Creation of brain tissue-mimicking material and multi-material gradient 3D printer for magnetic resonance elastography phantom
… resonance elastography (MRE) is a non-invasive tissue imaging method that measures shear stiffness. While MRE has many benefits, it is not currently used clinically for scanning the human brain, mainly because it has not been validated with independent mechanical property testing methods. This …

Acoustic characterisation of ultrasound contrast agents at high frequency
… intravascular, ophthalmology and superficial tissue imaging. Although research studying the acoustic response of UCAs at low diagnostic ultrasonic frequencies has been well documented, quantitative information on the acoustical properties of UCAs at high ultrasonic frequencies is limited. In …

Development of Surface Acoustic Wave Optical Coherence Elastography (SAW-OCE) for Soft Tissue Characterisation
Mechanical properties of biological soft tissues are closely related to their underlying pathological conditions. In clinical practice, they have been widely recognized as a significant indicator to assist disease diagnosis. There has been enormous technical advancement in imaging modalities such …

Subdermal Fat Determined by Ultrasound and Electrical Conductivity, and Its Relationship to Body Condition Score of Dairy Cows
… field tool for estimation of changes in body tissue reserves is time consuming and subjective. The relationship between body condition score and subdermal fat (SFAT) was determined biweekly as potential for development of a low cost, portable digital ultrasonic or conductivity sensor for BCS. …

Development of a Colonoscopy Simulator for the Evaluation of Colonoscopy Devices
… literature was reviewed and possible tissue mimicking materials were selected. The suitability of the selected materials was evaluated by testing the frictional and elastic properties of the materials and subsequently comparing the results to those of colon tissue. PVA cryogel was …

Process-Property Characterization for Multi-Material Jetting Applications
Material jetting (MJ) is an additive manufacturing (AM) process that involves the selective jetting of a liquid material into the shape of a layer and subsequent solidification, often via ultraviolet (UV) irradiation, in a layer-wise fashion. The MJ process has the potential to emerge as a robust …

Fluid Dynamic Assessments of Spiral Flow Induced by Vascular Grafts
… the grafts in different surgical configurations. Mimicking components, with appropriate acoustic properties, were chosen to minimise ultrasound beam refraction and distortion. A dual-beam two-dimensional vector Doppler technique was developed to visualise and quantify vortical structures …
