Concepts for High-Resolution CT of the Breast

X-ray computed tomography (CT) has been proposed and evaluated recently as a potential alternative method for breast imaging Efforts so far showed success with respect to contrast-enhanced dynamic imaging, but suffered from limited spatial resolution The concept presented here builds upon micro-CT scanning approaches and aims at providing both high spatial resolution at around 100 μm for micro-calcification imaging and advanced dynamic scan capabilities with continuous acquisition and scan times of about 10 seconds for differential diagnosis of lesions To achieve this, spiral scan modes, slipring technology, high-resolution detectors and high-power micro-focus X-ray tubes are demanded The concept has been evaluated and confirmed by simulations and basic experiments; first clinical results are expected by the end of 2011.
