1. Establishment of a deep learning algorithm for dosimetry of radiopharmaceuticals
University essay fromAbstract : 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.

4. Quantitative analysis of Cherenkov emission imaging
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : 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. READ MORE

5. A small-scale dosimetry model of the liver tissue
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : 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. READ MORE
