Phantom for Calibrating Cardiac Magnetic Resonance

What A perfusion phantom that simulates myocardial first-pass perfusion, allowing comparisons between different magnetic resonance techniques and validation of the results against a true gold standard. Why Myocardial ischemia, or coronary artery disease is one of the leading causes of death worldwide. Quantitative cardiac magnetic resonance...

ReDent - Inhibitor of GSK3 activity to stimulate dentine repair

Background Dental caries remains a major clinical problem and although current treatments are effective, they are “temporary repairs” rather than complete structural and functional regeneration of dentine. Despite many years of research and development into dental materials, the basic principles on which tooth restorations are based...

A method for reconstructing the 3D surface of tubular organs from endoscope shape and camera data

The Problem In colonoscopy, a camera is inserted through the colon, a long tubular organ, in order to screen the internal tissue for cancer and other medical problems. However, inspection quality varies greatly with, even under optimal conditions, on average only 81% of the colon being inspected. A key cause for this is acute bends in the colon which...

Soft growing steerable robots for intraluminal navigation

Background: As catheters are inserted intraluminally, they exercise shear forces on the anatomy walls. These forces can cause damage to sensitive lumens such as vessels, mammary ducts, renal channels, or bile ducts. Current robotic catheters do not deviate from this conventional actuation paradigm, and therefore face the same problems. The Problem...

Constant Saturation of Magnetization Transfer in clinical MR relaxometry

Background: The contrast on an MRI image is affected by many factors, but most significantly the tissue ‘relaxation’ times. Standard radiology practice is to make MR images with different contrasts to be interpreted by a radiologist. Modern quantitative MRI seeks instead to measure relaxation times to enable precision diagnosis reconstruction. The...

Active guide wire and device decoupling with parallel transmit MRI

Background: Image guided intravascular interventions are used to diagnose/treat a wide range of conditions. For cardiac applications they require devices to be inserted via a major vessel (e.g. in the groin) that are then steered through the patient’s vasculature to the heart. This may require guidewires and plastic/metal mesh catheters to...

Virtual Reality in MRI

Improving the experience of MR Imaging subjects Briefly the innovation is a patient-controlled VR system to allow the scanning subject to control by eye movements a virtual environment. There are items displayed in the virtual world which correspond to the sounds made by an MRI scanner during its operation and the feeling of the patient table going...

Novel image reconstruction technology

Background Image reconstruction arises in many fields such as medical and pre-clinical imaging (e.g. positron emission tomography (PET), single photon emission computed tomography (SPECT), magnetic resonance imaging (MRI) and computed tomography (CT)). Image reconstruction is critically important: it takes the raw data from a scanner and represents...
