“…A confounding factor in DCE-MRI, from the point of view of registration, is the change in intensity over time generated by the contrast enhancement. This issue has been tackled by a number of authors who propose a variety of methods to separate this enhancement from the effects of patient motion (Ebrahimi andMartel 2009, Melbourne et al 2011a). The application to radiotherapy planning was proposed by Alderliesten et al (2013), by computing the large deformation between prone pre-operative and supine planning scans.…”

Breast radiology encompasses the full range of imaging modalities from routine imaging via x-ray mammography, magnetic resonance imaging and ultrasound (both two- and three-dimensional), to more recent technologies such as digital breast tomosynthesis, and dedicated breast imaging systems for positron emission mammography and ultrasound tomography. In addition new and experimental modalities, such as Photoacoustics, Near Infrared Spectroscopy and Electrical Impedance Tomography etc, are emerging. The breast is a highly deformable structure however, and this greatly complicates visual comparison of imaging modalities for the purposes of breast screening, cancer diagnosis (including image guided biopsy), tumour staging, treatment monitoring, surgical planning and simulation of the effects of surgery and wound healing etc. Due primarily to the challenges posed by these gross, non-rigid deformations, development of automated methods which enable registration, and hence fusion, of information within and across breast imaging modalities, and between the images and the physical space of the breast during interventions, remains an active research field which has yet to translate suitable methods into clinical practice. This review describes current research in the field of breast biomechanical modelling and identifies relevant publications where the resulting models have been incorporated into breast image registration and simulation algorithms. Despite these developments there remain a number of issues that limit clinical application of biomechanical modelling. These include the accuracy of constitutive modelling, implementation of representative boundary conditions, failure to meet clinically acceptable levels of computational cost, challenges associated with automating patient-specific model generation (i.e. robust image segmentation and mesh generation) and the complexity of applying biomechanical modelling methods in routine clinical practice.

“…For example, several methods in Refs. [13][14][15] introduce the brightness shift term in the optical flow equation to account for the dynamic intensity changes. Besides, an iterative optimization algorithm has also been presented in Ref.…”
