The SARD variety of multifractality of ventricular epicardial map** during ischemia

We have analyzed cardiac ischemia-reperfusion in an animal model using epicardial electropotential map**. We investigated the relationship between ischemia and variability of multifractality in epicardial el...

The Breast Biomechanics Reference State for Multi-modal Image Analysis

Multi-modality imaging of the breast is becoming increasingly common, and yet combining the information from the different images is difficult due to differences in the basic imaging physics, geometry, and the...

Interactive Cardiac Image Analysis for Biventricular Function of the Human Heart

We developed an interactive tool for biventricular function analysis from cardiac magnetic resonance (MR) images based on the guide point modelling (GPM) approach [1]. First we built a deformable model of both...

Map** Microcalcifications Between 2D Mammograms and 3D MRI Using a Biomechanical Model of the Breast

We propose a method to localise the 3D positions of microcalcifications found in X-ray mammograms using the 3D breast modelling framework of Chung et al. [1]. The accuracy of the method was first studied using...

Investigating Heart Failure Using Ventricular Imaging and Modelling

It is well-established that ventricular hypertrophy is a transitional phase through the development of heart failure. A hypertrophic heart can remodel to compensate the loss of pump function, but it eventually...

Method for Validating Breast Compression Models Using Normalised Cross-Correlation

To diagnose and manage breast cancer, X-ray mammography, ultrasound, and magnetic resonance (MR) imaging are used to image the breasts. In this chapter, we present a method for validating finite element (FE) b...

Breast Image Registration by Combining Finite Elements and Free-Form Deformations

During breast cancer diagnosis, the breasts undergo large deformations due to gravity or compression loads. It is therefore non-trivial to recover the deformation and register medical images of the breast in d...

Effects of Fetal Head Motion on Pelvic Floor Mechanics

We have developed a modelling framework to simulate vaginal delivery using individual-specific pelvic floor geometries derived from magnetic resonance images, which could potentially be used to study the effec...

Cardiac Active Contraction Parameters Estimated from Magnetic Resonance Imaging

Impaired systolic ventricular function is common in patients diagnosed with heart failure (HF) or ischaemic heart disease. The diminished contractile performance with impaired contractility (systolic HF) can b...

Map** Breast Cancer Between Clinical X-Ray and MR Images

Characterizing a breast lesion can involve comparing X-ray and magnetic resonance (MR) images of a patient’s breast. Tracking a lesion between these imaging modalities is nontrivial because of the different ty...

A Quantitative Description of Pelvic Floor Muscle Fibre Organisation

The levator ani (LA) muscles play an important role in pelvic floor function. With the aid of computer models and mechanics simulations, the injury mechanism of LA muscles can be better understood to prevent p...

Anisotropic effects of the levator ani muscle during childbirth

Pelvic floor dysfunction and pelvic organ prolapse have been associated with damage to the levator ani (LA) muscle, but the exact mechanisms linking them remain unknown. It has been postulated that factors suc...

Estimating material parameters of a structurally based constitutive relation for skin mechanics

This paper presents a structurally based modeling framework to characterize the structure–function relation in skin tissues, based upon biaxial tensile experiments performed in vitro on porcine skin. Equi-axia...

Predicting lymphatic drainage patterns and primary tumour location in patients with breast cancer

Detailed knowledge of the lymphatic drainage of the breast is limited. Lymphoscintigraphy is a technique used during breast cancer treatment to accurately map patterns of lymphatic drainage from the primary tu...
