Abstract

One of the important causes of loss of resolution in a radiographic imaging system is the finite size and shape of the x-ray focal spot (1-4). Other factors are patient motion and the limited resolution of the image receptor, primarily due to the lateral spread of light from the intensifying screens within the x-ray cassette. The relative importance of each of these factors is inter-dependent as shown below.
