Hi,

If I have sample bits like this (explicit VR little endian) :

00 54 0a 10 4f 57 00 00 02 00 00 00 00 80

So, It means :

00 54 0a 10 = tag (5400,100a) : waveform padding value
4f 57 = "OW" (the VR value)
00 00 = 0000h reserved bits for VL32 encoding
02 00 00 00 = 2 bytes of value length (32 bit encoding)
00 80 = 32768 (in decimal)

Question :

What is the meaning of 32768 ? Since I read in the supplement 30 specification that "Equipment which produces digitized waveform curves may encode a specific value when the source is disconnected or otherwise invalid. This value is encoded like the Waveform Data attribute with one sample only. The Waveform Padding Value need not be within the range specified by the Channel Minimum and Maximum Data Values"

In my case, if I have a stream of ECG signals, let's say :

2.602857 0.388133 0.285276 3.504505 3.658790 0.336704 0.015254 0.218097 1.083970 1.732829 0.262715 0.461522 (all in millivolt)

What should I put for my (5400,100a) value ?

Please advise,
Budhi

Hi Budhi,

DVTk is about testing healthcare standards like DICOM, HL7 and IHE. It is not used for creating DICOM software components. I think you will need to look for other fora that can help you.
