What is a medical image reconstruction algorithm?

A medical image reconstruction algorithm is a computational method used to generate visual images from raw data collected by medical imaging devices, such as CT, MRI, or PET scanners. These algorithms process signals or projections to create detailed images of the inside of the human body, which are essential for diagnosis and treatment planning. They use advanced mathematics and computer science techniques to improve image quality, reduce noise, and enable faster image acquisition. Advances in reconstruction algorithms have significantly improved the accuracy and speed of medical imaging, leading to better patient outcomes.
