ADC DICOM Images

ADC (ADC70, Compact, Compact plus, Solo) can output images via the processing station QS using the DICOM CR Storage Service Class. Several configurable image formats are possible, created to achieve maximum operability with Agfa and OEM PACS systems or workstations. The images downloadable at this site are in the most used formats:

• A.12 bit DICOM image scaled to Relative Log Exposure
• B.12 bit DICOM image scaled to Absolute Optical Density

If there are image quality issues while displaying these images please contact System Integration & Validation (SIV) / Connectivity group (see below) for more details.

Image format A. contains the full, 12-bit scanned (MUSICA processed) data. The sensitometric user (taste) LUT, as selected on the QS (e.g. E25, RP1KT), is sent along with the DICOM stream by means of a sequenced VOI LUT. This DICOM image format is used for Agfa QS to IMPAX connections, as it transfers full scanned data with associated LUT information. Other vendors can also use it. However, it does require implementation of the DICOM VOI LUT module, in order to interpret the LUT data. The image is unified to Relative Log Exposure, since the scanned data is directly proportional to the logarithmic unit to exposure on the imaging plate.

Image format B. contains 12-bit post-processed data scaled to Optical Densities. After the QS has found the relevant portion of the scanned data, it will apply MUSICA as well as the sensitometric user (taste) LUT. The resulting 12-bit post-processed data will be sent along with a linear DICOM Modality and VOI LUT. The receiving network or workstation is expected to apply the information in the Modality and VOI LUT. In this way, the actual image will be unified to absolute Optical Densities between 0.2 and 3.0 OD. Note that the Window (2800) and Level (1600) values are given in (thousands of) Optical Densities.
