Operating system: Win10  
Slicer version: 4.10.2  
Expected behavior: Obtaining 3D model of my head  
Actual behavior: Seeing images but not sure the good way

Hi, I’m really new to 3D Slicer and all of those MRI stuff.  
I’m french, so you can contact me in this language if you want.

I’ve got a recent MRI of a head on a CD-ROM.  
The directory structure of the CD-ROM is shown below :  
 ![image](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/4/2/42f2e560ae4577c1694e20e26ad3ea1f8182b530.png)  
As you can see, there is no file extension. But the files are DICOM files from an Optima MR360 (as seen in a hexadecimal version of one of a DICOM files).

I’m trying to load those files in Slicer 3D.

**First question :** Can I load all the SE1, SE2, SE3, SE4, … SE8 folders, or should I load only one ?

When loading just one file by dragging and dropping the first file, it’s ok :

 ![image](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/c/4/c435ce301996f8598d5b679b6753c59071268d3f.png)

I choose the “Show options” and deselect “Single file”, then I press OK.

 ![image](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/c/0/c0c844271e018981413f8965f378ae05ada698ba.png)

I choose the “Volumes” module, and display “Volume information”.

 ![image](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/c/0/c03ee82b75e40fb0ff72b3c000aa8cf549a6cf3b.png)  
**Second question :** Do I need to chance something on this “Volumes” module ?

I try next to use the “Vector to scalar” module, but I really don’t know if it’s necessary, or what to do (the input vector volume dropdown list is empty).  
 ![image](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/e/3/e32a89236efed725652342ff0fc78737e170ca5d.png)

If I choose the “Volume rendering” module, and playing with “Preset” dropdown list, I obtain (after clicking on the closed eye next to “Volume :” label) a king of 3D, but that’s not a head…

**Question 3 :** Can you help me to have a good result with the CDRom datas ?

Cordially

What you have is DICOM data, so you will need to import it (the folder PA1) to the DICOM database using the DICOM browser and load from there.

Thank you @cpinter !  
I think there is a issue with the DICOM Browser.  
I don’t know where is the option to “Show DICOM browser”.

And when I read the error windows, there is a critical error when launching the DICOM module :

```
Traceback (most recent call last):

```

I think I have a bug ? isn’t it ?

Can you help me once again ?

Thank you

I would recommend to try with latest Slicer Preview Release, as it contains fixes for many common issues with the DICOM browser.

Thank you !  
No problem with the preview release.
