mbirtorch geometry viewer

By Greg Buzzard

Choose a geometry and set the scan. The figure shows a 3D view, a top view of the xy plane, a side view of the yz plane, the detector face in row and channel index, and the derived numbers. Every panel draws negative z at the top, and the top and side views draw y to the left, so the source of the view at angle 0 is on the left and its detector is on the right.

The projector's own sinogram, computed when this page was built, for the default scan of each geometry.

sinogram of the cube phantom

A block a quarter of the volume wide, which shifts sideways from slice to slice.

3D camera elevation (deg)

Negative looks from above the drawing's top, which is the -z side.

3D camera azimuth (deg)

Degrees off the +x axis; 0 looks along x and shows the detector edge on.
