This dataset contains 2D image slices extracted from the publicly available Pancreas-CT-SEG dataset, which provides manually segmented pancreas annotations for contrast-enhanced 3D abdominal CT scans. The original dataset was curated by the National Institutes of Health Clinical Center (NIH) and was made available through the NCI Imaging Data Commons (IDC). The dataset consists of 82 CT scans from 53 male and 27 female subjects, converted into 2D slices for segmentation tasks.

Dataset Details:

Modality: Contrast-enhanced CT (portal-venous phase, ~70s post-injection)

Number of Subjects: 82

Age Range: 18 to 76 years (Mean: 46.8 ± 16.7 years)

Scan Resolution: 512 × 512 pixels per slice

Slice Thickness: Varies between 1.5 mm and 2.5 mm

Scanners Used: Philips and Siemens MDCT scanners (120 kVp tube voltage)

Segmentation: Manually performed by a medical student and verified by an expert radiologist

Data Format: Converted from 3D DICOM/NIfTI to 2D PNG/JPEG slices for segmentation tasks

Total Dataset Size: ~1.85 GB

Category: Non-cancerous healthy controls (No pancreatic cancer lesions or major abdominal pathologies)

Preprocessing and Conversion:

The original 3D CT scans and corresponding pancreas segmentation masks (available in NIfTI format) were converted into 2D slices to facilitate 2D medical image segmentation tasks. The conversion steps include:

Extracting axial slices from each 3D CT scan.

Normalizing pixel intensities for consistency.

Saving images in PNG/JPEG format for compatibility with deep learning frameworks.

Generating corresponding binary segmentation masks where the pancreas region is labeled.

Dataset Structure:

Applications

This dataset is ideal for medical image segmentation tasks such as:

Deep learning-based pancreas segmentation (e.g., using U-Net, DeepLabV3+)

Automated organ detection and localization

AI-assisted diagnosis and analysis of abdominal CT scans
