PROBLEM TO BE SOLVED: To make the best use of good characteristics of a transmission image and to compensate bad characteristics of the transmission image by providing a composing means which puts 1st transmission image data by addition averaging and a 2nd transmission image by a maximum or minimum value projecting method together in one frame. SOLUTION: A multiplier 19 for a transmission image multiplies transmission image data by a weighting coefficient supplied from a weighting coefficient storage unit 21. MIP transmission image data is multiplied by a weighting coefficient supplied from a weighting coefficient storage unit 31 for an MIP transmission image. Then a computing element 23 puts transmission image data from the multiplier 19 for the transmission image and the MIP transmission image data from the multiplier 29 for the MIP transmission image together between frames to generate composite image data. Thus, the 1st transmission image data by addition averaging and the 2nd transmission image data by the maximum or minimum value projecting method are put together in one frame. |
