Waveform in Ultrasound Video

[manasamangipudi]

When I see Ultrasound video in Clarius Cloud, I see a waveform in it. I want to get the numerical values of that waveform, which can be useful for my project. Can anyone please give any details on how to access those values?

[clariusk]

do you mean waveform for pulsed wave doppler?

[manasamangipudi]

Yes, Is there anyway I can get it?

[clariusk]

you can only measure the velocity and time values in the App upon capturing the image

[manasamangipudi]

So, is there anyway I can get the same data from cloud? It would definitely help me

[clariusk]

no, they are just videos stored in the cloud

[manasamangipudi]

Yes, I understand that. Is it part of DICOM format data? Or is there some attribute in RAW files or anywhere else?

[clariusk]

you could try exporting as DICOM and the pixel attributes should be populated into the meta-data, from there certain DICOM viewers may have the correct tools to make the calculations

[manasamangipudi]

So, are you saying there is some attribute in DICOM data from which I can get the pulse doppler wave doppler values?

[clariusk]

this recent discussion highlights what tags to look at for obtaining pixel information: https://github.com/orgs/clariusdev/discussions/19

Also, does the pulse wave doppler contain information about any changes in the area of ultrasound scan? Can you please provide any documentation or details related to what that data exactly means?

I am not a DICOM user, the standard is vast and large, I recommend checking out our conformance statement to learn more: https://support.clarius.com/hc/en-us/articles/360020440972-Supporting-Documents
