Quality assurance phantom for digital radiography

A method of creating a quality assurance phantom for an x-ray device, the method comprising:

• obtaining a spatial resolution test layer, the spatial resolution test layer including one or more traces disposed on a first surface of a substrate;
• obtaining a contrast layer to assess a contrast resolution, the contrast layer configured to provide two or more different contrast levels;
• and
• coupling the contrast layer to the first surface of the substrate of the spatial resolution test layer to form the quality assurance phantom.

A method of assuring the quality of digital imaging including a digital imaging system having a digital imaging sensor or phosphorus plate and an x-ray source, the method comprising the steps of:

• providing a digital imagining phantom comprising:
• a contrast layer, wherein the contrast layer is comprised of different contrast levels and is configured to assess the contrast resolution of the digital imaging system;
• a spatial resolution test pattern layer, wherein the spatial resolution test pattern layer includes copper tracings of variable pattern and thickness, wherein the spatial resolution test layer is configured to assess the spatial resolution of the digital imaging system;
• creating a baseline image, the creating step comprising:
• capturing an image with at least one of the digital imaging sensor and the phosphorus plate;
• assessing the image for contrast, spatial resolution, artifacts, and noise using the contrast layer and the printed circuit board spatial resolution test pattern layer;
• recording the results of the image assessment;
• and
• tracking and assessing the results over time.
