[Bug] Loading speed of ultrasound (US) study. (Videos or Sequences.)

[VetsImaging]

Describe the Bug

Now, I am using v3.8.0 (release) , connecting with ORTHANC on my local Windows11(pro) .
When we play ultrasound (US) study (videos or sequence), it doesn't play smoothly.
The loading speed seems slow.
After 30 seconds ~ a few minutes, it play smoothly.
Is there any solutions to play US study more smoothly, without waiting for a few minutes ?
I have uploaded screen capture videos as below ;
https://youtu.be/zDZNy25YMdk?si=o7QdcdbapXdxY6hb

As additional detail information,
I have posted this issue to Discourse of ORTHANC because I suspected the loading speed depends on ORTHANC performance.
Loading time of the ultrasound sequence file ;
https://discourse.orthanc-server.org/t/loading-time-of-the-ultrasound-sequence-file/4714/1
But they concluded that the loading speed is most likely depends on OHIF rather than ORTHANC.

Steps to Reproduce

1. git clone https://github.com/OHIF/Viewers.git
2. cd ./Viewers
3. switch branches/tags to v3.8.0 (release)
4. yarn install
5. yarn run dev:orthanc

• We don't modify any file in this repo.
• ORTHANC Version : 1.12.3 (installed by OrthancInstaller-Win64-24.5.1.exe)
  Configuration files : default (not changed )
• Specifications of my local computer is as below ;
  　CPU : intel core-i7 13700H
  　RAM : 16GB
  　Storage : SSD 1TB

The current behavior

When we play ultrasound (US) study (videos or sequence), it doesn't play smoothly.
The loading speed seems slow.
After 30 seconds ~ a few minutes, it play smoothly.

The expected behavior

When we play US videos, it play smoothly.
If it takes a time to loading US videos, it is better for user to show "loading bar" as v2.

Can you provide us with anonymized data?

[niirdan]

It doesn’t relate to a particular study, therefore every random cine from a US Will do to job. The authors video present the issue well I can send you an anonymous cine if you don’t have an examplary one

Is it only happening for Orthanc? since our server seems fine https://viewer.ohif.org/viewer?StudyInstanceUIDs=1.3.6.1.4.1.14519.5.2.1.1188.2803.137585363493444318569098508293

seems like we have improved upon this quite significantly i tried now and it was quite fast, can you try again?

here are related PRs

• fix(multiframe): metadata handling of NM studies and loading order  #4554
• fix: Having sop instance in a per-frame or shared attribute breaks load #4560

if it works fine, please close
Certainly only in master branch (3.10-beta)

Thanks so much for your improvement !
I will try to test on this weekend.
