LUNG SEGMENTATION AND BONE SUPPRESSION TECHNIQUES FOR RADIOGRAPHIC IMAGES

摘要

Lung segmentation and bone suppression techniques are helpful pre-processing steps prior to radiographic analyses of the human thorax, as may occur during cancer screenings and other medical examinations. Autonomous lung segmentation may remove spurious boundary pixels from a radiographic image, as well as identify and refine lung boundaries. Thereafter, autonomous bone suppression may identify clavicle, posterior rib, and anterior rib bones using various image processing techniques, including warping and edge detection. The identified clavicle, posterior rib, and anterior rib bones may then be suppressed from the radiographic image to yield a segmented, bone suppressed radiographic image.

主权项

1. A method for performing lung segmentation, the method comprising:
receiving, by a processor, a radiographic image; identifying, by the processor, region of interest (ROI) boundaries within the radiographic image; identifying, by the processor, lung boundaries in accordance with the ROI boundaries; and merging, by the processor, the lung boundaries to generate a segmented lung structure.
