1. 1. Water-based Synthesis of Superparamagnetic X-ray Fluorescent Contrast Agents

   University essay from KTH/Tillämpad fysik

   Author : Daniel Cortés García; [2022]
   Keywords : Nanoparticles; SPIONs; XFCT; co-precipitation.; Nanopartiklar; SPIONs; XFCT; samfällning;

   Abstract : Nowadays, nanomedicine is one of the most important application areas fornanoparticles (NPs), where the design and synthesis of new hybrid nanostructures have attracted much interest, when combining properties and functionalities from different constituents. For example, they have been extensivelyused for dual-mode imaging. READ MORE

3. 2. Implementation and Evaluation of Uncertainty Estimation for Advanced Pharmacokinetic Models in DCE-MRI

   University essay from Umeå universitet/Institutionen för fysik

   Author : Jonas Höglund; [2022]
   Keywords : ;

   Abstract : The goal of this report is to develop code in Python that implements and evaluates a multivariate linear error propagation for commonly used DCE-MRI models. Two pharmoacokinetic models (PK-models) were tested; modified Kety model and two-compartment exchange model. READ MORE

4. 3. Material decomposition using a photon counting X-ray detector in low energy range

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Rasmus Solem; [2021]
   Keywords : Medicine and Health Sciences;

   Abstract : Material decomposition in X-ray imaging is used to separate different materials or elements in an image and to quantify their respective concentration. The material decomposition and quantification are made possible by the dependency of attenuation on the attenuating material and photon energy. READ MORE

5. 4. Anslagstid för diagnostiska anestesier vid frambenshälta hos häst

   University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

   Author : Isabelle Andersson; [2021]
   Keywords : hältutredning; mepivakain; diffusion; objektiv rörelseanalys;

   Abstract : Hälta hos häst orsakad av ortopediska skador är den vanligaste anledningen till uppsökande av veterinärvård i Sverige och kan vara kostsamt. Detta, tillsammans med att hälta innebär ett ökat djurlidande, ställer höga krav på veterinären att lokalisera det område som gör ont och ställa en diagnos för att framgångsrikt kunna behandla hästen.

6. 5. Graphene Quantum Dots as Fluorescent and Passivation Agents for Multimodal Bioimaging

   University essay from KTH/Tillämpad fysik

   Author : Nüzhet Inci Kilic; [2021]
   Keywords : graphene quantum dots; hybrid nanoparticles; x-ray fluorescence contrast agents; multimodal bioimaging; grafen-kvantprickar; hybrida nanopartiklarna; multimodal bioavbildning; röntgenfluorescens kontrastmedel;

   Abstract : Zero-dimensional graphene (carbon) quantum dots have been drawing attention in bio-related applications since their discovery, especially for their optical properties, chemical stability, and easily modifiable surface.  This thesis focuses on the green synthesis of nitrogen-doped graphene quantum dots (GQDs) for dual-mode bioimaging with X-ray fluorescence (XRF) and optical fluorescence.
