  1. 1. COMPARISON OF MULTI-CRITERIA OPTIMIZATION IN TWO DIFFERENT TREATMENT PLANNING SYSTEMS

    University essay from

    Author : Anna Lindström; [2021-05-10]
    Keywords : Medical physics; Multi-criteria optimization; Pareto front; volumetric modulated arc therapy; head and neck cancer; prostate cancer;

    Abstract : Purpose: The purpose with this study was to compare multi-criteria optimization (MCO) for volumetric modulated arc therapy (VMAT) treatment plans in two different treatment planning systems. Theory: When performing treatment planning prior to radiation therapy it is important to prioritize between absorbed dose to target and absorbed dose to organs at risk (OAR). READ MORE

  2. 2. DEFORMABLE IMAGE REGISTRATION OF SPINE MAGNETIC RESONANCE IMAGES WITH ELASTIX FOR DETAILED CHARACTERIZATION OF DISC LOADING BEHAVIORS

    University essay from

    Author : Zainab Sirat; [2021-05-10]
    Keywords : Medical physics; Registration; MRI; Spine;

    Abstract : Purpose: This work aimed to develop an optimized strategy for registration of spine magnetic resonance (MR) images acquired with and without spinal loading, as well as evaluate the quality of the registration strategy with commonly used quality assessment methods. Method: Previously collected MR images of the lumbar spine of 37 individuals were re analyzed. READ MORE

  3. 3. APOPTOTIC EFFECTS IN RENAL CORTEX AFTER TREATMENT WITH 177LU-OCTREOTATE

    University essay from

    Author : Michelle Andersson; [2021-05-10]
    Keywords : Medical physics; 177Lu-octreotate; renal cortex; kidney; QPCR; gene expression; transcriptional regulation; apoptosis;

    Abstract : Purpose: The purpose of this project was to investigate gene regulation of a predeterminedpanel of apoptotic genes in murine renal cortex after treatment with 177Lu-octreotate after one day and seven days. Theory: The kidneys and bone marrow are the risk organs in 177Lu-octreotate treatment, but by fractioning the treatment the bone marrow recovers. READ MORE

  4. 4. Investigation of high performance configurations on the Evolved Packet Gateway

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Georgios Chatziadam; Tsigabu Mebrahtu Birhanu; [2021-04-21]
    Keywords : NUMA; EPG; Computer Science; Engineering; Project; Thesis;

    Abstract : Modern servers today are based on multi-socket motherboards to increase their powerand performance figures. These setups provide CPU interconnection through a highspeed bus. If processes on one CPU need access to memory or devices local to anotherCPU, they need to traverse this bus and this adds a delay to the execution time. READ MORE

  5. 5. Design and analysis of pre-clinical experiments using a method combining multiple comparisons and modeling techniques for dose-response studies
