An image processing device comprising: a tomographic image generation means configured to generate a plurality of tomographic images of an imaging subject, which is a site on a human body, by reconstructing a plurality of radiographic images acquired from a radiographic image detection device using a detection face of the radiographic image detection device as a reference, the plurality of radiographic images being acquired by moving a radiation irradiation section facing the radiographic image detection device through a plurality of positions and irradiating the imaging subject disposed on the radiographic image detection device with radiation from each of the plurality of positions such that the radiation is irradiated at different angles with respect to the imaging subject; a first specification means configured to display on a display means at least one tomographic image of the plurality of tomographic images, in which an object of interest in the imaging subject has been captured, and that allows a user to specify a position of the object of interest in the at least one tomographic image based on the display; a second specification means configured to display on the display means at least one of the plurality of tomographic images including a region from the object of interest to a side from which a biopsy needle is to be inserted based on the position of the object of interest and a direction of insertion of the biopsy needle, and allows the user to specify, based on the display, a desired pass-through region of the biopsy needle, a non-pass-through region through which it is undesirable for the biopsy needle to pass, or a combination thereof; a detection means configured to detect a path of the biopsy needle passing through the pass-through region and reaching the object of interest, wherein the desired pass-through region is regarded as the pass-through region if a desired pass-through region has been specified, and a region other than the non-pass-through region is regarded as the pass-through region if a non-pass-through region has been specified; and a warning means configured to issue a warning if the detected path is outside a predetermined movement range of the biopsy needle. a tomographic image generation means configured to generate a plurality of tomographic images of an imaging subject, which is a site on a human body, by reconstructing a plurality of radiographic images acquired from a radiographic image detection device using a detection face of the radiographic image detection device as a reference, the plurality of radiographic images being acquired by moving a radiation irradiation section facing the radiographic image detection device through a plurality of positions and irradiating the imaging subject disposed on the radiographic image detection device with radiation from each of the plurality of positions such that the radiation is irradiated at different angles with respect to the imaging subject; a first specification means configured to display on a display means at least one tomographic image of the plurality of tomographic images, in which an object of interest in the imaging subject has been captured, and that allows a user to specify a position of the object of interest in the at least one tomographic image based on the display; a second specification means configured to display on the display means at least one of the plurality of tomographic images including a region from the object of interest to a side from which a biopsy needle is to be inserted based on the position of the object of interest and a direction of insertion of the biopsy needle, and allows the user to specify, based on the display, a desired pass-through region of the biopsy needle, a non-pass-through region through which it is undesirable for the biopsy needle to pass, or a combination thereof; a detection means configured to detect a path of the biopsy needle passing through the pass-through region and reaching the object of interest, wherein the desired pass-through region is regarded as the pass-through region if a desired pass-through region has been specified, and a region other than the non-pass-through region is regarded as the pass-through region if a non-pass-through region has been specified; and a warning means configured to issue a warning if the detected path is outside a predetermined movement range of the biopsy needle.
