Placing a wedge-type compensating filter over the upper thoracic vertebrae can help to equalize the density of the thoracic vertebrae, which tend to be thicker in the upper region. Positioning the patient's feet toward the cathode end of the tube can help to reduce scatter radiation and improve image contrast. Using a low kVp technique can also improve contrast and reduce scatter radiation. Using a high-ratio grid can be helpful for larger patients or when using higher kVp techniques, but it is not directly related to achieving uniform density on an AP thoracic projection.
