Classification: CPC G  A | IPC A  G

Claim 13:
14. A non-transitory computer-readable storage medium that stores a radiographic image processing program that causes a computer to perform:
a procedure of acquiring a confirmation radiographic image T0(x, y) including a surgical tool, wherein the confirmation radiographic image T0(x, y) is obtained by combining a radiographic image G0 including a human body and a surgical tool image M0 which indicates the surgical tool by equation (1) using a weight coefficient w1, which is a combination of parameters corresponding to characteristics of at least one of the radiographic image or the surgical tool, wherein the (x, y) is the pixel of the radiographic image G0 where the surgical tool image is combined, and wherein the weight coefficient w1 is set so as to increase as radiation absorptivity of the surgical tool is higher, and is set so as to decrease as an average value of a density of a subject region included in the radiographic image is lower; and
a procedure of detecting a region of the surgical tool from the confirmation radiographic image using a trained model that detects the region of the surgical tool in a target radiographic image in a case that the region of the surgical tool is included in the target radiographic image:

T0(x, y)=G0(x, y)−w1·M0(x, y)   (1).
