1. Feasibility of single time point dosimetry during 177Lu-PSMA-617 treatments of prostate cancer
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Introduction: Standard dosimetry methods for radionuclide therapies re- quire imaging at multiple time points post injection. An alternative method has been presented in the literature that uses previously acquired pharma- cokinetic data to create so-called dose factors. READ MORE

2. Evaluation of internal dosimetry for 225- Ac using one single measurement based on 111-In imaging
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Background and aim: There is a high interest in determining the absorbed dose in tumors and organs for various radiotherapy cancer treatments. Due to limitations in today's methods of determining the patient specific absorbed dose it is usually not proceeded clinically. READ MORE

3. On the usage of a photon counting CT detector for SPECT
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : This work explores the possibility of using a photon counting silicon detector developedfor Computer Tomography (CT) in Single Photon Emission Computed Tomography(SPECT) applications. This would allow for a more versatile and a much cheapersystem. The main focus is on determining the efficiency and resolution of such a system. READ MORE

4. High Accuracy Relative Luminescence Quantum Yield Measurements of Upconverting Nanoparticles
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/AtomfysikAbstract : The name Upconverting nanoparticles refers to a novel category of luminescence emitters that are capable of generating visible luminescence upon excitation with noncoherent and longer wavelength monochromatic near-infrared light, at excitation fluence rates as low as 1-103 W/cm2. This unique optical behaviour is of great interest to researchers as it could potentially allow for virtually autofluorescence free luminescence imaging of living tissue. READ MORE
