Hi. I’m doing my master’s thesis and I´m getting desperat…

When I load the magnetic ressonance images in format dcm, only one plan (coronal, sagittal, axial) is defined. The images from the other plans are blurry and poorly defined.  
In the example, coronal plan is ok, but sagittal and axial are indefined and with poor resolution.

And when I go to “Volume rendering”, the volume is not filled, as you can see in the following image.

How can I do to solve this?

Thank you so much for the support.

It looks like you have the same problem discussed here:

> Operating system: Mac - High Sierra Slicer version: 4.8.1 Expected behavior: One perfect, high resolution volume Actual behavior: Three volumes, each one being high resolution in only one plane (sagittal, coronal, transverse) I have been using 3D Slicer for many months and I’m slowly learning the ropes. I am using it to produce anatomical boney models, and have probably created between 10-15 models. After loading CT scans from their DICOM folder I always get several volumes, often with the …
