Abstract

Breast imaging using monochromatic x-rays promises lower dose and better image quality relative to conventional approaches. It has been proposed that the use of coated mirrors capable of mono-chromatic x-ray hard spectra have the capability of reducing ionizing radiation exposure while also improving image quality during x-ray medical screening procedures. This research study is centered around screening for breast cancer using Digital Mammography (DM) technique. In this work we present a simplified prototype system developed at DTU Space and implemented to validate the proposed Wolter type I design. The experimental setup consists of a source up to 40 keV, a high-resolution roto-translation mechanical support and an advanced high resolution (55 micron), energy-sensitive Si detector with quantum efficiency (20% @22 keV). For testing, phantom objects will be used as samples, allowing for a real-world realistic assessment of the use of space technology for breast screening. In this work, experimental measurements of absorbed dose reduction and contrast-to-noise ratio are reported.
