^* False Positive Reduction Network (second stage).

Private data

Both aneurysm detection in TOF-MRA and rib fracture detection in CT Scans, our method achieved better results (w.o TTA) than nndetection (w. TTA). You are welcome to use it in other public data sets and can update its performance to me.

Installation

Create conda env

conda create -n env_name python==3.7

Install requirements

conda install pytorch torchvision torchaudio pytorch-cuda=11.6 -c pytorch -c nvidia
pip install SimpleITK==2.2.1 pandas==1.3.5 scikit-image==0.19.3 scipy==1.7.3

Train

bash train_xxx.sh

Note: args.num_sam depend on the average number of instance (lesion) in per sample (N), suggest you set to 2N. The real batch size is (args.batch_size * args.num_sam), be careful with your GPU memory.
