Abstract
This X-ray imaging apparatus is equipped with an image processing unit. The image processing unit obtains a first image with a marker reference position set in a first X-ray image and generate a second image in which a virtual marker image is superimposed at a corresponding position in a second X-ray image reflecting the change of a relative position from the marker reference position with respect to the second X-ray image different from the first X-ray image.
Claims22
An X-ray imaging apparatus comprising:
- an imaging device that captures an X-ray image by irradiating X-rays to a subject and detecting the X-rays that have passed through the subject;
- a reference position setter that sets a marker reference position with respect to a first X-ray image;
- a marker generator that generates a first image in which a virtual marker image is superimposed at the marker reference position in the first X-ray image;
- a display that displays the first image;
- and
- a relative position calculator that resets the marker reference position to a position reflecting a change of a relative position between the subject and the imaging device with respect to a second X-ray image captured in which the relative position is changed,
- wherein the relative position calculator resets the marker reference position after displaying the first image,
- wherein the marker generator generates a second image in which the virtual marker image is superimposed again at the reset marker reference position, and
- wherein the second image is displayed on the display.
An X-ray image display method configured to capture an X-ray image by irradiating X-rays to a subject and detecting the X-rays that have passed through the subject, process the captured X-ray image, and display the X-ray image, the method comprising:
- setting a marker reference position with respect to a first X-ray image;
- generating a first image in which a virtual marker image is superimposed at the marker reference position in the first X-ray image;
- displaying the first image;
- resetting the marker reference position to a position reflecting a change of a relative position between the subject and the imaging device with respect to a second X-ray image captured in which the relative position is changed after displaying the first image;
- generating a second image in which the virtual marker image is superimposed again at the reset marker reference position;
- and
- displaying the second image.
