Consider showing Differential DVHs in addition to Cumulative DVHs #2

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Currently only cDVHs are shown. DICOM RT DVH has a the capability to store 
dDVHs so 
dicompyler should be able to support them as well.

Additionally, it should be possible to switch between cDVH and dDVH 
representation 
regardless of the original DVH data.

I've been looking into cDVH <-> dDVH conversion. The problem with producing 
dDVH's is
that they are pure histograms, whose visual presentation and thus interpretation
depends greatly on the bin width. There is apparently a whole body of theory 
behind
optimal bin width selection...

E.g. http://www.ton.scphys.kyoto-u.ac.jp/~hideaki/res/histogram.html

Obviously this is handled satisfactorily by other TPS software, so I'm sure we 
will
figure out something.
