Abstract:
1. A method comprising: detecting for electromagnetic interference (EMI); prompting a user to perform electromagnetic shielding of a portable x-ray detector when an EMI above a predetermined limit is detected, wherein electromagnetic shielding comprises magnetically shielding the portable x-ray detector by creating a closed magnetic path around the portable x-ray detector to redirect an impinging magnetic field through the closed magnetic path; and prompting the user that EMI above the predetermined limit is not present when EMI less than or equal to the predetermined limit is detected; generating a first dark image at an imaging location; comparing the first dark image to a second dark image, wherein the second dark image was generated from the portable x-ray detector positioned in a known EMI free location; and determining if EMI above the predetermined limit is present based on the comparison.
