Data from two Dynamical Contrast Enhanced Computer Tomography (DCE-CT) image sequences realized one patient of the cohort REMISCAN before treatment starts (t0) and after 15 days of treatment (t1). These are the real data used to illustrate the paper in References.


Each dataset contains a variable ex_dcemri which is a list containing #'

  • AIF, numeric vector, the averaged enhancement curve recorded in the aorta, the convolution kernel

  • TUM_1, TUM_2, TUM_3, numeric vectors, three averaged enhancement curves recorded in homogenous regions in the tumor, the observations

  • times, numeric vector, the observation times

  • sigma, numeric, the noise level

  • delta, numeric, equals 0, a time shift assumed to be less than 1 time unit
