Viewers: How to save measurements and annotations for a DICOM hosted in Orthanc?

Created on 17 Jul 2020 · 8Comments · Source: OHIF/Viewers

Hello!
As the title says, I'm trying to find a way to save the annotations to the dicom files hosted on Orthanc server.
I referred this, this and this issue, but I'm not sure how to implement the feature for Orthanc itself. Should some code changes be done on the back-end or is there a way to make the change from the front end?
Edits : Adding screenshots to describe the exact issue

Below image shows that the segmentation is getting done, and the measurements are successfully saved
Below image shows on refresh, that the segmentation is gone and so are the measurements:
For some reason, the annotations are going inside orthanc's server as a new instance, as shown below:

Is there any way to fix this? Instead of getting saved as an instance, can it be shown as expected, in the first screenshot?
Also, if the study list is not refreshed, the annotations on the dicom remain as expected.

Could anyone give some hints or documentation link to achieve this?

This is a known bug in OHIF when saving annotations to Orthanc

@ranasrule Would you please point me to an appropriate fix? Is there any way to save it properly like an extension? I'm referring to a couple of issues here, but not finding any leads

I haven't found a resolution myself. I reported this issue a while back at the following link and free others have too but nothing has been done about it. If you do find a resolution please do let me know as well.

@ranasrule Thanks for your responses. I'm continuing the conversation there as well to resolve this.

Hi, what I have to do to enable the feat to save annotations?

Hello, I ran into the same problem. How did you resolve this? Changing the docker container?
I am very new to this so I d like to ask for more details about how to save annotations. Right now I am trying to create a tool that can save measurements from a point in a CT scan (like values from Probe tools) as well as some identifications like patient ID, date, into a csv file. I was looking at this:

Else, the save measurements from elliptical annotations into some form that I can read later works as well. However, when I tried to save measurements in Orthanc the measurement appeared as a container without the measurements in json file. I am not sure what I am missing to get this to work. What do you think is the best way to approach this? Thank you.
