• CT_DataDCM.zip
  • Contains the recorded CT images of heart and torso in DCM file format
• ECG_NodeIndices.txt
  • Contains the the node IDs of the torso mesh corresponding to the electrode positions of the ECG Vest
• Endocardial_Surface_Papillary.stl
  • Segmented endocardial surface including papillary muscles
• Mat_LeadField.dat
  • Contains the calculated lead field matrix to be used in combination with the provided Mesh_Ven.vtu. Make sure to keep the node order

  • #  Python example of usage
    #  Define a read_vm_vec function which reads your calculated data beforehand
    import numpy as np

    result = np.zeros((len(times), 31))
    for i,t in enumerate(times):
        vm_vec = read_vm_vec(t)
        result[i, :] = LF_mat.dot(vm_vec)[0:31]
    result = np.insert(result, 0, times, axis=1)
    np.savetxt('BSPM.dat', result)
