Diagnostic Imaging

BD-09: Developing a procedure for the manufacture of superconductive contacts for new magnetic resonance imaging scanners

The MRI systems currently in use contain around 1 000 liters of liquid helium to cool the superconductive magnets. If cooling were possible with significantly less helium, there would be no need for the pressure vessel. The systems' inner bore could be larger, bringing benefits to both patients and staff. This goal can be achieved by using magnet wires with the new superconductive material MgB2. It works at much higher temperatures than conventional superconductors, thus making cooling easier.

BD-07: Open and quiet MR tomographs by new coil and gradient technology

This project deals with two issues relating to MR tomography which the patient views as bothersome. In current MR systems, MR signals are received by small local coils. Placing these local coils and keeping them in position takes time and is unpleasant for the patient. Development of an RBA (remote body array) will make local coils unnecessary for many examinations.

The second point is that the gradients induce magnetic eddy currents in the MRT magnetic system during an MR measurement; these are very noisy for the patient.

BD-04: Integrated Breastcare

With its seven sub-projects, the Leading Edge Cluster's "Integrated Breast Care" project covers most of the research spectrum in the field of breast cancer diagnostics. The state-of-the art in breast cancer diagnostics is currently being advanced in the field of in-vitro diagnostics, MR, MR PET, tomosynthesis and ultrasound scans as well as in the field of CAD. A study has been initiated within the framework of this project in which the patient has the opportunity of benefiting from all these diagnostic procedures.

BD-03: High-performance X-ray tube assembly 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

BD-01: Breast-CT

The primary aim of this project is to improve early-stage diagnostics for breast cancer. The goal is to develop a 3D breast X-ray computer tomograph (breast CT for short) for the female breast, characterized by higher sensitivity in the early detection of breast cancer, as well as by greater patient comfort. Every step from the imaging of microcalcifications and the differential diagnosis of lesions with dynamic CT, through to image-guided biopsy can all be performed on one device during just one patient appointment.

Better detection and differentiation between benign and malignant tumors

BD-05: 3D catheter localization for ablation in the heart by means of biplanar fluoroscopy

Atrial fibrillation is the most common form of cardiac arrhythmia, with around one million sufferers in Germany alone. This specific form of cardiac arrhythmia is associated with an increased risk of strokes, the development of cardiac insufficiency as well as general cardiovascular morbidity.

X-ray-guided catheter ablation represents an effective approach to treating atrial fibrillation. With this process, a three-dimensional superimposed image can be calculated from a pre-operative dataset (e.g.

BD-02: CT Angiography for the early detection of coronary heart disease

The major aim of sub-project BD02 is to develop and validate new computer tomography procedures which enable representation of the coronary arteries and the detection and quantification of atherosclerotic plaque with enhanced spatial and temporal resolution, higher reproducibility and, very importantly, with less radiation exposure. Siemens AG is undertaking the technical development work, which includes new detector technologies, new image reconstruction processes and new algorithms for software-based automatic diagnostics.

BD-10: Improving the absolute accuracy of medical positioning devices

Developing a camera-based positioning system that increases the (absolute) positioning accuracy of a patient positioning system (with 6 degrees of freedom) so that the deviation between the actual and target positions is < 0.25mm radius of curvature.

BD-06: Local tumor therapy with magnetic nanoparticles

In 2006, there were 426,800 new cases of cancer in Germany and 210,930 people died of the disease.

About half of all newly diagnosed cancer cases are diagnosed when they are localized to one part of the body. Three quarters of these patients can therefore be cured by local intervention, i.e. by an operation, in some cases supplemented by radiotherapy and/or systemic chemotherapy, with additional antibody therapy where appropriate. However, with the other half of newly diagnosed cases, the illness is already at an advanced stage and will not respond to conventional local therapy.

Localized,
