Challenge

The increasing frequency of CT examinations leads to higher radiation exposure across the population. Furthermore, the presence of metallic implants creates significant issues, such as beam starvation and streaks, which can compromise image quality and render images non-evaluable.

Scientific Approach

Modified imaging techniques combined with spectral CT are being developed to improve diagnostic quality while simultaneously reducing radiation exposure. Key objectives include improving the signal-to-noise ratio for better tissue differentiation, reducing metal-induced artefacts, and investigating ways to reduce the need for contrast agents.

Objectives and Impact

This project aims to improve diagnostics and therapy for a wider range of patients while minimising radiation exposure. The methods developed to reduce metal artefacts will also be directly applied to the development of anthropomorphic test specimens with neuromodulation electrodes.
