1. Virtual Cycle-accurate Hardware and Software Co-simulation Platform for Cellular IoT
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Modern embedded development flows often depend on FPGA board usage for pre-ASIC system verification. The purpose of this project is to instead explore the usage of Electronic System Level (ESL) hardware-software co-simulation through the usage of ARM SoC Designer tool to create a virtual prototype of a cellular IoT modem and thereafter compare the benefits of including such a methodology into the early development cycle.

2. Segmentation of Cone Beam CT in Stereotactic Radiosurgery
Master-uppsats, KTH/Skolan för teknik och hälsa (STH)Sammanfattning : C-arm Cone Beam CT (CBCT) systems – due to compact size, flexible geometry and low radiation exposure – inaugurated the era of on-board 3D image guidance in therapeutic and surgical procedures. Leksell Gamma Knife Icon by Elekta introduced an integrated CBCT system to determine patient position prior to surgical session, thus advancing to a paradigm shift in facilitating frameless stereotactic radiosurgeries.

3. Validation of simulation tool for C-arm X-ray systems : Source and scatter model
Master-uppsats, KTH/Skolan för teknik och hälsa (STH)Sammanfattning : Continuous improvement of image quality is one of the priorities in medical imaging. Therefore, development of a simulation tool allowing to generate realistic images would be of great value to understand better the impact of the components on the image quality metrics and to choose imaging set-ups or new design features to optimize output of existing systems and to prototype new ones and to formalize the link between objective and subjective image quality metrics.

4. Comparison of two Fluoroscopic Systems used for EVAR Procedures : an Approach to Analyze X-ray Image Quality Limited to Tube Output
Master-uppsats, KTH/Skolan för teknik och hälsa (STH)Sammanfattning : Image quality in medical x-ray imaging is dependent on the characteristics of the x-ray photons produced by the x-ray tube, the detection of the x-ray photons in the detector and the image processing. X-ray image guidance during endovascular interventions is usually performed with C-arm fluoroscopy. LÄS MER
