Using the Graphs Tab
Use the controls on the Graphs tab to select a conformance test and
change how the system shows the data for a selected test. When
using multiple display panels, select a particular panel in the Display
drop-down list. Select a particular conformance test by selecting the
data and time of the test in this drop-down list. Use Print Graph to
output the graph currently on the screen.
Graph Type
• Response. Presents the luminance values at various luminance
intervals (P-values). Luminance is shown along the vertical axis
using a scale that you select from three options: Linear / Lum,
Linear / Log Lum, and Linear / JND Lum. The Response graph
consists of a curve and a set of data points. The curve shows
the luminance values specified by the DICOM standard and the
data points show the luminance values measured during the
conformance test. In general, the closer the data points match the
curve, the better the DICOM conformance.
