To capture an image of the entire heart without any motion artifacts has been for a long time the motivation to develop advanced clinical X-ray computed tomography. Towards this aim, we invented the novel concept of computer tomography performed with two X-ray tubes and corresponding two X-ray detectors - dual-source computer tomography (DSCT). The major benefit of DSCT is its improved temporal resolution(83ms)independent of a patients heart rate. DSCT offers further advantages: The dose to the patient during a cardiac DSCT examination can be significantly reduced (about 50%) compared to the dose during an examination with conventional single X-ray tube CT. DSCT also makes a novel imaging application possible: Dual energy imaging with different kV settings for each X-ray tube. With dual energy CT, anatomical images that include characteristic information on body tissues can be obtained. We believe that dual source and dual energy imaging have the potential to open a new era of X-ray CT diagnosis.
