Convert Dose to Dose Value

Hello,

I'm looking to convert Dose to Dose Value. More specifically I'm looking to grab the total dose (i.e. the Prescription Dose) of the plan sum. The Plan Sum class has a Dose property which from the documentation looks like it is:

"The total dose. The total dose is the dose of all planned fractions together."

Is the only way to get the "Total Prescription Dose" for a plan sum is to loop through each plan in the plan sum and sum the "TotalPrescribedDoses"?



Thanks,

This question is harder to answer than you might think. Given the different ways that plans can contribute to plansums with RBE scaling factors, etc, one has to be careful when calculating 'total prescription dose'. The answer depends on how your physicians prescribe dose and how you are adding up doses for that particular treatment, which is why you don't find Total Prescription Dose in the PlanSum class.

That makes sense when you look at it from a BED standpoint. With different fraction sizes, it would be dependent on the clinic, the equivalent dose they want to convert to, alpha/beta ratios, etc....

Thanks
