Dose reduction in paediatric radiology using rare earth filtration

Area of Science:

• Medical Physics
• Radiological Imaging
• Materials Science

Background:

• Rare earth elements are recognized for their potential to reduce radiation dose in medical imaging.
• Chemical stability and atmospheric resistance are crucial properties for filters used in radiological procedures.

Purpose of the Study:

• To evaluate the efficacy of erbium (Er) and samarium (Sm) filters in reducing radiation dose during pediatric radiological procedures.
• To compare the performance of rare earth filters against conventional aluminum filters.

Main Methods:

• Paediatric radiological procedures were conducted using Er and Sm filters.
• A comparative analysis was performed against a standard aluminum filter.
• Image quality and radiation dose were assessed for each filter type.

Main Results:

• The introduction of Er and Sm filters resulted in a radiation dose reduction of up to twofold.
• No discernible deterioration in image quality was observed with the rare earth filters.
• Rare earth filters demonstrated superior dose reduction capabilities compared to aluminum filters.

Conclusions:

• Erbium and samarium filters are effective in reducing radiation dose in pediatric radiology.
• These rare earth filters provide a viable alternative to conventional aluminum filters, enhancing patient safety.
• The use of rare earth filters can lead to significant dose savings without compromising diagnostic image quality.
