Abstract—In neurosurgery to remove brain tumors, DICOM data, a medical imaging standard, is generated preoperatively using CT and MRI. This data is used for surgical planning. However, brain deformities, known as brain shifts, can occur during surgery and deviate from the preoperative surgical plan. Deviations from the surgical plan due to brain shift are a life-threatening problem as they reduce the success rate of surgery. Brain shift has not yet been elucidated and DICOM data acquired by MRI and CT for surgical planning and post-operative management are stored and archived at hospitals and discarded after a certain period. To address these issues, we started research around 2018 with the goal of modelling brain shifts. This will enable surgical planning to take brain shifts into account during pre-operative conferences. The corresponding OpenCV feature points are extracted from the pre-operative and post-operative DICOM and the brain shift is extracted from their motion vectors. Here, the feature point extraction algorithms BRISK, AKAZE, ORB, and SIFT are compared and it is experimentally confirmed that BRISK and AKAZE have better brain shift extraction capability than the other two algorithms.
