Abstract : Presently, the imaging techniques used for diagnosis and detection of breast cancer are all performed by deforming the breast from its original shape. The understanding of the biomechanical properties of breast tissue may be used to develop more accurate breast models. Such biomechanically-based models can be used to develop computer morphing algorithms so that the initial images obtained by shape deformation can be transformed into images that represent the breast in an un-deformed state. The primary purpose of our study is to investigate the biomechanical nature of normal breast tissue undergoing shape deformation due to external forces that are routinely used in diagnostic imaging of breast disease. In our investigations, external MR-visible markers and internal landmarks will be employed to permit localization and definition of coordinates of deformation. In preliminary studies, anatomical structures of the breast are found to provide unique internal landmarks.
