| Popis: | The aim of this work was to implement the DICOM Grayscale Standard Display Function (GSDF) at all stages of image presentation for computed radiography (CR) and direct digital radiography (DR) modalities. Cathode-ray tubes (CRT) were calibrated according to vendor procedures. Printer look-up-tables (LUT) were measured. Custom LUTs were created and loaded. Fuji CR gradation processing parameters were adjusted to accommodate a GSDF printer LUT. Conformance to the GSDF for hard-copy and soft-copy displays was measured with DICOM Part 14 procedures. One system was intended to completely incorporate the GSDF, although the hard-copy result was correct. The CR systems required creation of custom GSDF printer LUTs, adjustment of gradation processing parameters, and/or calibration of CRT luminance response at the quality control station. The picture archiving and communication system workstations from one vendor required third-party software for calibration. Current implementations of DICOM GSDF by vendors may be inconsistent or nonexistent. Significant effort by in-house staff must be expended to properly incorporate the GSDF. |
