Hello,

I have a 150 slice thoracic volume, of which all of the slices are consistently visible in the slice-by-slice viewer.

My issue is in the Multiplanar Reconstruction or 3D Rendering of this volume. The in-built functions for this only use the first 100 slices of the volume, leaving the inferior third of the thorax from the reconstruction.

I have used these functions many times with other DICOM filesets, and this issue has only ever occurred before when loading multiple reconstructions of larger (data-wise) volumes simultaneously (I presume this is RAM-based), but occurs here in the absence of additional processing requirements.

In attempts to identify/solve the problem, I have isolated the volume of interest and tried loading only this before creating reconstructions, with no luck. I have also looked at the metadata of all of the files in this volume, which all seems to be consistent to that of a normal, functioning volume.

I have looked at other discussions on the forum and could not find any with the same issue. Apologies if I have missed one.

Any help appreciated

It happened for me with Head CT in axial volumes made with variable slice thickness/spacing.

I bet that the spacing between slices in Your dataset is not equal to others somewhere where the volume breaks.

Hi boskar,

I presumed the same originally, so made a code to compare the metadata between individual slices and highlight the differences - they were all consistent with one another, and variable data showed consistent intervals between slices.

The fileset seems to have a very irregular naming system with relation to series and instance number, so I have been considering this as another potential cause. Unfortunately I'm not that great with computers so can't predict the mechanics behind this.

We could check the cause of your issue if you were able to send us the problematic series. You can contact us directly via https://www.radiantviewer.com/contact/
