CFIND with InformationModel as MWL and Query parameter as ScheduledProcedureStepStartDate

[harshitha]

Hello All,

I am trying to perform a CFIND Query with Information Model as MWL and query parameter as ScheduledProcedureStepStartDate.

By directly providing <QueryParameters>ScheduledProcedureStepStartDate={some value}</QueryParameters> is not working as, the tag is present inside ScheduledProcedureStepSequence,which is basically a sequence.

So how do we pass such values as query parameters?

ScheduledProcedureStepSequence.ScheduledProcedureStepStartDate=<value>

Hello, Thanks for the response. Tried the same but got an error as follows.

java.lang.IllegalArgumentException: ScheduledProcedureStepSequence.ScheduledProcedureStepStartDate

Which version of dcm4che tools are you using? Fyi : The way sequence attributes are specified in matching / return / set flags in various dcm4che utilities was unified to keep it inline with DICOM web services query parameters syntax in v5.23.1. So, if you're using dcm4che toolkit version older than this one, use ScheduledProcedureStepSequence/ScheduledProcedureStepStartDate instead.

With latest version of toolkit :
