Analysis Software for the Photon Migration Amplitude Cancellation Portable Breast Tumor Imaging System Developed in Matlab.

We were asked to write analysis software to process the data output of the portable breast tumor imaging system.  The data was a set of two 6 x 6 matrices of voltage readings.  The readings represented the amount of light absorbed by sensors mounted on the imaging pad: one matrix represented the readings at 750 nm for oxy-hemoglobin, and the other represented the readings at 830 nm for deoxy-hemoglobin.

Portable Breast Tumor Imaging System Developed in Matlab

The software was developed in Matlab v5.2.  We created a graphical user interface (GUI) that made analysis significantly less cumbersome by allowing the user to analyze data through mouse clicks in one interface instead of typing a series of commands in different programs.  Not only was the system easier to use, but it reduced analysis time from approximately 5 minutes to less than 30 seconds per data set.

I hope that you will find our work to be useful in some way.  If you have any questions, please feel free to e-mail me.
