The development of hybrid PET/MRI imaging systems needs to be paralleled with the development of a hybrid intrinsic PET/MRI probes. The aim of this work was to develop and validate a novel radio-superparamagnetic nanoparticle (r-SPNP) for hybrid PET/MRI imaging. This was achieved with the synthesis of superparamagnetic iron oxide nanoparticles (SPIONs) that intrinsically incorporated 59Fe and manganese iron oxide nanoparticles (MIONs) that intrinsically incorporated 52Mn. Both [59Fe]-SPIONs and [52Mn]-MIONs were produced through thermal decomposition synthesis. The physiochemical characteristi

Streszczenie:

Neurocognitive models of speech comprehension generally outline either the spatial or temporal organisation of speech processing and rarely consider combining the two to provide a more complete model. Simultaneous EEG-fMRI recordings have the potential to link these domains, due to the complementary high spatial (fMRI) and temporal (EEG) sensitivities. Although the neural basis of speech comprehension has been investigated intensively during the past few decades there are still some important outstanding questions. For instance, there is considerable evidence from neuropsychology and other con

Registration of medical imaging is essential for aligning in time and space different modalities and hence consolidating their strengths for enhanced diagnosis and for the effective planning of treatment or therapeutic interventions. The primary objective of this study is to develop an integrated registration method that is effective for registering both brain and whole-body images.

The current 'gold standard method' of detecting cancer relies on microscopic examination by specialised pathologists. However, there are risks associated with surgery and biopsies and so the ability to diagnose cancer and other diseases in a non-invasive manner is highly attractive. There are many imaging techniques suitable for this, each with their own advantages and disadvantages, which can be improved by the use of contrast agents. The incorporation of targeting vectors allows for the specific imaging of desired tissues. Further to this, the incorporation of more than one contrast agent in

Background Visual hallucinations (VH) are an important non-motor complication of Parkinson’s disease (PD) which carries a negative prognosis, but their biological basis is unclear.

Methods To assess cerebral microstructure and resting functional activities in patients with idiopathic PD and VH, I compared PD patients with VH (PDVH) and PD patients without VH (PDnonVH), while healthy controls (HC) were also recruited for comparison.

Myocardial ischaemia causes progressive cellular injury. Initially there is loss of function, followed by formation of oedema. Ischemia, if prolonged, will eventually lead to cell death. Revascularisation of occluded coronary arteries is an efficient tool to reduce infarct size in acute myocardial infarction. However, reperfusion in itself can be associated with a significant amount of myocardial damage. The structural and metabolic changes occurring in myocardial ischemia and reperfusion can now be studied in-vivo using magnetic resonance imaging (MRI) and are targets to optimise the treatmen

Deep Learning techniques are widely used across various medical imaging applications. However, they are often fine-tuned for a specific modality and are not generalizable when it comes to new modalities or datasets. One of the main reasons for this is large data variations for e.g., the dynamic range of intensity values is large across multi-modal images. The goal of the project is to develop a method to address multi-modal learning that aims at segmenting liver from Computed Tomography (CT) images and abdominal organs from Magnetic Resonance (MR) images using deep learning techniques.

This advancement can be reached through the use of multimodal tracers and nanotechnology-based solutions allowing the simultaneous delivery of different diagnostic compounds and their safe administration for multimodal imaging acquisitio

In the brain mapping case, the geodesic closest points are used as the anatomical constraints for the inter-subject non-rigid registration. The method uses the anatomical constraint in the non-rigid registration which is much more reasonable for the anatomical correspondence. The registration result shows significant improvement comparing with the iterative closest points based method.<br>In the third application, we use the non-rigid registration method to register the different sweeps of freehand ultrasound images. We setup a 3D freehand ultrasound imaging system to capture images of a human

Streszczenie:

Photoacoustic tomography (PAT) is a scalable imaging modality having huge potential for imaging biological samples at very high depth to resolution ratio, thereby playing pivotal role in the areas of neuroscience, cardiovascular research, tumor biology and evolution research. The crucial step in PAT is the image reconstruction or the solving the inverse problem. The reconstruction can be performed by using analytical and model-based methods. The reconstruction schemes like backprojection, filtered backprojection, time reversal, delay and sum, or Fourier-based inversion have shown potenti

Streszczenie:

Diffuse optical tomography uses near infrared (NIR) light as the probing media to recover the distributions of tissue optical properties. It has a potential to become an adjunct imaging modality for breast and brain imaging, that is capable of providing functional information of the tissue under investigation. As NIR light propagation in the tissue is dominated by scattering, the image reconstruction problem (inverse problem) tends to be non-linear and ill-posed, requiring usage of advanced computational methods to compensate this. Traditional image reconstruction methods in diffuse optical to
