Meply: A Large-scale Dataset and Baseline Evaluations for Metastatic Perirectal Lymph Node Segmentation
CoSAM Overview
The frame work of our proposed CoSAM. The code of CoSAM is provided in code/cosam.py.
Dataset Overview
The Metastatic Perirectal Lymph node dataset (MEPLY), encompassing 269 enhanced computed tomography (CT) scans with a voxel resolution of 0.625mm, is tailored for the specific task of lymph node segmentation. Annotating each scan meticulously, Meply offers invaluable data facilitating precise delineation of perirectal lymph nodes.
Dataset Example
We provide examples of our dataset in examples. Each npz file contains a dictionary with the following keys:
img: a numpy array of shape (H, W, D) representing the CT sequence.label: a numpy array of shape (H, W, D) representing the ground truth lymph nodesegmentation mask.H = W = 512,D = 15
An example of how to load the data and visualize it is given in lymph_dataloader.py.
