Detecting motion by using a low dose x-ray image

Abstract:

A reference image of a patient may be generated. A subsequent x-ray image of the patient may be generated after the generating of the reference image where the subsequent x-ray image is associated with a low dosage. A difference between the reference image and the subsequent x-ray image that is associated with the low dosage may be determined. A motion of the patient may be identified as having occurred based on the determined difference.
