Article
Purpose: Today's standard imaging technique in interventional radiology is the single- or biplane x-ray fluoroscopy which delivers 2D projection images as a function of time (2D+T). This state-of-the-art technology, however, suffers from its projective nature and is limited by the superposition of the patient's anatomy. Temporally resolved tomogra...

Conference Paper
PURPOSE 4D angiography provides both morphological and functional information about the vasculature. Since the volume of interest (VOI) is irradiated multiple times, concerns about high radiation dose have prevented its routine clinical adoption. This first-in-man pilot study evaluates potential dose savings from prior-image constrained compressed...
Conference Paper
Mouse models of cardiac diseases have proven to be a valuable tool in preclinical research. The rapid heart and respiratory rates of free breathing mice and the consequent technical challenges up to now prohibit in vivo perfusion studies, e.g. of the myocardium, even if gating methods are applied. This makes a sacrification of the animals unavoidab...
Conference Paper
4D (=3D+time) interventional image guidance requires tomographic data acquisition during the whole intervention. However, the method, which is also called tomographic fluoroscopy or CT fluoroscopy, will be routinely accepted if the patient dose level can be kept as low as in 2D+time fluoroscopic guidance, which is the standard image guidance techni...
Technical Report
