1. 1. Development and testing of in-house automatized spatial omics data analysis tool : NIPMAP (Niche-Phenotype Mapping)

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Raziyeh Mohseni; [2023]
   Keywords : ;

   Abstract : The functional and anatomical characteristics of cancer cells vary among patients. Additionally, therapeutic approaches display varying responses in different individuals and cancer types due to the anatomical and functional complexity of tumor. READ MORE

3. 2. Emphysema Classification via Deep Learning

   University essay from Umeå universitet/Institutionen för datavetenskap

   Author : Olov Molin; [2023]
   Keywords : Deep learning; emphysema; CNN;

   Abstract : Emphysema is an incurable lung airway disease and a hallmark of Chronic Obstructive Pulmonary Disease (COPD). In recent decades, Computed Tomography (CT) has been used as a powerful tool for the detection and quantification of different diseases, including emphysema. The use of CT comes with a potential risk: ionizing radiation. READ MORE

4. 3. Phase Unwrapping MRI Flow Measurements

   University essay from Uppsala universitet/Avdelningen Vi3

   Author : Mio Liljeblad; [2023]
   Keywords : phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

   Abstract : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. READ MORE

5. 4. High spatial resolution study of local corrosion effects on BWR-fuel cladding : Using a combined method of GEANT4 and lwrChem

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Martin Nilsson Lind; [2023]
   Keywords : fission; zircaloy; corrosion; radiolysis; radiation; BWR; Monte Carlo; GEANT4; lwrChem;

   Abstract : The core of a BWR constitutes a highly complex radiational and chemical environment. Nuclear fission is utilized to generate power and as a consequence, large quantities of ionizing radiation are produced. Gamma and beta-particles along with neutrons have the sufficient ranges to escape the fuel rods and deposit energy in the reactor coolant. READ MORE

6. 5. Exposure Monitoring and Dosimetry - Optimizing Radiation Protection in Interventional Cardiology

   University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Institutionen för strålningsvetenskaper

   Author : Amanda Pettersson; [2023]
   Keywords : Interventional cardiology; Radiation protection; Air kerma measurements; Radiation shielding; Projection angle;

   Abstract : During interventional cardiology (IC), medical staff are exposed to scattered ionizing radiation from the patient, potentially leading to various radiation-induced health effects. Therefore, shielding devices are routinely used to reduce occupational exposure during IC procedures. READ MORE
