1. 16. Feasibility of Dynamic SPECT-Renography with Automated Evaluation Using a Deep Neural Network

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Viktor Rogowski; [2021]
   Keywords : Medicine and Health Sciences;

   Abstract : Introduction: Renography is a standard diagnostic examination that evaluates renal function, renal pelvic dilatation and urinary obstruction. Renography is performed by injecting a radiopharmaceutical (predominately 99mTc-MAG3) and using gamma camera to image the biodistribution in a dynamic sequence. READ MORE

3. 17. Exploring Deep Learning Frameworks for Multiclass Segmentation of 4D Cardiac Computed Tomography

   University essay from Linköpings universitet/Institutionen för hälsa, medicin och vård

   Author : Norman Janurberg; Christian Luksitch; [2021]
   Keywords : Computed Tomography; Multiclass Segmentation; Image Segmentation; 4D; Deep Learning; MONAI; Unet; Cropping network; Multiaxis Segmentation;

   Abstract : By combining computed tomography data with computational fluid dynamics, the cardiac hemodynamics of a patient can be assessed for diagnosis and treatment of cardiac disease. The advantage of computed tomography over other medical imaging modalities is its capability of producing detailed high resolution images containing geometric measurements relevant to the simulation of cardiac blood flow.
