}
The code has been tested with Python 3.8 on Ubuntu 20.04 LTS. The following Python packages are required (lower versions may also be sufficient):
- efficientnet_pytorch >= 0.6
- torch >= 1.6
- scikit-image >= 0.17.2
- PyYAML >= 5.4.1
- opencv-python >= 4.5.2
- SimpleITK >= 2.0.2
It is recommended to install the package in a separate virtual environment created with , e.g., virtualenv or (mini)conda.
git clone https://github.com/IPMI-ICNS-UKE/DeepTICI
cd DeepTICI
pip install .Example usage for predicting a TICI score for a given two-views (i.e. lateral and frontal) DSA series (original M1 occlusion). Model weights from all experiments performed in our recent publication are included and can be seperately used for automatic TICI scoring (selectable via predict_experiment_I/predict_experiment_III/predict_ensemble methods in configuration.yml).
from DeepTICI import predict
dcm_paths = ['/some/path/to/view/1', '/some/path/to/view/2']
tici_score = predict.predict_series(dcm_paths)
print(tici_score)Fine tuning on personal data is supported:
from DeepTICI import model
from DeepTICI.helper import ModelMode, OutputMode
# model init
model = model.TICIModelHandler(num_classes=5, feature_size= 1280, in_channels=3)
# forward pass
for data in data_loader:
# DCM-series with shape: batch x time x 2 (views) x height x width
img = data[0]
series_lenghts = data[1]
output = model(x=img, series_lenghts=series_lenghts, model_mode=ModelMode.train, output_mode=OutputMode.last_frame)
# loss, backward-pass, etc.Implementation of the first fully automatic TICI-scoring system. The system is based on a combination of encoder, GRU
and classifier. Details of our proposed method can be found in the following MICCAI contribution:
Time Matters: Handling Spatio-Temporal Perfusion Information for Automated TICI Scoring
A detailed performance analysis is available in Stroke:
