Removing Drift from Carotid Arterial Pulse Waveforms: A Comparison of Motion Correction and High-Pass Filtering
Non-invasive methods for estimating carotid artery (CA) pressure waveforms have been recently developed as a tool to detect heart abnormalities. Among non-invasive techniques, camera-based methods have the adv...

Surface deformation tracking and modelling of soft materials
Many computer vision algorithms have been presented to track surface deformations, but few have provided a direct comparison of measurements with other stereoscopic approaches and physics-based models. We have...

Image-Based Biomechanical Modelling of Heart Failure
Effective diagnosis and treatment of cardiovascular disease is hampered by a lack of knowledge of the underlying pathophysiological mechanisms on a patient-specific basis. Biomechanical factors, such as intrin...

Quantifying Carotid Pulse Waveforms Using Subpixel Image Registration
Cardiovascular diseases are a common cause of death. Symptoms of cardiovascular disease often arise at a stage of the disease where treatments are ineffective. Hence, methods that can help early diagnosis of h...

Modelling Cardiac Tissue Growth and Remodelling
Cardiac growth and remodelling are key phenomena influencing the physiological performance of the heart and progression of various cardiac diseases. Our basic knowledge of the characteristics of cardiac growth...

Registration of Prone and Supine Breast MRI for Breast Cancer Treatment Planning
This study aimed to determine the accuracy to which prone and supine MRI can be registered using biomechanical models, to help clinicians with pre-operative breast cancer treatment planning. A framework was de...

Abusive Head Trauma: Develo** a Computational Adult Head Model to Predict Brain Deformations under Mild Accelerations
Abusive head trauma, previously termed “shaken baby syndrome”, refers to head injuries inflicted on young infants by their caregivers. There is currently a lack of scientific evidence around the causes of thes...

Subpixel Measurement of Living Skin Deformation Using Intrinsic Features
Accurate measurement of skin deformation is essential to study and understand its behaviour under mechanical load. Digital image correlation (DIC) techniques are commonly used for in-vivo subpixel measurements...

Model-based identification of motion sensor placement for tracking retraction and elongation of the tongue
Electromagnetic articulography (EMA) is designed to track facial and tongue movements. In practice, the EMA sensors for tracking the movement of the tongue’s surface are placed heuristically. No recommendation...

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...

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...
