What is PD IEC TR 60522‑2 about?
PD IEC TR 60522 discusses diagnostic X-rays for medical electrical equipment. PD IEC TR 60522‑2 lays out guidance on quality equivalent filtration and permanent filtration with regards to the requirements of IEC 60522-1 and its modifications versus IEC 60522:1999.
In PD IEC TR 60522‑2 for ease of use, the term “radiography” is used for applications within the high voltage range 50 kV to 150 kV, although strictly speaking the defined term “radiography” does not limit the high voltage.
Who is PD IEC TR 60522‑2 for?
PD IEC TR 60522‑2 on quality equivalent filtration and permanent filtration for diagnostic X-ray is useful for:
- X-ray medical electrical equipment manufacturers
- Medical electrical equipment test centres
- Regulatory authorities
Why should you use PD IEC TR 60522‑2?
Filtration is required to absorb the lower-energy x-ray photons emitted by the tube before they reach the target. The use of filters produces a cleaner image by absorbing the lower energy x-ray photons that tend to scatter more.
PD IEC TR 60522-2 guideline provides details about the influence of high voltage and of the atomic number of filter material, requirements on the high voltage, filtering material – representative target angle, radiation beam simulations, and quality equivalent filtration for quality equivalent filtration and permanent filtration for diagnostic X-ray equipment. This improves the quality equivalent filtration of diagnostic X-ray equipment.
