+# Processed and Reduced Medical Segmentation Decathlon Dataset
+<!-- Provide a quick summary of the dataset. -->
+The miniMSD dataset is a medical image segmentation benchmark covering 10 human organs.
+It is derived from the [Medical Segmentation Decathlon (MSD)](http://medicaldecathlon.com) by converting volumetric scans
+from NIfTI (NII) format into serialised 2D RGB images, alongside their corresponding segmentation masks.
+The dataset is provided in multiple resolution variants (244, 512), enabling easier use,
+off-the-shelf accessibility, and flexible experimentation.
+
+## Dataset Details
+The dataset covers 10 human body organs, listed below.
+Each organ includes up to 40 volumes, with each volume consisting of a variable number of image slices.
+Each dataset entry contains the following components: the organ type, the image, a binary mask,
+a detailed (multi-class) mask, a volume ID, and a slice ID.
+The image, binary mask, and detailed mask are all provided as PIL images.
+The binary mask contains two labels: 0 for background and 1 for the target region.
+The detailed mask contains multiple labels (0, 1, 2, 3, …), where each label corresponds to a specific
+anatomical structure. The mapping of label indices to structures is provided below.
+
