    摘要: A method for image quality assessment of a digital radiography system extracts and isolates one or more individual targets from a phantom image, then obtains operator responses by displaying each isolated individual target and recording a corresponding operator response related to image appearance for each isolated individual target. The accumulated operator responses are stored to obtain the image quality assessment.

    摘要: A method for automatically modifying the rendering of an image based on an analysis of pixel values within a selected region of interest. The method includes: providing a digital input image of digital pixel values and tone scale look-up table (LUT); creating a default rendered image by applying the tone scale lookup table to the input image; displaying the default rendered image; selecting a region of interest from the input image; computing the histogram of the pixel values within the region of interest; creating a bright light image by remapping the pixel values within the region of interest based on an analysis of the histogram and the tone scale table.

    摘要: An apparatus for capturing information associated with an x-ray image recordable on an x-ray imaging plate. The apparatus is configured to be held in a hand of a user of the apparatus and includes a receiving area, a display, a replaceable rechargeable power supply, one or more non-image sensors, and a computer system. The receiving area receives the x-ray image plate or attaches the apparatus to the x-ray imaging plate. The non-image sensors collect information associated with the x-ray image recorded on the x-ray imaging plate. The computer system includes memory, and is configured to receive, measure, store, and subsequently communicate to another computer system, the collected information associated with the x-ray image recorded on the x-ray imaging plate.

    摘要: A radiation imaging system includes a radiation head with a radiation source and an adjustable angular orientation. A radiation image detection device has a photostimulable medium that records an image according to radiation emitted from the radiation source. A measurement sensor apparatus, preferably inertial, is coupled sequentially to the photostimulable medium to provide three-dimensional data for determining the angular orientation of the photostimulable medium and to the radiation source for determining its angular orientation. There is at least one indicator responsive to the orientation data from the measurement sensor apparatus for indicating an orientation adjustment of the radiation source is needed in at least one direction.

    摘要: A computerized method to aid in human visual reading of phantom image data for task-based image quality assessment. A digital image is registered to a phantom template to generate a plurality of individual targets. The individual targets are sequentially displayed to a user for visual assessment. A display control adjustment is provided for each of the displayed individual targets. The user then indicates at least one assessment of the displayed individual target, and the assessments for all the plurality of targets is stored for analysis. In one arrangement, the individual targets are randomly rotated prior to being sequentially displayed.

    摘要: A method of generating a pulmonary nodule image from a chest radiograph. The method includes the steps of: producing a map of a clear lung field; removing low frequency variation from the clear lung field to generate a level image; and performing at least one grayscale morphological operation on the level image to generate a nodule-bone image. Pulmonary nodules can be detected using the nodule-bone image by the further steps of: pulmonary nodules from a chest radiograph. The method includes the steps of: identifying candidate nodule locations in the nodule-bone image; segmenting a region around each candidate nodule location in the nodule-bone image; and using the features of the segmented region to determine if a candidate is a nodule.
