Motion blurMotion blur - 1. Movement of the patient or the x-ray tube during exposure results in blurring of the radiographic image. This loss of radiographic quality, called motion blur, may result in repeated radiographs and therefore should be avoided. 2. Patient motion is usually caused by motion blur. Suspend respiration for exposures, decrease exposure time, use a large SID and use a small OID. Transverse - across the table, at right angles to longitudinal. Longitudinal - along th...
