|
This model can be used to reconstruct single coil fastMRI data with an acceleration factor of 4. |
|
|
|
## Model description |
|
For more details, see https://www.mdpi.com/2076-3417/10/5/1816. |
|
This section is WIP. |
|
|
|
## Intended uses and limitations |
|
This model can be used to reconstruct single coil knee data from Siemens scanner at acceleration factor 4. |
|
It cannot be used on multi-coil data. |
|
|
|
## How to use |
|
This model can be loaded using the following repo: https://github.com/zaccharieramzi/fastmri-reproducible-benchmark. |
|
After cloning the repo, `git clone https://github.com/zaccharieramzi/fastmri-reproducible-benchmark`, you can install the package via `pip install fastmri-reproducible-benchmark`. |
|
The framework is TensorFlow. |
|
|
|
You can initialize and load the model weights as follows: |
|
```python |
|
from fastmri_recon.models.functional_models.pdnet import pdnet |
|
|
|
model = pdnet() |
|
model.load_weights('model_weights.h5') |
|
``` |
|
|
|
Using the model is then as simple as: |
|
```python |
|
model([ |
|
kspace, # shape: [n_slices, n_rows, n_cols, 1] |
|
mask, # shape: [n_slices, n_rows, n_cols] |
|
]) |
|
``` |
|
|
|
## Limitations and bias |
|
The limitations and bias of this model have not been properly investigated. |
|
|
|
## Training data |
|
This model was trained using the [fastMRI dataset](https://fastmri.org/dataset/). |
|
|
|
## Training procedure |
|
The training procedure is described in https://www.mdpi.com/2076-3417/10/5/1816 for brain data. |
|
This section is WIP. |
|
|
|
## Evaluation results |
|
This model was evaluated using the [fastMRI dataset](https://fastmri.org/dataset/). |
