AUTOMATIC TOOL ALIGNMENT IN A BACKSCATTER X-RAY SCANNING SYSTEM

摘要

Technologies pertaining to backscatter x-ray scanning systems are described herein. The backscatter x-ray scanning system includes an x-ray source, which directs collimated x-rays along a plurality of output vectors towards a target. A detector detects diffusely reflected x-rays subsequent to respective collimated x-rays impacting the target, and outputs signals indicative of parameters of the detected x-rays. An image processing system generates an x-ray image based upon parameters of the detected x-rays, wherein each pixel in the image corresponds to a respective output vector. A user selects a particular portion of the image, and a medical device is positioned such that its directional axis is coincident with the output vector corresponding to at least one pixel in the portion of the image.

1. A method comprising:
receiving a selection of a pixel in an x-ray image of a concealed target, the x-ray image generated by a backscatter x-ray scanning system, a location of the pixel in the x-ray image corresponding to an output vector over which an x-ray source in the backscatter x-ray scanning system transmits collimated x-rays; and responsive to receiving the selection of the pixel in the x-ray image, generating a signal that causes an angle motor to position a tool such that a directional axis of the tool is coincident with the output vector.
