1. 1. Establishment of a deep learning algorithm for dosimetry of radiopharmaceuticals

   University essay from

   Author : Dennis Lipnicevic; [2022-01-13]
   Keywords : Medical physics; automated segmentation; dosimetry; kidney; nuclear medicine dosimetry; deep learning; convolutional neural network;

   Abstract : 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.

3. 2. A comparison between LiF, Al2O3 and NaCl pellets for luminescence dosimetry based on clinical and laboratory measurements

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Edita Solak; [2021]
   Keywords : Medicine and Health Sciences;

   Abstract : 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. READ MORE

4. 3. NaCl pellets for improved dosimetry

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Lovisa Waldner; [2017]
   Keywords : Medicine and Health Sciences;

   Abstract : 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. READ MORE

5. 4. Quantitative analysis of Cherenkov emission imaging

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Susanna Olausson; [2012]
   Keywords : Medicine and Health Sciences;

   Abstract : 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

6. 5. A small-scale dosimetry model of the liver tissue

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Anna Stenvall; [2012]
   Keywords : Medicine and Health Sciences;

   Abstract : 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
