🚀 Usage

Loading the Original Dataset

from tdsc_abus2023_pytorch import TDSC, DataSplits

# Initialize dataset with automatic download
dataset = TDSC(
    path="./data",
    split=DataSplits.TRAIN,
    download=True
)

# Access a sample
volume, mask, label, bbx = dataset[0]

Using the Tumor-Only Dataset

This dataset contains only tumor data, suitable for classification and segmentation tasks.

from tdsc_abus2023_pytorch import TDSCTumors, DataSplits

# Initialize dataset with automatic download
dataset = TDSCTumors(
    path="./data",
    split=DataSplits.TRAIN,
    download=True
)

# Access a sample
volume, mask, label = dataset[0]

View Transformers for changing the view

from tdsc_abus2023_pytorch import TDSC, DataSplits, ViewTransformer, ViewTransposeConfig
from enum import Enum
import numpy as np

view_transformer = ViewTransformer(view=ViewTransposeConfig.CORONAL)
dataset = TDSC(path="./data", split=DataSplits.TRAIN, transforms=[view_transformer])

# Get transformed sample
vol, msk, label, bbx = dataset[0]

Custom Transformers

from tdsc_abus2023_pytorch import TDSC, DataSplits, ViewTransformer, ViewTransposeConfig
from enum import Enum
import numpy as np

class MyTransformer:
    def __init__(self, my_params):
        # your params work here...
        pass

    def transform(self, vol):
        # Your transform strategy here...
        pass

    def __call__(self, vol, mask):
        # you should return vol & mask after transform
        return transform(vol), transform(mask)

view_transformer = ViewTransformer(view=ViewTransposeConfig.CORONAL)
my_transformer = MyTransformer(*args)


dataset = TDSC(path="./data", split=DataSplits.TRAIN, transforms=[view_transformer, my_transformer])

# Get transformed sample
vol, msk, label, bbx = dataset[0]
