New grid design for a fluoroscopic spot film device.
A new grid design for a fluoroscopic spot film device is presented. Fluoroscopy is achieved with a conventional low ratio grid, while spot filming is done with a high ratio criss-cross grid. The result is a low patient radiation dose during fluoroscopy, while the high ratio grid during spot filming provides a significant increase in subject contrast.
