set of the actual part. This will demonstrate the x ray system CT simulation and offline programming capabilities.
