The curve is drawn on the
canvas of the main window,
while data are reported into a
separated window, from which
you can edit them. This window
is always "on the top" and you
can move it to discover parts of
the graphic below, but if you
close it, the graphic disappears
too. The graphic reports three
curves in different colors and
symbols. The radiation curve for
the Molibdenum/Molibdenum
target/filter is drawn in cyan, for
the Molibdenum/Rhodium
target/filter is drawn in solid
yellow and for the
Tungsten/Rhodium target/filter in
dotted red. A little legend helps
identifying the curves. The title of
the graph also reports the values
of Dose Rate and Tube Output.
Data are presented in a "kV" versus reference dose grid. Any row correspond to a
point of the curve. The kV steps are fixed, so this column is unselectable. Data
are shown (and accepted) in µGy or mR, depending on the radiobutton selected
in the "Radiation unit" radiogroup, and for 1mAs or 50mAs as selected in the
corresponding radiogroup, while the graph is always constructed with µGy for
1mAs. To view and edit data for a target/filter combination just click on the
corresponding tab. The radiation unit and mAs are separately selectable for each
target/filter.
Doubleclicking a row, a "New value"
dialog pops-up, indicating the
radiation unit, mAs, distance and kV
for which a new value is requested,
and showing the actual value. Just
type the desired new value and
press OK. The dialog closes and
the entered number overwrites the
old one. The curve is redrawn,
representing immediately the
correction made.
