Abstract
A method for image correction in a mobile X-ray device includes obtaining an X-ray image corresponding to a region of interest, where the X-ray image includes a projection of the region of interest by an X-ray beam on a detector plane. The method further includes receiving a tilt parameter corresponding to the detector plane. Moreover, the method includes generating a corrected X-ray image based on the X-ray image and the tilt parameter using a perspective projection technique, where the corrected X-ray image corresponds to a projection of the region of interest on a corrected detector plane.
Claims22
A method for image correction in a mobile X-ray device, the method comprising:
- obtaining an X-ray image corresponding to a region of interest, wherein the X-ray image comprises a projection of the region of interest by an X-ray beam on a detector plane;
- receiving a tilt parameter corresponding to the detector plane;
- and
- generating a corrected X-ray image based on the X-ray image and the tilt parameter using a perspective projection technique, wherein the corrected X-ray image corresponds to a projection of the region of interest on a corrected detector plane.
A mobile X-ray device, comprising:
- an image acquisition unit comprising at least an X-ray source and an X-ray detector, wherein the image acquisition unit is configured to obtain an X-ray image corresponding to a region of interest, and wherein the X-ray image comprises a projection of the region of interest by an X-ray beam on a detector plane;
- a detector tilt correction unit communicatively coupled to the image acquisition unit and configured to:
- receive a tilt parameter corresponding to the detector plane;
- and
- generate a corrected X-ray image based on the X-ray image and the tilt parameter using a perspective projection technique, wherein the corrected X-ray image corresponds to a projection of the region of interest in a corrected detector plane.
A non-transitory computer readable medium comprising one or more tangible media, wherein the one or more tangible media comprise code for causing a computer to perform the steps of:
- obtaining an X-ray image corresponding to a region of interest in a subject, wherein the X-ray image comprises a projection of the region of interest by an X-ray beam on a detector plane;
- receiving a tilt parameter corresponding to the detector plane;
- and
- generating a corrected X-ray image based on the X-ray image and the tilt parameter using a perspective projection technique, wherein the corrected X-ray image corresponds to a projection of the region of interest in a corrected plane.
