Abstrakt
The rising availability of medical imaging means increased radiation exposure for some populations. Research in the field of radiation dose regulation is necessary, especially for CT, which is a common part of diagnostic algorithms for most diseases.
Tin filtration, which dramatically reduces the radiation dose, has recently been introduced. The principle is to filter low-energy photons between the x-ray generator and the patient's body. Low-energy photons are responsible for image contrast and noise reduction.
