Image reconstruction is a process used to create a visual representation from raw data, often in fields like medical imaging and photography. It involves algorithms that analyze the data collected from various sources, such as CT scans or MRI, to produce a clear and detailed image. This technique is essential for improving image quality and accuracy, allowing for better diagnosis and analysis. By reconstructing images, professionals can visualize complex structures, making it easier to identify issues or abnormalities in areas like healthcare and remote sensing.
