Limitations exist in digital acquisition and display of the most common exam, projection X-ray.
Overall objectives are to design, implement and evaluate digital image processing techniques for softcopy-digital display of projection radiographs using computed radiography chest images. Multiscale image contrast amplification techniques will be investigated. Algorithm design will be optimized for specific chest pathologies and related findings. Statistical analysis of individual observers and pooled data will be performed. Hanging protocols for image display are to be triggered by the database design and the UCSF ViewPort concept.
