5. An X-ray image processing system comprising:
a storage configured to store X-ray image data;
a display device configured to display an X-ray image; and
at least one hardware image processor which executes:
an input unit configured to receive a user input through a user interface; and
a control unit configured to process the X-ray image data for obtaining the X-ray image to be displayed according to the user input and display the X-ray image on the display device,
wherein the X-ray image is a panoramic image based on Computed Tomography (CT) image data,
wherein the input unit receives a part of an object from the panoramic image, and
wherein the control unit calculates an actual three-dimensional (3D) length of the part of the object based on depth map including a depth information of the panoramic image using the CT image data and displays, on the display device, the actual 3D length in a cross-sectional image of the part of the object in a depth direction or a cross-sectional image in a plane capable of displaying a full length of the part of the object in the depth direction,
wherein the depth map including the depth information is created for respective positions of the panoramic image for calculating the actual 3D length of the part of the object.
6. The X-ray image processing system of claim 5 ,
wherein the input unit receives a first length measurement line on the part of the object, and
wherein the control unit is configured to display a second length measurement line of the actual 3D length on the part of the object in the cross-sectional image.
7. The X-ray image processing system of claim 6 ,
wherein the user input unit receives at least one of an adjusted position, an adjusted direction, and an adjusted length of the second length measurement line.
8. The X-ray image processing system of claim 5 , wherein the cross-sectional image includes at least one of a coronal cross-sectional image, a sagittal cross-sectional image, and an axial cross-sectional image.
9. An X-ray image processing system comprising:
