Abstract
Abstract
This synthetic dataset or phantom consists of 6 raw format databases, in the three–dimensional (3-D) domain, which are identified as follows:
DB1: Ground Truth
DB2: Poisson noise
DB3: Stair-step artifact
DB4: Streak artifact
DB5: Both artifacts
DB6: Hybrid.
The dataset considers two cones in order to simulate the human heart endocardium and the wall of the main heart chamber called the left ventricle. The 3-D computer-generated cardiac phantom is shown as a double truncated cone.
Each database consists of images with intensity information (gray levels), is quantized to 16 bits and its spatial resolution is 256 × 256 × 50 voxels. The value 256 is equivalent to 50% of the spatial dimension of a typical cardiac CT layer and the value 50 corresponds to approximately 20% of the number of layers of the one real cardiac computed tomography database analyzed.
Comments
This dataset could be used in validation process related to digital image processing techniques.
