Summary
New artificial surface markers improve the reproducibility of imaging information transfer across different modalities like MRI, CT, and X-ray. These markers enhance treatment planning by providing consistent reference points without burdening patients.
Area of Science:
- Medical Imaging
- Radiotherapy Planning
- Diagnostic Imaging
Context:
- Accurate transfer of image information between different imaging modalities is crucial for effective treatment planning.
- Anatomical landmarks are traditionally used for referencing, but their consistency can vary.
- Standardization of imaging data across modalities is essential for maximizing diagnostic and therapeutic benefits.
Purpose:
- To improve the reproducibility of image information transfer across various imaging techniques.
- To compare topographic relations, measurements, and positioning using novel marking aids/surface markers.
- To assess the effectiveness of artificial markers in conjunction with anatomical landmarks.
Summary:
- Developed and evaluated artificial marking aids/surface markers visible in MRI, CT, and X-ray imaging.
- These markers, containing iodine-based contrast medium, are fixed to the skin over anatomical reference points.
- A method for integrating these artificial markers with individual anatomical landmarks was introduced, demonstrating consistent visibility and utility.
Impact:
- The artificial markers facilitate the recognition of anatomical relation lines and edges for radiotherapy planning.
- They serve as reliable reference structures for comparing the localization and extent of lesions across X-ray, CT, and MRI.
- The marking aids are versatile and do not require modification for different imaging methods, simplifying workflows.
