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. FMCW mmWave Radar for Detection of Pulse, Breathing and Fall within Home Care

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Axel Trange; [2021]
   Keywords : ;

   Abstract : Countless of elderly people fall and get hurt within their homes, worldwide, every year, and as they can not always reach out for help themselves, they end up helplessly waiting for someone to notice what has occurred. Throughout this work, it is investigated if remote sensing of the mmWave FMCW radar IWR6843AOPEVM can be adopted to detect the incident of falls, and also detect the vital signs of the human subject.
