X-ray imaging apparatus and X-ray imaging system
An X-ray imaging apparatus displays a bone or soft tissue image of an X-ray image, which corresponds to a region selected by a user, thereby reducing a diagnosis time. In addition, an X-ray imaging system transmits a first energy X-ray image and a second energy X-ray image to a central image management system, and a user control apparatus receives the images from the central image management system and displays a bone or soft tissue image corresponding to the selected region, thereby reducing burden imposed on server capacity of the central image management system as well as reducing a diagnosis time.
1. An X-ray imaging apparatus comprising:
an X-ray generator configured to generate X-rays and to irradiate an object with the X-rays;
an X-ray detector configured to detect the X-rays including high energy X-rays and low energy X-rays irradiated from the X-ray generator and transmitted through the object; and
a host device configured to:
generate a high energy X-ray image and a low energy X-ray image from the detected X-rays and display at least one of the high energy X-ray image and the low energy X-ray image,
after a region of the displayed X-ray image is selected by a user, extract at least one image information using the high energy X-ray image and the low energy X-ray image corresponding to the region selected by the user, and
display an image containing the extracted at least one image information.
2. The X-ray imaging apparatus according to claim 1 , wherein the X-ray detector is further configured to separate the high energy X-rays and the low energy X-rays.
3. The X-ray imaging apparatus according to claim 1 , wherein the host device is configured to extract a bone image and a soft tissue image using the high energy X-ray image and the low energy X-ray image.
4. The X-ray imaging apparatus of claim 1 , wherein the X-ray detector comprises a photon-counting detector configured to divide the detected X-rays according to energy levels.
5. The X-ray imaging apparatus of claim 4 , wherein the photon-counting detector is further configured to compare the detected X-rays to a reference voltage to output a plurality of pulses.
6. The X-ray imaging apparatus of claim 5 , wherein the photon-counting detector is further configured to count the plurality of pulses to determine an intensity of the detected X-rays.
7. An apparatus comprising:
a display configured to display at least one X-ray image from among a high energy X-ray image of an object and a low energy X-ray image of the object; and
a controller configured to receive a selection of a region of the displayed at least one X-ray image from a user, to extract at least one image information, corresponding to the region selected by the user, using the high energy X-ray image and the low energy X-ray image, and to control the display to display an image containing the extracted image information.
8. The apparatus of claim 7 , wherein the controller is configured to control the display to display the at least one X-ray image in a first region of the display, and to display the image containing the extracted information in a second region of the display.
