Dataset Characteristics:¶

The dataset consists of 50 Computed Tomography Angiography (CTA) images, each with the following attributes:

• Axial Dimensions: The images vary in size, with the smallest being 389x389 pixels and the largest at 516x516 pixels. The average size across the dataset is 450x450 pixels.
• Voxel Resolution: Each image has an isotropic voxel resolution of 1mm x 1mm x 1mm, ensuring uniformity in measurement.
• Axial Slice Count: The number of axial slices per image ranges from 578 to 801, with an average of 695 slices.

Dataset Directory Structure:¶

The dataset is organized into a structured directory for ease of access and use. Below is the directory hierarchy:
