Measurements of X-Ray Capillary Optics for Digital Mammography

Abstract

X-ray capillary optics present great potential in designing a mammographic imaging system with high resolution, enhanced contrast, a high dynamic range and a low absorbed dose to the patient. Well engineered optics can collimate, focus and filter x-rays and can magnify images or demagnify images to mate them to a direct x-ray detector. Measurements on two collimating prototypes as pre-patient optics and two linearly tapered optics as post-patient "scatter-rejection" devices are reported here. Preliminary scatter fraction measurements demonstrate an excellent ability to reject Compton scattered photons, implying enhanced contrast in medical imaging systems.
