1. Cytokine capture with beads in cytotoxicity assays in microwells
University essay from KTH/Tillämpad fysikAbstract : Cytokines are small, secreted proteins that are important for cell signalling in theimmune system. Interferon gamma (IFN-γ) is one of the most potent cytokines thatnatural killer (NK) cells of the innate immune system secrete with both antiviral,antibacterial, and antitumoral activity. READ MORE

2. Activity quantification of 177Lu using a 360◦ CZT gamma camera - comparison with a dual-head Anger camera
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : 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. Evaluation of whole-body bone scans performed using a gamma camera with Cadmium Zinc Telluride detector
University essay fromAbstract : 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

5. Verification measurements on MRI-linac with PTW BEAMSCAN MR
University essay from Umeå universitet/Institutionen för fysikAbstract : In radiotherapy the main goal is to kill cancer cells, prevent them from growing and reproducing, while healthy tissue is spared. One technique to treat cancer is to use external radiotherapy where a linear accelerator (linac) is used to generate a high energy radiation photon beam. READ MORE
