1. Quantification Methods for Clinical Studies in Nuclear Medicine - Applications in AMS, PET/CT and SPECT/CT
Abstract : An essential part of the development of new radiopharmaceuticals for use in diagnostic nuclear medicine is the determination of its biokinetic properties. The uptake and turn-over of the radiopharmaceutical in the source organs is of great interest since this could determine whether the radiopharmaceutical would be suitable for clinical use or not.

2. Image Processing for Quantitative Scintillation-Camera Imaging. Application to Radionuclide Therapy
Abstract : Individual-based determinations of the absorbed dose in radionuclide therapy largely rely on absolute measurement of the activity distribution and its redistribution over time. Scintillation-camera imaging is the most commonly employed measuring technique, applied in planar or SPECT mode, sometimes in combination with structural images from CT. READ MORE

3. Quantification of 4D Left Ventricular Blood Flow in Health and Disease
Abstract : The main function of the heart is to pump blood throughout the cardiovascular system by generating pressure differences created through volume changes. Although the main purpose of the heart and vessels is to lead the flowing blood throughout the body, clinical assessments of cardiac function are usually based on morphology, approximating the flow features by viewing the motion of the myocardium and vessels.

4. Uncertainty Quantification and Numerical Methods for Conservation Laws
Abstract : Conservation laws with uncertain initial and boundary conditions are approximated using a generalized polynomial chaos expansion approach where the solution is represented as a generalized Fourier series of stochastic basis functions, e.g. orthogonal polynomials or wavelets. READ MORE

5. Assessment of attenuation correction methods for quantitative neuro-PET/MR
Abstract : Hybrid PET/magnetic resonance (MR) can provide physiological, functional, and structural information simultaneously, facilitating research in neurological disorders. For quantitative PET, correction for photon attenuation (AC) is necessary. READ MORE
