Analysis of interaction of murine 66cl4 and 67NR breast carcinomas with tumor-associated macrophages
(Master thesis, 2016)Breast cancer is the most common cancer among women in the world, and death is usually caused by metastasis. A tumor is a heterogeneous mass of different cells, and the tumor microenvironment is complex with extensive ... -
Analysis of Intra-Tumoral Macrophages and T Cells in Non-Small Cell Lung Cancer (NSCLC) Indicates a Role for Immune Checkpoint and CD200-CD200R Interactions
(Peer reviewed; Journal article, 2021)Lung cancer is the leading cause of cancer-related death worldwide, accounting for nearly one-fifth of all cancer-related deaths. Immunotherapy with immune checkpoint inhibitors has become one of the most promising approaches ... -
Analysis of Manganese Enhanced MRI of the Normal and Injured Rat Central Nervous System
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:40, Doctoral thesis, 2010)Injury or disease in the central nervous system (CNS) such as stroke or Alzheimer's disease is often irreversible, thus patients su_ering from such injuries or diseases have poor prognosis. Important factors in CNS injury ... -
Analysis of the movements of kidney stones - Analysis of the movements of kidney stones with the help of 4D ultrasound. A cooperation project between the institute of technical cybernetics at NTNU, clinic of image diagnostics and urologic department at St. Olav’s hospital.
(Master thesis, 2015)Objective: The main purpose of this pilot study was to gather information on the movements of kidney stones in a 4 dimensional (4D) perspective through a respiratory cycle, making time the first dimension and space the ... -
Andelen posisjoneringsfeil i røntgenbilder - en baseline for Bevissthetskampanjen 2019 ved St. Olavs Hospital.
(Bachelor thesis, 2019)Hensikten med studien: Hensikten med dette bachelorprosjektet var å se på hvor stor andel røntgenbilder tatt på St. Olavs Hospital (Øya) som inneholdt posisjoneringsfeil, samt hvor mange anatomiske bildekriterier som ble ... -
Angiogenesis and radiological tumor growth in patients with glioblastoma
(Journal article; Peer reviewed, 2018)Background The preoperative growth of human glioblastomas (GBMs) has been shown to vary among patients. In animal studies, angiogenesis has been linked to hypoxia and faster growth of GBM, however, its relation to the ... -
Animal study assessing safety of an acoustic coupling fluid that holds the potential to avoid surgically induced artifacts in 3D ultrasound guided operations
(Journal article; Peer reviewed, 2014)Background Use of ultrasound in brain tumor surgery is common. The difference in attenuation between brain and isotonic saline may cause artifacts that degrade the ultrasound images, potentially affecting resection grades ... -
Annotation Web - An open-source web-based annotation tool for ultrasound images
(Peer reviewed; Journal article, 2021)The use of deep learning and other machine learning techniques requires large amounts of annotated image data. There exist several tools to annotate images, however to our knowledge there are no tools made specifically for ... -
