Specifications for Computed Radiography Systems

SCOPE

3.1 PURPOSE

The contract is Purchase of two (2) COTS Computed Radiography systems. The systems should be high-performance table-top flatbed scanners with contactless plate transport used for industrial radiography inspections. Each system shall comprise of a Computed Radiography scanner, high performance computer, and high-resolution monitor, software compatible to view results with Flash Image Enhancement, wall thickness measurement tools software and phosphor imaging plates.

The scanners will be used for the non-destructive inspection of ammunition and armor at Aberdeen Test Center and are intended to replace an X-ray Film processor. The system will be used in conjunction with an M9 Linear Accelerator and will need to produce radiographic images of heavy materials within Large Caliber ammunition and armor coupons.

3.2 GENERAL DOCUMENTATION

The following documents shall be supplied:

A complete set of Operator’s Manuals Certifications of Warranty of any/all commercial OEM equipment

3.3 ENVIRONMENT

The Computed Radiography Systems shall be operated in a field or shop environment with:

Ambient temperatures ranging from 15 to 35 degrees C Relative humidity between 15 and 80% (non-condensing) Available power 120 VAC (+/- 10%) at 50-60 Hz

3.4 REQUIREMENTS

The Computed Radiography Systems shall include the following items:

3.4.1 Computed Radiography Systems including scanner, high performance computer, software and phosphor imaging plates – (Qty: 2)

3.4.2 Fast Screening Plates Imaging Plates – (Qty: 2)

SRb: 3.5-4.0 lp/mm Signal to Noise Ratio: (150-200) Relative Sensitivity of the plate: (100-200)

3.4.3 Durable Imaging Plates – (Qty: 2)

SRb: 5.0 lp/mm Signal to Noise Ratio: (200-300) Relative Sensitivity of the plate: (50-100)

3.4.4 High Resolution Imaging Plates – (Qty: 2)

SRb: 7.0 lp/mm Signal to Noise Ratio: (300-400) Relative Sensitivity of the plate: (25-50)

3.5 QUALITY ASSURANCE AND WARRANTY PROVISIONS

Preservation, packaging, and packing shall be in accordance with the manufacturer’s commercial practice.

All components shall be covered by a full one-year warranty.

Shipping and handling shall be included.

Salient Characteristics for CR Scanner Scanner Specifications:

• Spatial Resolution:

• ≤ 40 µm (12.5 lp/mm), ensuring high-quality image detail.

• Bit Depth:

• 16-bit, providing a broad range of gray levels for improved image contrast and detail.

• Throughput:

• ≥ 28 plates/hour at 40 µm spatial resolution and film size of (10 x 40 cm /

4.5 x 17”), supporting efficient workflow.

• Transport System:

• Magnetic-based scanner with no contact on the imaging plate's image side, reducing wear and tear and ensuring better image quality.

• Portability:

• Weight ≤ 100 lbs, facilitating ease of movement and installation.

• Cassette Compatibility:

• Imaging plates can be exposed in any type of cassette and are directly removable and insertable into the scanner.

• Plate Acceptance:

• Capable of handling a wide range of sizes, shapes, and classes of imaging plates from 20mm to 1500 mm (0.75 inchese to 60 inches) in length.

• Ease of Use:

• No manual gain settings or photomultiplier adjustments needed for varying plate thicknesses.

• Compliance:

• Meets ISO 17636-2 Class A and B, ASME, and ASTM weld inspection standards, ensuring quality and standardization in inspection.

• Ambient Light Operation:

• Functional in ambient light conditions, reducing the need for controlled lighting environments.

Environmental Conditions:

• Operating Temperature Range:

• 15 to 35°C (59 to 95°F).

• Relative Humidity:

• 15 to 80% non-condensing.

• Power Requirements:

• 120 VAC (+/- 10%) at 50-60 Hz.

Software Features:

• Database Management:

• Includes archiving and retrieval functions for techniques

• Network Compatibility:

• Approved for ATC Network integration.

• Image Processing Tools:

• Image Marking Tools:

• Provides annotations, zoom, depth, and thickness measurement tools for enhanced analysis.

• Standardized Image Quality Tools:

• Includes Basic Spatial Resolution, Contrast-to-Noise Ratio, Signal-to-Noise Ratio, and Contrast Sensitivity measurements, adhering to ASTM and ISO standards.

• Image Processing Filter:

• Automatically processes and clarifies layered images with a single click, integrating high- and low-density details into one high-definition image.

• Operates as an overlay on the original image, preserving raw data and measurements.

• Commercial Availability:

• The scanner must be a commercially available, off-the-shelf product. It should be a standard product offered by the manufacturer and widely used in the industry.

• Delivery Time:

• The scanner must have a lead time of 4 weeks or less from the date of order confirmation to the date of delivery.
