1. Establishment of a deep learning algorithm for dosimetry of radiopharmaceuticals
Master-uppsats,Sammanfattning : Purpose: The aim of this study was to introduce a volumetric convolutional neural network for segmentation of the kidneys in SPECT images and to apply it in the dosimetry of radiopharmaceuticals of this organ, in order to decrease segmentation time and to standardize the segmentation of the kidneys. Method: Three networks were trained using two network architectures and a total of 216 retrospectively collected images from patients that underwent imaging procedures at Sahlgrenska University Hospital between 2009 and 2018.

2. A comparison between LiF, Al2O3 and NaCl pellets for luminescence dosimetry based on clinical and laboratory measurements
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Radiation protection is of importance for the general public, patients and personnel in many different situations: rare accidents involving ionizing radiation, medical examinations or work tasks in the medical clinic or nuclear industry to name a few. Optimization in radiation protection and limitation of radiation doses are essential to prevent overexposure and for reducing negative health consequences. LÄS MER
3. NaCl pellets for improved dosimetry
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : There is always a need to improve and develop new ways of estimating effective doses to people and environments that have been exposed to ionizing radiation. Dose monitoring is also important in hospitals and the nuclear industry. LÄS MER
4. Quantitative analysis of Cherenkov emission imaging
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Cherenkov emission imaging is a new optical imaging technique in nuclear medicine that takes advantage of the fact that most positron emitting radionuclides have a sufficient energy to produce Cherenkov photons. The Cherenkov photons can then be detected with sensitive CCD camera systems. LÄS MER
5. A small-scale dosimetry model of the liver tissue
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Att behandla tumörsjukdomar genom injektion av radioaktiva läkemedel är en behandlingsteknik kallad radionuklidterapi. Det radioaktiva läkemedlet består av en radioaktiv isotop, fäst på en målsökande bärarmolekyl, specifik för den vävnad vari man önskar att läkemedlet skall ansamlas. LÄS MER
