STATEMENT OF WORK

for

Accelerator X-Ray Imaging Acquisition System

1.0 INTRODUCTION

The Naval Surface Warfare Center, Indian Head Division (NSWC IHD), Non-Destructive Evaluation Branch has a requirement to purchase and install a digital detector array and acquisition system to convert x-ray energy into a useable signal for image interpretation and archival.

2.0 SCOPE

This Statement of Work describes and defines the procurement for the acquisition portion of an x-ray system. A digital detector array converts radiation into an electrical signal that is proportional to the amount of radiation dose received in a period of time. This image data as it is sent from the panel via a CAT 6 cable, must be received by the computer, processed and saved to a file or sent to another program. The synchronizer is required as communicates with the x-ray generating system and the image acquisition system such that they are coordinated. If x-rays are generated while the detector panel is accessing data, the image is corrupted. The Marietta synchronizer is the only known solution this requirement.

3.0 REQUIREMENTS

3.1 Hardware

3.1.1 Control Workstation

3.1.1.1 PC with Windows 10 Pro 64-bit

3.1.2 Synchronizer

3.1.2.1 Synchronizer configured for Varian M-series Linear Accelerator.

3.1.2.2 Synchronizer must have ability to be reconfigured to a different x-ray source by means of interchangeable chips without requiring re-soldering.

3.1.2.3 Synchronizer configured for Varex 4343HE Digital Detector Array.

3.1.2.4 Synchronizer must have ability to be reconfigured to a different imaging detector by means of interchangeable chips in a socket without requiring re-soldering.

3.1.3.7 Gigabit Ethernet Data Output

3.1.3.8 110 VAC Power Supply

3.1.4 150 foot detector extension communication cable

3.2 Software requirements

3.2.1 Image Capture Interface

3.2.1.1 Select the panel mode (1x1 or 2x2)

3.2.1.2 Select the number of frames for saving to be averaged from 1 to at least 32

3.2.1.3 Select the Detector Gain, supporting all gains supported by the panel

3.2.1.4 Select the Gain file to be used

3.2.1.5 Select the Offset file to be used

3.2.2 Image Display Interface

3.2.2.1 Select the minimum and maximum pixel values to display. Use linear lookup tables to determine what pixel value to display on screen

3.2.2.2 Use the mouse to adjust the minimum and maximum pixel values to display by holding down one mouse button and moving the mouse up or down and left and right. One direction should adjust the window width (the difference between the maximum and minimum pixel values) the other direction should adjust the window center (the halfway point between the min and max).

3.2.2.3 Graphically show the distribution of pixel values currently being displayed on the image in a histogram. Graphically show which part of the histogram is currently being displayed on the screen.

3.2.2.4 Display a part of the image by increasing the magnification, up to 800%. When using magnification, a small map should be on the screen which shows which part of the current image is being displayed. Moving the part of the image that is display should be done by holding down a mouse button and moving the mouse around.

3.2.2.5 Display the pixel value of the single pixel that is directly under the mouse while the mouse is over the image display. Display the X & Y coordinates of that pixel.

3.2.2.6 Include a tool to display the average pixel value and standard deviation of the pixels in a user selected sized box while the mouse is over the image display.

Display the X & Y coordinates of the center of the box.

3.3 Data Capture

3.3.1 Ability to communicate with a Varex 4343 series DDA and Varex XRD 1622 XP 14 DDA.

3.3.2 Capture binned data(2x2) when requested

3.3.3 Apply the selected Gain file to all acquired images

3.3.4 Apply the selected Offset file to all acquired images

3.3.5 Apply the selected Bad Pixel map to all acquired images

3.3.6 Capture the image using the selected number of averaged frames

3.3.7 Capture the image using the selected Detector Gain

3.4 Data Storage/Export

3.4.1 Ability to save images as 16-bit TIFF, BMP or JPG

3.4.2 Ability to send images to third party DICONDE analysis software including Yxlon, GEIT

Rhythm, and CareSteam Digital Viewing Software)
