Abstract

Medical imaging was one of the earliest applications of x radiation and remains one of the most common and most important. Despite the advent of ultrasound and magnetic resonance imaging, x-ray imaging is still the most widely used medical imaging modality. Its low cost and ease of use are critical for mass screening, for example in cancer detection. The recent invention of Kumakhov polycapillary x-ray optics allows for a new mechanism of control of broadband x-ray radiation for imaging. Polycapillary x-ray optics provide nearly complete scatter rejection, and can be used to magnify or demagnify the x-ray image without conversion to visible photons. Measurements have been made of the performance of prototype magnifying antiscatter optics. Significant contrast enhancement and resolution improvement have been measured. The potential application of polycapillary optics to focused beam therapy is also discussed.
