Welcome to the new and improved MOOSE (v3.0), where speed and efficiency aren't just buzzwordsβthey're a way of life.
π¨ 3x Faster Than Before
Like a moose sprinting through the woods (okay, maybe not that fast), MOOSE 3.0 is built for speed. It's 3x faster than its older sibling, MOOSE 2.0, which was already no slouch. Blink and you'll miss it. β‘
π» Memory: Light as a Feather, Strong as a Bull
Forget "Does it fit on my laptop?" The answer is YES. πΊ Thanks to Dask wizardry, all that data stays in memory. No disk writes, no fuss. Run total-body CT on that 'decent' laptop you bought three years ago and feel like youβve upgraded. π₯³
π οΈ Any OS, Anytime, Anywhere
Windows, Mac, Linuxβwe donβt play favorites. π Mac users, youβre in luck: MOOSE runs natively on MPS, getting you GPU-like speeds without the NVIDIA guilt. π
π― Trained to Perfection
This is our best model yet, trained on a whopping 1.7k datasets. More data, better results. Plus you can run multiple models at the same time - You'll be slicing through images like a knife through warm butter. (Or tofu, if you prefer.) π§πͺ
π₯οΈ The 'Herd' Mode π₯οΈ
Got a powerhouse server just sitting around? Time to let the herd loose! Flip the Herd Mode switch and watch MOOSE multiply across your compute like... well, like a herd of moose! π¦π¦π¦ The more hardware you have, the faster your inference gets done. Scale up, speed up, and make every bit of your server earn its oats. πΎπ¨
MOOSE 3.0 isn't just an upgradeβit's a lifestyle. A faster, leaner, and stronger lifestyle. Ready to join the herd? π¦β¨

pip install moosez
There you have it! You're ready to venture into the world of 3D medical image segmentation with MOOSE 3.0.
Happy exploring! ππ¬
Getting started with MOOSE 3.0 is as easy as slicing through butter π§πͺ. Use the command-line tool to process multiple segmentation models in sequence or in parallel, making your workflow a breeze. π¬οΈ
You can now run single or several models in sequence with a single command. Just provide the path to your subject images and list the segmentation models you wish to apply:
# For single model inference
moosez -d <path_to_image_dir> -m <model_name>
# For multiple model inference
moosez -d <path_to_image_dir> \
-m <model_name1> \
<model_name2> \
<model_name3> \
For instance, to run clinical CT organ segmentation on a directory of images, you can use the following command:
moosez -d <path_to_image_dir> -m clin_ct_organs
Likewise, to run multiple models e.g. organs, ribs, and vertebrae, you can use the following command:
moosez -d <path_to_image_dir> \
-m clin_ct_organs \
clin_ct_ribs \
clin_ct_vertebrae
MOOSE 3.0 will handle each model one after the otherβno fuss, no hassle. πβ¨
Got a powerful server or HPC? Let the herd roam! π¦π Use Herd Mode to run multiple MOOSE instances in parallel. Just add the -herd
flag with the number of instances you wish to run simultaneously:
moosez -d <path_to_image_dir> \
-m clin_ct_organs \
clin_ct_ribs \
clin_ct_vertebrae \
-herd 2
MOOSE will run two instances at the same time, utilizing your compute power like a true multitasking pro. πͺπ¨βπ»π©βπ»
And that's it! MOOSE 3.0 lets you process with ease and speed. β‘β¨
Need assistance along the way? Don't worry, we've got you covered. Simply type:
moosez -h
This command will provide you with all the help and the information about the available models and the regions it segments.
MOOSE 3.0 isn't just a command-line powerhouse; itβs also a flexible library for Python projects. Hereβs how to make the most of it:
First, import the moose
function from the moosez
package in your Python script:
from moosez import moose
The moose
function is versatile and accepts various input types. It takes four main arguments:
input
: The data to process, which can be:- A path to an input file or directory (NIfTI, either
.nii
or.nii.gz
). - A tuple containing a NumPy array and its spacing (e.g.,
numpy_array
,(spacing_x, spacing_y, spacing_z)
). - A
SimpleITK
image object.
