2D MPR crashes on some CTs with RangeError: Array buffer allocation failed.

[muddasar-de]

We have the CTs with the following details,
Dimensions: 512 x 512
Number of slices: 2500 to 3500
OS: Windows
Browsers: Google Chrome and Firefox
System RAM: 16GB

This problem is for both Local and Cloud environment(AWS) as well.

Please provide details about the CT data that fails, like the slice dimensions, number of slices, and what clinical procedure this comes from. Also describe your environment, like what OS, browser, how much memory your machine has, etc.

Thanks for the extra details. I have also seen array buffer allocation fail for a scan with 2000 slices. I'm not sure there's a planned work around. @sedghi has may be able to comment.

Appreciate for the response and help.
Looking for the @sedghi response.

There are some plans for this. @Ouwen has written a POC for how to split the slices into different sections and let the user see the first sectoin, until it scrolls to the bottom and it automatically triggers going to next section, maybe he can talk about that. In addition to these kinds of tricks, we are working on the INT_16 texture size which reduces the memory in half, but seems like it has some bugs in Chromium and Safari, more on that here

Hi @muddasar-de for desktop use you can increase the memory limit from 1GB to 2GB and it should work with this PR into cornerstone3D-beta:

cornerstonejs/cornerstone3D#420

There is also a partial load PR I am working on which is based on invalidating the displaySetUID

[Ouwen]

@muddasar-de see this PR: #3235

Hi we are facing a similar issue. Wondering if there was any progress on this issue.

Issue description

Clicking the 2D MPR button will consume the entire machine's RAM, temporarily crash the browser and then render blank images on the DICOM Viewer.

Our image:

• Foot CT
• 533 slices
• 950 x 950
• 35D x 20H

Browser: Chrome

Machine:

• Dell XPS
• RAM: 32GB
• GPU: NVIDIA RTX 3050 Ti GPU

Mysteriously we have been able to succeed in using the 2D MPR feature for the same scan with several different machines (Macbook Air M1 with 8GB RAM, Macbook Pro with 16GB RAM, and Lenovo Legion with 32GB RAM and RTX 3060 GPU).
