11 Claims

1. A method of controlling a radiographic image connection apparatus connecting plural partial radiographic images and measuring a distance, said method comprising:

a) an image selection step, performed by a processor, of selecting the plural partial radiographic images;

b) a mode switching step, performed by a processor, of switching between an image position adjustment mode and an image measurement mode;

c) an image connection processing step, performed by a processor, of connecting the selected partial radiographic images, adding markers indicating which parts on the selected partial radiographic images should be matched on the selected partial radiographic images to be connected;

d) an image measurement step, performed by a processor, of measuring a distance in the plural partial radiographic images, in the image measurement mode;

e) a first display control step, performed by a processor, of displaying an object representing the measured distance in the image measurement step and deleting the display of the markers added in the image connection processing step, while in the image measurement mode; and

f) a second display control step, performed by a processor, of displaying the markers and deleting the display of all of the object added in the image measurement mode, except for the object being independently on one of the selected partial radiographic images, and displaying an enlarged connection portion of the selected partial radiographic images and deleting the markers when the markers overlap each other, while in the image position adjustment mode.
