摘要: Spatial absorption density distributions are reconstructed from simulated sequential transmission scans at multiple angles utilizing computer approximation techniques. A quantitative measure of the relative variance map is obtained, and component due to Poisson statistics shown be in agreement with a theoretically derived function.
