Publication number: 20230010730Abstract: Described herein are examples of industrial radiography systems that enable rotation of a part about a custom axis that is offset from an actual rotation axis of a rotatable fixture that retains the part. This may be valuable in situations where it is difficult, impractical, and/or impossible to align the center of the part with the center of the rotatable fixture. In some examples, the custom axis rotation may be implemented on existing radiography machines, without requiring physical alteration of the radiography machines, integration of new components into the radiography machines, and/or risk of instability to the part and/or radiography machines.Type: ApplicationFiled: July 8, 2021Publication date: January 12, 2023Inventors: Joseph Schlecht, Caleb Nelson Hay, Eric Ferley

Publication number: 20210172886Abstract: Techniques are disclosed for identifying and reducing pixel-specific image distortion of an x-ray detector. In one example, an x-ray detector obtains, for various calibration positions, two-dimensional (2D) images of a calibration object. The calibration object comprises reference points that comprise spatial characteristics. Processing circuitry computes an image distortion field across a plurality of pixels of the x-ray detector based on imaged characteristics of the reference points in each of the 2D images, the spatial characteristics of the reference points, and the calibration positions. The processing circuitry computes, based on the computed image distortion field, a correction transform for correcting image distortion across the x-ray detector. The processing circuitry applies the correction field to a preliminary image obtained by the x-ray detector to obtain a corrected image exhibiting reduced pixel-specific image distortion.Type: ApplicationFiled: November 17, 2020Publication date: June 10, 2021Inventors: Michael Glatzmaier, Joseph Schlecht, Eric Ferley

Patent number: 10413259Abstract: An imaging system generates a first radiograph based on a first pattern of radiation detected by a Linear Diode Array (LDA) radiation detector positioned to detect a radiation beam emitted by a radiation generator. The LDA radiation detector comprises a plurality of modules. Each respective module of the plurality of modules comprises a respective plurality of photodiodes corresponding to pixels. Furthermore, the imaging system may determine, based on the first radiograph, a size of a gap between two of the modules of the LDA radiation detector. After determining the size of the gap, the imaging system may generate a second radiograph based on a second pattern of radiation detected by the LDA radiation detector. The imaging system may generate a third radiograph by modifying, based on the size of the gap, the second radiograph to compensate for the gap.Type: GrantFiled: January 10, 2016Date of Patent: September 17, 2019Assignee: Illinois Tool Works Inc.Inventors: Joseph Schlecht, Eric Ferley, Julien Noel, Roland Le Floc'h

Patent number: 9459217Abstract: An x-ray imaging system (10), such as a X-ray computerized tomographic system, may acquire a series of radiographs at different detector positions along a first translation axis or a second translation axis parallel to orientation directions of detector pixels of a radiation detector (14). In a first embodiment, the different detector positions may be separated by a distance less than a linear size of the radiation detector (14) along the first translation axis or the second translation axis, respectively. The radiographs may be assembled into a radiograph larger than each radiograph in the series of radiographs, resulting in image stitching. In a second embodiment, the different detector positions may be separated by a distance less than a pixel size of the radiation detector (14), also referred as sub-pixel shifting of the detector. The radiographs may be assembled to form a radiograph with a higher resolution than the acquired radiographs, resulting in superresolution.Type: GrantFiled: April 2, 2014Date of Patent: October 4, 2016Assignee: Illinois Tool Works, Inc.Inventors: Yuxin Wang, Joshua A.
