🚀 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]

Data Transformers for Preprocessing

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

class ViewTransformer:
    class View(Enum):
        CORONAL = 0
        SAGITTAL = 1
        AXIAL = 2
    
    TRANSPOSE_CONFIGS = {
        View.AXIAL: (0, 1, 2),
        View.CORONAL: (1, 2, 0),
        View.SAGITTAL: (2, 0, 1)
    }
    
    def __init__(self, view: View):
        self.transpose_axes = self.TRANSPOSE_CONFIGS[view]
    
    def __call__(self, vol: np.ndarray, mask: np.ndarray):
        transformed_vol = np.transpose(vol, self.transpose_axes)
        transformed_mask = np.transpose(mask, self.transpose_axes)
        return transformed_vol, transformed_mask

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

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