1. A medical imaging apparatus comprising:
- an X-ray emitter configured to emit first X-rays and second X-rays toward an object;
an X-ray detector configured to detect the first X-rays and the second X-rays that have been emitted to obtain a first X-ray image and a second X-ray image, corresponding to a plurality of areas of the object;
a processor, which is configured to obtain information about a first detector location for obtaining the first X-ray image and information about a second detector location, wherein the X-ray detector moves from the first detector location, for obtaining the second X-ray image, is configured to generate a first virtual ruler based on a first distance from a reference point to the first detector location and a second virtual ruler based on a second distance from the reference point to the second detector location, and is configured to obtain a composite image by combining the first X-ray image and the second X-ray image based on the first virtual ruler and the second virtual ruler; and
a display configured to display the composite image on which the first virtual ruler and the second virtual ruler are displayed,wherein, when a user input for moving the first X-ray image of the composite image along a first direction is received, the processor moves the first X-ray image along the first direction without moving the first virtual ruler, andthe display is configured to display the first virtual ruler and the second virtual ruler on the composite image by aligning the first virtual ruler and the second virtual ruler as a one-dimensional ruler in correspondence to the first image and the second image.

10. A method of displaying a medical image, the method comprising:
-
emitting first X-rays and second X-rays toward an object; detecting the first X-rays and the second X-rays that have been emitted to obtain a first X-ray image and a second X-ray image, corresponding to a plurality of areas of the object; obtaining information about a first detector location for obtaining the first X-ray image and information about a second detector location, wherein the X-ray detector moves from the first detector location, for obtaining the second X-ray image; generating a first virtual ruler based on a first distance from a reference point to the first detector location and a second virtual ruler based on a second distance from the reference point to the second detector location; obtaining a composite image by combining the first X-ray image and the second X-ray image based on the first virtual ruler and the second virtual ruler; displaying the composite image on which the first virtual ruler and the second virtual ruler are displayed, and moving the first X-ray image of the composite image along a first direction without moving the first virtual ruler when a user input for moving the first X-ray image along the first direction is received, wherein the displaying comprises displaying the first virtual ruler and the second virtual ruler on the composite image by aligning the first virtual ruler and the second virtual ruler as a one-dimensional ruler in correspondence to the first image and the second image.

11. A medical imaging apparatus comprising:
-
an X-ray emitter configured to emit first X-rays and second X-rays toward an object; an X-ray detector configured to detect, in a first imaging area, the first X-rays, and to detect, in a second imaging area, the second X-rays, the first X-rays and the second X-rays having been emitted to obtain a first X-ray image and a second X-ray image, corresponding to a plurality of areas of the object; a processor, which is configured to obtain information about a first location of the X-ray detector for obtaining the first X-ray image and information about a second location to which the X-ray detector moves from the first location, for obtaining the second X-ray image, is configured to generate a first virtual ruler based on a first distance from a reference point to each of sides of the first imaging area of the X-ray detector positioned at the first location and a second virtual ruler based on a second distance from the reference point to each of sides of the second imaging area of the X-ray detector positioned at the second location, and is configured to obtain a composite image by combining the first X-ray image and the second X-ray image based on the first virtual ruler and the second virtual ruler; and a display configured to display the composite image, and is further configured to display the first virtual ruler and the second virtual ruler on the composite image by aligning the first virtual ruler and the second virtual ruler as a one-dimensional ruler in correspondence to the first image and the second image.
