Detection of Architectural Distortion in Prior Mammograms via Analysis of Oriented Patterns
Published on: August 30, 2013
Summary
Simulating mammography X-ray spectra using different anode and filter combinations was tested. Results show spectral shape can be moderately simulated, but useful output is always reduced compared to direct methods.
Area of Science:
- Medical Physics
- Radiological Imaging
- X-ray Spectroscopy
Background:
- Simulating molybdenum (Mo)-anode spectra for mammography using tungsten (W)-anode tubes with Mo filters has been explored.
- Generating W-like continua for xeromammography via heavy aluminum (Al) filtration of Mo-anode tubes has also been reported.
Purpose of the Study:
- To evaluate the success of simulated X-ray spectra for mammography.
- To compare spectral shapes and exposure levels of simulated versus original spectra.
Main Methods:
- Utilized silicon-lithium (Si(Li)) spectrometry to measure spectral shapes and exposure levels.
- Compared Mo-anode/Al-filter with W-anode/Al-filter combinations.
- Compared W-anode/Molybdenum (Mo)-filter with Mo-anode/Mo-filter combinations.
Main Results:
- Spectral shape simulation was moderately successful under certain circumstances.
- All simulations resulted in reduced useful output compared to the original spectra.
- Direct use of the desired anode consistently yielded better results than simulations.
Conclusions:
- Simulating X-ray spectra for mammography is less effective than using the intended anode material directly.
- Current simulation techniques reduce the overall useful radiation output.
- Direct anode selection is the preferred method for optimal mammographic imaging.
