  • Patent number: 10825855
    Abstract: Bending a flexible x-ray detector to image a curved structure or object will distort the object appearance when compared to an image captured by a flat/rigid detector. An image distortion of this type can be corrected when the shape (relative bend position) of the x-ray detector is known. Incorporating strain sensors on the flexible x-ray detector makes it possible to record the local bend of the flexible x-ray detector when an image is taken. This shape information can be used to either label or correct for the image distortions created by bending the x-ray detector to assist users more accustomed to viewing images produced by flat/rigid x-ray detectors.
