Sample noise-free projection data of the cold sphere phantom are used to demonstrate the multiplexing schemes. Four degrees of multiplexing are obtained by (a) adjusting the 4-pinhole pattern (0%, 22%, 38% and 42%), and (b) increasing the pinhole number from 4- to 9-pinholes (0%, 19%, 39% and 60%) for the cold sphere phantom.
