Illustration of seesaw scanning mode for a two-headed SPECT system. The red arrow in the front displays the direction of the animal. In the lower right corner projections of a phantom are exhibited.
This movie illustrates a helical scanning orbit. The mult-pinhole aperture (the collimator and detector are not shown) rotates around the cylindrical object (gray) while the object itself translates along the axis of rotation. The actual field of view at a time is highlited in red.
In the upper right corner, multipinhole projections of a mouse are exhibited.
