Hi!
I 'm very new with DICOM images processing and with Python
I have **3DSlicer version 4.10.2** installed and the Python version I see in Python Interactor is:
> Python 2.7.13 (default, May 16 2019, 14:27:45) [MSC v.1900 64 bit (AMD64)] on win32
Is there a way to upgrade to Python 3.7?
The original reason for wanting to do this is because when trying to load DICOM files I get the following error:
> DICOM Plugin failed: ‘module’ object has no attribute ‘TemporaryDirectory’
and from what I 've read, an upgrade to python 3.7 may solve the problem
Thank you

Slicer-4.11 uses Python 3. It also has a greatly improved DICOM browser. See examples in [script repository](https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository) to see how you can manage DICOM files.

I have downloaded and installed Slicer-4.11, but still getting errors like the following and couldn’t load any DICOM file yet.
Thanks anyway!

That means that your DICOM files are corrupted. What software created them?

I only have the information from the file’s metadata, so I can see the following:
Source Application Entity Title: ECHOPAC
Manufacturer: GE Vingmed Ultrasound
Manufacturer’s Model Name: EchoPAC PC SW-Only

You may try running the image through DICOM patcher module to see if that can fix the format error.
Could you provide a sample image file (must not contain patient information; preferably an original scan of any object, not a patient)?

I run the DICOM patcher on the data and then, when I tried to import, I got the following errors and couldn’t import the data:
Unfortunately I’m not allowed to publish the files, even anonymized, and I don’t have access to the machine to get a new scan of an object.

It looks like your files are pretty badly formatted or maybe corrupted by some processing step. Since you can’t share them, a good path would be for you would be to study up on dicom. There are tons of books and web pages. Also try the [analyze tab on the innolitics site](https://dicom.innolitics.com) to better understand what’s going on inside.

I will. Thank you for your answers!
