Spatial Resolution (Image Receptor Factors) - Video Lesson

Hey, everybody. Welcome back. This lesson is about the image receptor that affect the spatial resolution of the radiographic image. Remember spatial resolution is the structural sharpness recorded in the radiographic image. And spatial resolution is a very important image quality factor. The image receptor is obviously a critical part of the image production process. The remnant beam has different signal intensities that correspond to the anatomy represented by that part of the beam. Since we can't see the x-ray beam directly, We measure it with the image receptor. The information in the remnant beam is collected by thousands of detector elements called Del's within the image receptor. So the image receptor is not one large detector, but rather a matrix of thousands of
