Abstract
In a project of the Ruhr Center of Excellence for Medical Engineering at the Ruhr University Bochum, a system was developed for ultrasound computed tomography of the female breast. A high precision mechanical system was realized to implement a tomography system around a commercial ultrasound scanner. With this setup, ultrasound data was acquired in reflection mode from different aspect angles to spatially compound images of a flow mimicking phantom fed with contrast agent. The resulting compound images of multiple parallel section planes were combined to generate a volume data set, from which the contrast enhanced vessel structures were extracted. With this approach, both general and contrast specific artifacts were reduced and a high resolved subtraction angiography was realized from ultrasound data.
