Synthetic Shapes for ORMIR_XCT Thickness Measurement Validation

These shapes were generated to validate a distance transform function implemented for the Python ORMIR_XCT package. Shapes generated include: solid spheres, solid cylinders, hollow spheres, hollow cylinders, and plates. Each shape was also bound along the long axis of the shape to simulate images where no padding exists around the object. All shapes have a voxel size of 0.0607 mm^3 to simulate second generation HR-pQCT (XtremeCT2, Scanco Medical) image data. Image naming convention is as follows: <strong>Solid (filled) Spheres: </strong>F_SPH_OUTR_X.nii Radius of the sphere = X <strong>Solid (filled) Cylinders:</strong> F_CYL_OUTR_X_LEN_Y.nii Radius of the cylinder = X Length of the cylinder = Y <strong>Hollow Spheres:</strong> H_SPH_OUTR_X_INR_Y.nii Outer radius of the sphere = X Inner radius of the sphere = Y <strong>Hollow Cylinders: </strong>H_CYL_OUTR_X_INR_Y_LEN_Z.nii Outer radius of the cylinder = X Inner radius of the cylinder = Y Length of the cylinder = Z <strong>Plates:</strong> PLATE_WIDTH_X_LEN_Y.nii Width (i.e., thickness) of the plate = X Length of the plate = Y (plates are all squares) <strong>Bounding Shapes:</strong> Same naming convention as above with "BOUNDING" at the end
