BoneCementInjectionPlanning

What is this?

This repository provides the code for running BICEPS (Bone Injection of CEment Planning System). BICEPS takes a CT image of a patient with one or more Vertebral Compression Fractures and generates an estimation of the healthy state of the patients spine to enable treatment planning. The methodology was first introduced and is described in Patient-specific virtual spine straightening and vertebra inpainting: An automatic framework for osteoplasty planning.

Installation:

The code has been implemented using Python 3.7. To install the necessary packages for this framework run:

pip install -r requirements.txt

How does this work?

To run this framework the user needs to specify two inputs, the patient directory and the vertebra fracture id. For example:

python main.py --patient_dir ./patient01/ --fracture 22

The patient directory must include a sub-directory with the fractured scan; this can be named arbitrarily but should include the chars 'ct' in it. Additionally, the directory can also include scans of the pre-fractured, healthy, state and post-operative state (again the scans in these sub-directories must include 'ct' in them). The sub-directories are named with the date of the scan. Then the framework will include these in the analysis by adding either --healthy or --post_op as arguments when running main. An example of the structure is as follows:

--patient01
  --02052016
    --ct_scan.nii
  --04122019
    --ct_scan.nii
  --20122019
    --ct_scan.nii
    --mask_scan.nii

The vertebra - label correspondence is as follows:

Vertebra	Label
C1	1
C2	2
...	...
C7	7
T1	8
...	...
T12	19
L1	20
...	...
L5	24

Additional optional arguments the user may provide are:

height_scale: *to be described*
visualize: If set the scans and masks of all steps are shown using napari - caution can be expensive to visualize all steps' outputs
save: If set the intermediate scans are stored
