  1. 1. Virtual Cycle-accurate Hardware and Software Co-simulation Platform for Cellular IoT

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Marcel Tovar Rascon; Patrik Elfborg; [2017]
    Keywords : co-simulation; cycle-accurate; ESL; HLS; SystemC; SoC Designer; IoT; SoC; FPGA; embedded; Technology and Engineering;

    Abstract : 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.

  3. 2. Segmentation of Cone Beam CT in Stereotactic Radiosurgery

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Awais Ashfaq; [2016]
    Keywords : Cone Beam CT; Convolutional Neural Networks; Image Segmentation; Leksell Gamma Knife Icon; Deep Learning.; Cone Beam CT; neurala nätverk baserade på faltning; bildsegmentering; Leksell Gamma Knife Icon; Djup inlärning.;

    Abstract : 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.

  4. 3. Validation of simulation tool for C-arm X-ray systems : Source and scatter model

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Martina Jurcova; [2016]
    Keywords : Simulation; C-arm system; X-ray imaging; focal spot; scattering; image sharpness;

    Abstract : 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.

  5. 4. Comparison of two Fluoroscopic Systems used for EVAR Procedures : an Approach to Analyze X-ray Image Quality Limited to Tube Output

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Ellinor Wemmert; [2014]
    Keywords : ;

    Abstract : 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. READ MORE
