Paper Abstract

In order for photon migration imaging to be clinically feasible, data acquisition must be fast and efficient. Rapid data acquisition minimizes error due to patient movement and improves patient acceptance. Multi-pixel imaging techniques offer the fastest method of data acquisition, however difficulties may exist in coupling the data with inversion algorithms. Single pixel measurements, while easier to couple to an inversion algorithm, require longer data acquisition times. Herein a heterodyne procedure for speeding the data acquisition time using single pixel techniques is presented. This simple extension of the heterodyne method enables the use of multiple sources simultaneously with the signal from various source-detector pairs discriminated by FFT analysis.
