Quality assesment in clinical brain CT
In emergency brain imaging, CT is often the first and most time-sensitive imaging tool for detecting stroke, trauma, or bleeding. Any reduction in image quality, whether caused by motion, metallic implants, or incorrect technical settings, can hinder the visibility of critical findings. If such problems are detected only after the patient has left the scanner, another scan may be necessary. This leads to delays in treatment decisions which is especially problematic when seconds count.
To prevent such scenarios, it is highly desirable to automatically evaluate, document, and report image quality immediately after scan acquisition.
In a related but distinct direction, the widespread adoption of AI-based reconstruction and diagnostic algorithms raises a new challenge: the need to objectively assess the quality of AI-generated results. One promising solution is the development and evaluation of advanced clinical imaging phantoms, which can be used to benchmark system performance and ensure reliable and reproducible outcomes across different CT devices.
