CleanX is an open source python library for exploring, cleaning and augmenting large datasets of X-rays, or certain other types of radiological images. JPEG files can be extracted from DICOM files or used directly.

Continous Integration (CI) status
- a python installation (3.7, 3.8
- ability to create virtual environments (recommended, not absolutely
- optional recommendation of
pydicomfor DICOM/dcm to JPG
- Anaconda is now supported, but not technically necessary
Please refer to Developer's Giude
for more detailed explanation.
Developing Using Anaconda's Python
Use Git to check out the project's source, then, in the source
conda create -n cleanx
conda activate -n cleanx
python ./setup.py install_dev
You may have to do this for Python 3.7, Python 3.8 and Python 3.9 if
you need to check that your changes will work in all supported
Developing Using python.org's Python
Use Git to check out the project's source, then in the source
python -m venv .venv
python ./setup.py install_dev
conda based setup, you may have to use Python versions
3.7, 3.8 and 3.9 to create three different environments to recreate
our CI process.
cleanX package is a pure Python package, but it has many
dependencies on native libraries. We try to test it on as many
platforms as we can to see if dependencies can be installed there.
Below is the list of platforms that will potentially work.
Whether python.org Python or Anaconda Python are supported, it means
that version 3.7, 3.8 and 3.9 are supported. We know for certain that
3.6 is not supported, and there will be no support in the future.
32-bit Intell and ARM
We don't know if either one of these is supported. There's a good
chance that 32-bit Intell will work. There's a good chance that ARM
It's unlikely that the support will be added in the future.
Seems to be unsupported at the moment on both Linux and OSX, but it's
likely that support will be added in the future.

You can also build up-to-date documentation by command.
Documentation can be generated by command:
python setup.py apidoc
python setup.py build_sphinx
The documentation will be generated in
directory. Documentation is generated automatically as new functions
Special additional documentation for medical professionals with
limited programming ability is available on the wiki
To get a high level overview of some of the functionality of the
program you can look at the Jupyter notebooks inside workflow_demo.
setting up a virtual environment is desirable, but not absolutely
activate the environment
- use command for conda as below
conda install -c doctormakeda -c conda-forge cleanx
You need to specify both channels because there are some cleanX
dependencies that exist in both Anaconda main channel and in
- use pip as below
pip install cleanX
We will imagine a very simple scenario, where we need to automate
normalization of the images we have. We stored the images in
/images/to/clean/ and they all have
jpg extension. We
want the cleaned images to be saved in the
Normalization here means ensuring that the lowest pixel value (the
darkest part of the image) is as dark as possible and that the
lightest part of the image is as light as possible.
The problem above doesn't require writing any new Python code. We can
accomplish our task by calling the
cleanX command like this:
python -m cleanX images run-pipeline \
-s Acqure \
-s Normalize \
-s "Save(target='cleaned')" \
Let's look at the command's options and arguments:
python -m cleanXis the Python's command-line option for loading
cleanXpackage. All command-line arguments that follow this
part are interpreted by
imagessub-command is used for processing of images.
run-pipelinesub-command is used to start a
-s(repeatable) option specifies
Step. Steps map to
their class names as found in the
__init__function of a step doesn't take any arguments, only
the class name is necessary. If, however, it takes arguments, they
must be given using Python's literals, using Python's named arguments
-joption instructs to create journaling pipeline. Journaling
pipelines can be restarted from the point where they failed, or had
-rallows to specify source for the pipeline. While, normally, we
will want to start with
Acquirestep, if the pipeline was
interrupted, we need to tell it where to look for the initial
Once the command finishes, we should see the
cleaned directory filled
with images with the same names they had in the source directory.
Let's consider another simple task: batch-extraction of images from
python -m cleanX dicom extract \
-i dir /path/to/dicoms/
cleanX CLI in the way similar to the example above, however,
it calls the
dicom sub-command with
cleanXto look for directory named
cleanXto save extracted JPGs in
If you have any problems with this check
#40 and add
issues or discussions.
Below is the equivalent code in Python:
from cleanX.image_work import (
dst = 'cleaned'
src = GlobSource('/images/to/clean/*.jpg')
p = create_pipeline(
Let's look at what's going on here. As before, we've created a
create_pipeline with three steps:
Save. There are several kinds of sources available
for pipelines. We'll use the
GlobSource to match our CLI example.
journal=True to match the
-j flag in our CLI
And for the DICOM extraction we might use similar code:
from cleanX.dicom_processing import DicomReader, DirectorySource
dst = 'extracted'
reader = DicomReader()
reader.rip_out_jpgs(DirectorySource('/path/to/dicoms/', 'file'), dst)
This will look for the files with
dcm extension in
/path/to/dicoms/ and try to extract images found in those files,
saving them in
About using this library
If you use the library, please credit me and my collaborators. You
are only free to use this library according to license. We hope that
if you use the library you will open source your entire code base, and
send us modifications. You can get in touch with me by starting a
(https://github.com/drcandacemakedamoore/cleanX/discussions/37) if you
have a legitimate reason to use my library without open-sourcing your
code base, or following other conditions, and I can make you
specifically a different license.
We are adding new functions and classes all the time. Many unit tests
are available in the test folder. Test coverage is currently
partial. Some newly added functions allow for rapid automated data
augmentation (in ways that are realistic for radiological data). Some
other classes and functions are for cleaning datasets including ones
- Get image and metadata out of dcm (DICOM) files into jpeg and csv
- Process datasets from csv or json or other formats to generate
- Run on dataframes to make sure there is no image leakage
- Run on a dataframe to look for demographic or other biases in
- Crop off excessive black frames (run this on single images) one at a
- Run on a list to make a prototype tiny Xray others can be compared
- Run on image files which are inside a folder to check if they are
- Take a dataframe with image names and return plotted(visualized)
- Run to make a dataframe of pics in a folder (assuming they all have
the same 'label'/diagnosis)
- Normalize images in terms of pixel values (multiple methods)
All important functions are documented in the online documentation for
programmers. You can also check out one of our videos by clicking the
