The selected voltage, current, frame rate, and source-to-detector distance combination should also allow enough the X-ray flux incident on the detector by penetration through the sample.
WebNov 14, 1996 · The magnitude of the image geometric unsharpness depends on the location in the field where the object is hit by the x- ray beam. This phenomenon is known as field characteristics and is caused by the target plane angulation. This yields different effective focal spot sizes and shapes when it is 'seen' from different directions and … WebThe amount of geometric unsharpness in a radiograph is affected by:(a) The source to film distance (b) The source to object distance(c) The size of the source (d) All of the above. …
