BD-03: High-performance X-ray tube assembly for breast CT

Development of technical fundamentals of a high-performance X-ray system for breast CT

In diagnostic imaging, there is a trend toward three-dimensional spatial resolution imaging: in X-ray technology that means moving away from classical radiography to computer tomography (CT). The Germany Ministry of Education and Research's "Breast CT" project aims to develop a CT system especially for mammography. This CT system will require the X-ray generation system which the Medical Valley project aims to realizes, a system characterized by very small focal spots with very high surface power density and a small mounting space requirement.

The innovative advance compared to current systems presents a real challenge: requirements far in excess of the state-of-the-art will be placed on the power density of the electron beam at the anode, on the components required to deflect the electron beam or the components required for insulation (with very small distances) as well as on the compactness of the high-voltage and generator unit. The first step will be to work out the physical, material-related and electrical basis for this x-ray generation system and then to design a working model to test the breast CT system.
