Nordic guidelines for dose reduction to radiosensitive organs of the patient in conventional radiography and fluoroscopy

PA projections PA projections are in most cases the best projection for reducing dose to many of the radiosensitive organs. Since only about 1 % of the incident radiation to the patient will reach the detector, dose will be reduced significantly to organs on the ventral side compared to AP projections. In some cases, the use of PA projections will also compress the body to some degree, thus reducing the dose.
