    摘要: A method for longitudinal tracking of a patient in a critical care facility. A first diagnostic image at a time t1 is obtained, taken using a first set of imaging parameters. At least a portion of the first set of imaging parameters is stored. A second diagnostic image is obtained at a time t2, later than time t1, using a second set of imaging parameters. At least a portion of the second set of imaging parameters is stored. First and second diagnostic images are of substantially the same body tissue. A region of interest is identified from either the first or second diagnostic image. A computer aided diagnostic process executes for a portion of the region of interest on each of the first and second diagnostic images. Results of the computer aided diagnostic process are compared.

    摘要: A method for displaying a sequence of fluoroscopic images of a subject defines, within the image area of a digital image receiver and in response to one or more viewer instructions, a region of interest and a background region that lies outside the defined region of interest. A succession of fluoroscopic images is obtained from the digital image receiver and, for image pixels within each of the succession of fluoroscopic images, background region pixel data are encoded and transmitted to the display apparatus using a lossy encoding. Region of interest pixel data is transmitted to the display apparatus using a lossless encoding. The succession of fluoroscopic images is displayed.

    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: A method for 3-D volume image reconstruction of a subject, executed at least in part on a computer, obtains image data for 2-D projection images over a range of scan angles. For each of the plurality of projection images, a noise-corrected projection image is generated by steps of transforming the image data according to a variance-stabilizing transform to provide transformed image data, applying Gaussian based noise suppression to the transformed image data, and inverting the transformation of the noise-suppressed transformed image data to generate the noise-corrected projection image. The noise-corrected projection image is stored in a computer-accessible memory.

A two dimensional radiation image detection device has a receiver that records an image according to radiation emitted from the radiation source, a first sensor coupled in a fixed position relative to the receiver that detects the alignment signal from the emitter and provides a first response signal and a second sensor coupled in a fixed position relative to the receiver that detects the alignment signal from the emitter and provides a second response signal. A control logic processor is in communication with the first and second sensors for receiving the first and second response signals and further in communication with at least one indicator for indicating the alignment of the image detection device relative to the radiation source.
