Configure DICOM image display size in Osimis Web Viewer

[alexg...@gmail.com]

Hi,

For some reason when I open CT/MRI Brain images the display size inside the osimis browser is very small. The image stays consistently small irrespective of the hanging protocol split view (1x1, 1x2, 2x2 etc). This doesn't seem to happen with Body regions (Chest/Aorta/Pelvis). I haven't checked extremities.

Is there a way to configure this?

I am using the Windows Version of Orthanc (64bit) on an HP Z600 as a test Vendor Neutral Archive.

Love this program BTW.

screenshot attached so you can see what I mean.

Any help much appreciated,

Alex

Hello Alex,

It is very likely the images are smalls because they have been stored in a small resolution.

You can check that in the Orthanc Explorer. Once you've selected a specific instance the Rows & Columns tags reflect the image resolution. Looking at your screenshot, the values should be near 256.

• 0028,0010 (Rows): 256
• 0028,0011 (Columns): 256

If it's not the case, it's a bug.

In the meanwhile, you can use the zoom tool.

Let me know if I can help you any further.

Kind Regards,

Thibault

Hi Thibault;

It could be particular to the Siemens 3T MRI we run and different fields of view that are used during image acquisistion.

You are correct that CT/MR images are usually 256*256 and the header in my test patient does display this.

I would be inclined to list this as a bug, only due to my experience with the normal behaviour of a PACS system (rather than a flaw in your code).

I have run AGFA and GE systems and used Carestream systems in the past, the usual behaviour is to fill the Viewport in the Hanging Protocol or have a configurable setting to consistently magnify the images to a particular size.

I've included some screen shots from my current PROD system + others loading an identical study

- GE RA1000 Thickclient,
- GE Universal Viewer (Web PACS Client)
- GE Centricity Web Viewer,
- RadiAnt Viewer,
- Osimis viewer

So you can see the comparisons


Thanks for your response,

Alex
