Claim:
1. A radiological image radiographing and displaying system having a radiation emitting unit that irradiates a subject with radiation from different radiographing directions, a radiological image detector that detects the radiation emitted from the radiation emitting unit and passing through the subject, and a display unit that acquires radiological images radiographed in each radiographing direction which is detected by the radiological image detector and that displays a stereoscopic image using the acquired radiological images of the radiographing directions, the system comprising: an input device configured to designate, according to user input, a three-dimensional position in the stereoscopic image when the stereoscopic image is displayed on the display unit; and a computing device configured to acquire three-dimensional position information based on the designation of the three-dimensional position by the input device, wherein the display unit is configured to display the stereoscopic image as a three-dimensional image and each radiological image radiographed in each radiographing direction as two-dimensional images and is configured to display a mark based on the three-dimensional position information acquired by the computing device in each of the two-dimensional images, and wherein the input device is further configured to move the mark according to user input to designate a two-dimensional position in each of the two-dimensional images after the mark is displayed in each of the two-dimensional images, wherein the computing device is further configured to acquire other three-dimensional position information based on the designation of the two-dimensional position by the input device in the case that the input device has designated the two-dimensional position in at least one of the two-dimensional images, such that the three-dimensional position in the stereoscopic image is changed based on the other position information, wherein the display unit includes a monitor and is further configured to display an image on the monitor, the image representing a predetermined threshold range in the two-dimensional images on the basis of coordinates in the depth direction of the position designated in the stereoscopic image, wherein the computing device is configured to calculate the predetermined threshold range, wherein the computing device is configured to calculate the predetermined threshold range depending on a resolution in the depth direction determined on the basis of the distance between the focal point of radiation of the radiation emitting unit and the radiological image detector and a convergence angle formed by the radiographing directions.
