Different imaging techniques provide unique information; for instance, MRI reveals soft tissue details, while CT scans offer better images of bone structures. Combining these images offers a comprehensive view of anatomy and pathology. By overlaying images from different modalities, physicians can better understand the location, extent, and nature of a disease, leading to more accurate diagnoses. To achieve this, multi-modal image registration is essential. Accurate registration helps planning surgeries, radiation therapy, and other treatments. Additionally, registering images taken at different times or with different modalities allows for precise monitoring of disease progression or response to treatment.
