Fluoroscopy Grids - Video Lesson

An important component of most all fluoroscopic imaging systems is the simple grid. It has no moving parts, and it is not an electronic device. It's often taken for granted in terms of its importance in getting optimum fluoroscopic image quality. So let's take a look at its design and specifications. As with all grids used in medical imaging, They serve to remove a degree of scatter and secondary radiation and let the primary radiation through to a receptor. We know that x-ray photon interactions produce secondary and scatter radiations. The radiation that strikes the receptor is remnant and creates the image data. Grids function to intercept undesirable scatter and secondary radiation and permit the transmission of usable radiation towards the receptor.
