Table 1.

Characterization comparison among various modes of SPECT. One may note view area increase is over single-pinhole case. Multiplexing percentage is the overlap area divided by the detector plane with a simulated 17.6×12.8 mm2 rectangular object whose area is big enough to cover the thyroid region of a mouse.
