Hi dear. I have been working on Biomedical imaging with different latest techniques, e.g., X-ray/CT, PET, SPECT, MRI, NIRS, EEG, EMG etc. The estimation of desired intensity/power for a desired depth excitation determines the spatial resolution of the system. I can complete your task with perfection that will include description of calculation methodology, calculations, Matlab coding, plotted result, and discussion about the calculated/estimated model parameters.
Please feel free to contact for further discussion.
