Stefan Kaczmarz [SEP] date of birth
Stefan Kaczmarz
Stefan Kaczmarz (born 1895 in historic Polish town Sambor, Galicia, Austria-Hungary (now Ukraine) – 1939) was a Polish mathematician. His Kaczmarz method provided the basis for many modern imaging technologies, including the CAT scan.
Kaczmarz was a professor of mathematics in the faculty of mechanical engineering of Jan Kazimierz University of Lwów from 1919 to 1939, where he collaborated with Stefan Banach.
The circumstances of Kaczmarz's death are unclear. In early September 1939, he was called up for military
Kaczmarz method
The Kaczmarz method or Kaczmarz's algorithm is an iterative algorithm for solving linear equation systems formula_1. It was first discovered by the Polish mathematician Stefan Kaczmarz, and was rediscovered in the field of image reconstruction from projections by Richard Gordon, Robert Bender, and Gabor Herman in 1970, where it is called the Algebraic Reconstruction Technique (ART). ART includes the positivity constraint, making it nonlinear.
The Kaczmarz method is applicable to any linear system of equations, but its computational advantage relative to other methods depends
