WebNov 10, 2024 · The process of creating a model of an object based on several measured data-sets is usually called a tomographic reconstruction. After reconstructing an object by use of a classical simple reconstruction method, such as filtered back-projection, the object is often segmented by using a computationally demanding segmentation method.
