Image Reconstruction is a process used to create a visual representation from raw data, often in fields like medical imaging and computer vision. It involves algorithms that convert incomplete or noisy data into a clearer image, allowing for better analysis and interpretation. In medical applications, such as MRI or CT scans, image reconstruction helps doctors visualize internal structures of the body. By enhancing the quality of the images, it aids in accurate diagnosis and treatment planning, making it a crucial tool in modern healthcare.
