AbstractTo reduce the radiation exposure received by young scoliosis patients during treatment, six changes in technique were instituted: (1) a posteroanterior projection, (2) specially designed leaded acrylic filters, (3) a high-speed screen-film system, (4) a specially designed cassette-holder and grid, (5) a breast-shield, and (6) additional filtration in the x-ray tube the thyroid, breast, and abdominal areas were made on an Alderson phantom. They revealed an eightfold reduction in abdominal exposure for both the posteroanterior and the lateral radiographys. There was a twentyfold reduction in exposure to the thyroid for the posteroanterior radiography from 100 to less than five milliroentgens and for the lateral radiograph there was a 100-fold reduction from 618 to six milliroentgens. For the breasts there was a sixty-ninefold reduction from 344 to less than five milliroentgens for the posteroanterior radiography and a fifty-fivefold reduction from 277 to less than five milliroentgens for the lateral radiograph. These reductions in exposure were obtained without significant loss in the quality of the radiographs and in most instances with an improvement in the over-all quality of the radiograph due to the more uniform exposure.

@article{osti_6147182, What is the importance of filtration during a fluoroscopic examination?Beam Filtration
Added aluminum and/or copper filtration can reduce skin dose at the patient's entrance surface, while a low kVp produces a spectral shape that is well-matched to the barium or iodine k-edge for high contrast in the anatomy of interest.
What is contact shielding?Radiation used in radiology carries small risks of radiation damage. To minimise this damage to sensitive organs, contact shielding was used for many years. In contact shielding a shielding object (blanket, rubber mat…) with radiation absorbing material is used and placed in contact with the surface to be shielded.

Lead aprons and thyroid shields are the principal radiation protection tool for interventional radiologists, and they should be worn at all times during the procedure.
