    摘要: A method is disclosed for acquiring a high speed dual-energy image pair using a pixilated digital detector. A single pixilated digital detector acquires and encodes two separate images in effectively one image, eliminating the need to read out a first image prior to acquiring a second image. The encoded information is then utilized to obtain two distinct dual-energy images which may be decomposed to form bone and soft-tissue only images.

    摘要: A method of forming a composite image from first and second digital images formed by recording first and second contiguous segments of a larger radiographic image in first and second overlapping storage phosphor members, exposed to a source of X-rays wherein the image content in the overlapped region is the same in both images and the end edge of the first member is present both on the first image and as a shadow edge in the second image, the method comprising: correcting for geometric distortion in the first and second digital images; determining any rotational displacement and any vertical displacement between the first and second images by matching the first member end edge in the first image to its shadow in the second image; correcting for image orientation based on any said rotational displacement; determining any horizontal displacement between the first and second images by correlating the image content in the overlapped region of the first and second images; and stitching said first and second images together along the first member end edge based on any said horizontal and vertical displacements.

    摘要: A method for obtaining a radiographic image, the method executed at least in part on a computer, generates a first exposure and acquires image data from the first exposure as a first component image. A second exposure is generated using one or more parameters that are adjusted according to an image quality characteristic of the acquired image data from the first exposure. Image data is acquired from the second exposure as a second component image. One or more additional exposures are generated and an additional component image acquired with each additional exposure. A composite image is formed by combining image data content from the first and second component images and the one or more additional component images.

    摘要: An apparatus for aligning a radiation source with an image receiver has a first light source coupled to the radiation source and actuable to direct a first beam of light toward the image receiver and a second light source coupled to the radiation source and actuable to direct a second beam of light toward the image receiver. A reflector element is coupled to the image receiver and is disposed to form, when placed in the path of both first and second light beams, reflected light that indicates the relative alignment of the image receiver to the radiation source. The reflected light may form a pattern indicative of alignment.
