I was today using CBCT data exported as dcm multiframe images of patients.
I used 3D Slicer to import the .dcm file and when it was importing it gave a warning in advance mode saying " Multi-frame image. If slice orientation or spaicing is non-uniform then the image may be displayed incorretly. Use with caution"
And after importing anyway when i use volume rendering to visualize the bones, i realized the rendered image is scaled or compressed or skewed i dont know what exactly but “not proper”.
So i went back and used gdcmconv to uncompressed the .dcm file and used the uncompressed dcm file in the 3D slicer. Then the volume rendering was accurate.
Why is this ? Is there a way of properly importing the compressed cbct data directly to 3D Slicer without using gdcmconv and cli ?
I cannot share the screenshots due to i did not seek permission from the patient to use the data in public.
