PROBLEM TO BE SOLVED: To provide an X-ray CT apparatus capable of calculating a smoothing coefficient at a high speed.SOLUTION: An operation apparatus 202 calculates the smoothing coefficient related to a first coefficient calculation range (prestage range) by a repeating technique using a preliminarily defined initial value (S 301). Next, the operation apparatus 202 sets the initial value used in the smoothing coefficient calculating processing related to a target range to the smoothing coefficient related to the first coefficient calculation range (S 302) and calculates the smoothing coefficient related to a second coefficient calculation range (target range) by the repeating technique (S 303). |
