Missing ROI position/size metadata for RAW RF acquisitions?

[Karl-Philippe]

Hi,

I’m working with RF data and can’t find any metadata describing the RF acquisition ROI (its position or size). It doesn’t appear in the DICOM tags, nor in the *_env.yml / *_rf.yml files.

Is this information stored anywhere, or currently not exposed?

Thanks!

the _rf.yml file will have the information:

for example:
size: {samples per line: 528,number of lines: 104,sample size: 2 bytes}
sampling rate: 20 MHz
delay samples: 281

lines:
-- {rx element: 48,tx element: 48,angle: 0 °,duration: 81 µs}
