Grids (Intro) - Video Lesson

Hey, everybody. Welcome back. In this video, we're discussing radiographic grids. Radiographic grids have a very specific design and purpose. A grid uses a plate of thin lead strips to prevent scatter from striking the image receptor, and that improves image quality by increasing image contrast. Grids are not always necessary, but an x-ray operator must understand how they function and how to use them correctly. Failure to use grids correctly can result in non diagnostic images and excessive patient dose. Several types of x-ray imaging equipment use grids, including stationary x-ray rooms, fluoroscopy equipment, computed tomography and mammography. Grids are sometimes necessary because of scatter radiation. When the x-ray beam is passing through the patient,
