When Should You Replace an Old X-Ray Grid?


X-ray grids are often thought of something that you purchase, install, and never think about again. They are sitting in your bucky tray invisible to you, that is, until they are not. Oftentimes, when upgrading to digital x-ray from film, CR, or even an older DR detector, users see grid artifacts on their [...]

What Effect Does A Moving Grid Have on DR Images?


JPI Healthcare Solutions frequently receives inquiries from both our dealer and end user networks. We very recently had a dealer inquire about the effect of a moving grid on images produced with Digital Radiography (DR) equipment. In short, the response is that the effects of moving grids on DR images are unpredictable and, [...]

How to Recognize a Bad Grid Moire Pattern: The image on the right. It’s created by the grid and detector interacting, like when you take a picture of a TV screen. Seeing a moire pattern means grid suppression is not working. This could be a software issue, or could be because the grid [...]

Back to Basics | X-Ray Grids


What is a Grid? A grid, fully named an “X-Ray Antiscatter Grid," is comprised of alternating lines of lead and another, much more X-ray transparent material, that is put directly in front of the detector or film. The purpose of them is to remove x-rays that have scattered and are not moving in [...]

Demands of Mammography Imaging


Mammography exams require an image resolution far above most general radiographic exams. Mammography machines must have a resolution below 200µm to accurately detect micro-calcification. This means that an x-ray tube with a target spot of 0.1 to 0.6mm must be used. Additionally, this means that the resolution of any detector for mammography must [...]

Evaluation of Mammography Grids


When evaluating the quality and performance of a mammography grid, it is difficult to perform a quantitative analysis. As a general method, the first step is to measure and compare the difference in film density (or detector exposure) across the entire area. The second step is to check the x-ray quality with a [...]

According to the American Cancer Society 2007 Global Facts and Figures, breast cancer is the first or second most commonly diagnosed form of cancer in many of the largest medical markets. According to the National Cancer Institute, more than 270,000 new cases are expected in the United States this year. Additionally, breast cancer [...]

Imaging Conditions in Moving Grid Technique for Reduction of Grid Line Artifacts


Antiscatter grids are considered an indispensable tool to improve image contrast and even decrease imaging doses if they are properly selected and installed specifically for the imaging system. However, the most critical problem remaining as an obstacle for their successful use in digital x-ray imaging is probably the the observation of the grid [...]