- A path to an input file or directory (NIfTI, either
model_names
: A single model name or a list of model names for segmentation.output_dir
: The directory where the results will be saved.accelerator
: The type of accelerator to use ("cpu"
,"cuda"
, or"mps"
for Mac).
Here are some examples to illustrate different ways to use the moose
function:
-
Using a file path and multiple models:
moose('/path/to/input/file', ['clin_ct_organs', 'clin_ct_ribs'], '/path/to/save/output', 'cuda')
-
Using a NumPy array with spacing:
moose((numpy_array, (1.5, 1.5, 1.5)), 'clin_ct_organs', '/path/to/save/output', 'cuda')
-
Using a SimpleITK image:
moose(simple_itk_image, 'clin_ct_organs', '/path/to/save/output', 'cuda')
To use the moose()
function, ensure that you wrap the function call within a main guard to prevent recursive process creation errors:
from moosez import moose
if __name__ == '__main__':
input_file = '/path/to/input/file'
models = ['clin_ct_organs', 'clin_ct_ribs']
output_directory = '/path/to/save/output'
accelerator = 'cuda'
moose(input_file, models, output_directory, accelerator)
That's it! With these flexible inputs, you can use MOOSE 3.0 to fit your workflow perfectlyβwhether youβre processing a single image, a stack of files, or leveraging different data formats. π₯οΈπ
Happy segmenting with MOOSE 3.0! π¦π«
Using MOOSE 3.0 optimally requires your data to be structured according to specific conventions. MOOSE 3.0 supports both DICOM and NIFTI formats. For DICOM files, MOOSE infers the modality from the DICOM tags and checks if the given modality is suitable for the chosen segmentation model. However, for NIFTI files, users need to ensure that the files are named with the correct modality as a suffix.
Please structure your dataset as follows:
MOOSEv2_data/ π
βββ S1 π
β βββ AC-CT π
β β βββ WBACCTiDose2_2001_CT001.dcm π
β β βββ WBACCTiDose2_2001_CT002.dcm π
β β βββ ... ποΈ
β β βββ WBACCTiDose2_2001_CT532.dcm π
β βββ AC-PT π
β βββ DetailWB_CTACWBPT001_PT001.dcm π
β βββ DetailWB_CTACWBPT001_PT002.dcm π
β βββ ... ποΈ
β βββ DetailWB_CTACWBPT001_PT532.dcm π
βββ S2 π
β βββ CT_S2.nii π
βββ S3 π
β βββ CT_S3.nii π
βββ S4 π
β βββ S4_ULD_FDG_60m_Dynamic_Patlak_HeadNeckThoAbd_20211025075852_2.nii π
βββ S5 π
βββ CT_S5.nii π
Note: If the necessary naming conventions are not followed, MOOSE 3.0 will skip the subjects.
When using NIFTI files, you should name the file with the appropriate modality as a suffix.
For instance, if you have chosen the model_name
as clin_ct_organs
, the CT scan for subject 'S2' in NIFTI format, should have the modality tag 'CT_' attached to the file name, e.g. CT_S2.nii
. In the directory shown above, every subject will be processed by moosez
except S4.
Remember: Adhering to these file naming and directory structure conventions ensures smooth and efficient processing with MOOSE 3.0. Happy segmenting! π
All of our Python packages here at QIMP carry a special signature β a distinctive 'Z' at the end of their names. The 'Z' is more than just a letter to us; it's a symbol of our forward-thinking approach and commitment to continuous innovation.
Our MOOSE package, for example, is named as 'moosez', pronounced "moose-see". So, why 'Z'?
Well, in the world of mathematics and science, 'Z' often represents the unknown, the variable that's yet to be discovered, or the final destination in a series. We at QIMP believe in always pushing boundaries, venturing into uncharted territories, and staying on the cutting edge of technology. The 'Z' embodies this philosophy. It represents our constant quest to uncover what lies beyond the known, to explore the undiscovered, and to bring you the future of medical imaging.
Each time you see a 'Z' in one of our package names, be reminded of the spirit of exploration and discovery that drives our work. With QIMP, you're not just installing a package; you're joining us on a journey to the frontiers of medical image processing. Here's to exploring the 'Z' dimension together! π
