The book explores advancements in diagnostic radiology, particularly focusing on computerized tomography (CT) and its ability to reconstruct density distributions within the human body from multiple x-ray projections. It highlights the necessity for numerous projections to achieve accurate reconstructions, especially in scenarios where objects have limited density values, such as in industrial CT or specific medical applications like angiography. The text also discusses the application of electron microscopy in reconstructing biological macromolecules and crystalline structures based on similar binary value assumptions.
