1. 1. Activity quantification of 177Lu using a 360◦ CZT gamma camera - comparison with a dual-head Anger camera

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Albin Lindvall; [2023]
   Keywords : Medicine and Health Sciences;

   Abstract : Background and Aim: New SPECT cameras that use CZT detectors in a 360◦ configuration has recently been introduced. Together with Bayesian reconstruction methods employing Median Root Prior (MRP) and Relative Difference Prior (RDP), this constitutes an alternative to Anger-based SPECT for activity quantification.

3. 2. Evaluation of whole-body bone scans performed using a gamma camera with Cadmium Zinc Telluride detector

   University essay from

   Author : Victor Asp; [2022-01-13]
   Keywords : Medical physics; whole-body bone scans; gamma camera; Cadmium Zinc Telluride detector;

   Abstract : The bone scan is a common nuclear medicine imaging procedure that is mainly used for evaluating several oncological patient groups. A radioactive tracer, 99mTc -labelled diphosphonate, is injected intravenously and accumulates in the skeleton. The distribution of the tracer in the body is measured with a gamma camera 3 hours post-injection. READ MORE

4. 3. Feasibility of Dynamic SPECT-Renography with Automated Evaluation Using a Deep Neural Network

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Viktor Rogowski; [2021]
   Keywords : Medicine and Health Sciences;

   Abstract : Introduction: Renography is a standard diagnostic examination that evaluates renal function, renal pelvic dilatation and urinary obstruction. Renography is performed by injecting a radiopharmaceutical (predominately 99mTc-MAG3) and using gamma camera to image the biodistribution in a dynamic sequence. READ MORE

5. 4. High-Redshift Gamma-ray Bursts as seen by SVOM/ECLAIRs

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Miguel Llamas Lanza; [2021]
   Keywords : Gamma-ray Bursts; GRBs; compact objects; high energy; ECLAIRs; SVOM; high redshift; T90; detection biases;

   Abstract : Gamma Ray Burst (GRB) are very bright cosmological explosions signalling the catastrophic formation of a black hole. Therefore, they act like real light beacons that could be detected through-out the Universe and be used as probes to study the contents and phases of the early Universe. However, only a handful sample is known so far. READ MORE

6. 5. Development of an MRI-compatible Multi-compartment Phantom for Dynamic Studies

   University essay from KTH/Medicinteknik och hälsosystem

   Author : Jonas Ström Seez; Frederick Holmer Fann; [2020]
   Keywords : Dynamic studies; Dynamic phantom; Multi-compartment analysis; MRI compatible; PET; SPECT; Gamma camera; Nuclear medicine; Dynamiska studier; Dynamisk fantom; Multi-kammar analys; MRI kompatibel; PET; SPECT; Gammakamera; Nuklearmedicin;

   Abstract : Medical imaging based on radioactive tracers exposes the patient to radiation. For this reason, a phantom is preferably used for non-clinical studies such as routine quality assurance and research. The aim of this project was to design, build and test a multi-compartment phantom to be used in dynamic SPECT/CT, PET/CT and PET/MRI studies. READ MORE
