  • Publication number: 20070086640
    Abstract: A method for automatically segmenting lung regions in a chest radiographic image comprising; providing an input digital chest radiograph image; preprocessing the input digital radiographic image; extracting the chest body midline and lung centerlines from the preprocessed image. Locating one-by-one, the chest body model, the spine model and the two lung models in the image based on the extracted chest body midline and two lung centerlines; and detecting the lung contours by deforming the lung shape models to converge to the true lung boundaries as a function of the extracting and locating image processing.

  • Publication number: 20050104018
    Abstract: Apparatus for acquiring an elongated radiographic image. The apparatus includes a flat panel electronic detector of radiographic images, the detector having a known length; and a transport mechanism for mounting the detector for movement in a direction parallel to the known length so that the detector can be positioned in sequential contiguous partially-overlapping positions to acquire a radiation image greater in length than the detector length. At least one marker is disposed in a region corresponding with each partially-overlapping position of the detector.
