Automatic tool alignment in a backscatter X-ray scanning system
| DWPI Title: Method for aiming e.g. laser, at portion of concealed target to be imaged using backscatter radiography, involves generating signal that causes angle motor to position tool such that directional axis of tool is coincident with vector |
| Abstract: 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. |
| Use: Method for aiming a medical device such as source of electromagnetic radiation, laser and scalpelat, at a portion of a concealed target to be imaged using backscatter radiography to view a non-uniformly composed material such as human body, for automatic tool alignment in a backscatter X-ray scanning system. |
| Advantage: The method enables allowing a user for selecting the pixel and a computer-executable application to be configured to analyze the image and automatically selecting the pixel. The method enables allowing the tool to be placed on a frame and the motor causing the position/configuration of the frame to change, thus changing the position of the tool in a three-dimensional coordinate system. |
| Novelty: The method involves receiving a selection of a pixel in an X-ray image (122) of a concealed target, where the x-ray image is generated by a backscatter X-ray scanning system (102), and location of the pixel in the X-ray image corresponds to an output vector (110), where an X-ray source (108) in the backscatter x-ray scanning system transmits collimated X-rays. A signal causing an angle motor (132) is generated to position a tool (128) such that a directional axis (130) of the tool is coincident with the vector in response to receiving the selection of the pixel in the X-ray image. |
