CURRENT POSITION

PhD Fellow

I am currently pursuing my Ph.D. program under the supervision of Professor Jørgen Arendt Jensen at the Technical University of Denmark (DTU).

SUPER RESOLUTION IMAGING

2019-2022

Ultrasound is one of the most widely used imaging modalities in modern healthcare, and it remains a field in rapid development, mainly due to the new possibilities offered by modern fast electronics, computers, and graphics processors. Ultrasound provides instantaneous images at the bedside and reveals the intricate human anatomy as well as the body’s function in terms of
movement and blood flow. So far, however, the characterization of blood flow in micrometer-sized vessels has been beyond the resolution and sensitivity of commercial ultrasound technology. As a part of a research group in DTU, I am working on development and optimization algorithms which allows us to create an image of finest vessel structures and flow information using ultrasound technology.

How to activate built-in LaTeX in Inkscape?

This experimental instructions have been tasted with Inkscape 0.91(x64) for windows
1. Install a LaTeX distribution (e.g. Miktex or Texlive)
2. Install pstoedit
3. Install Ghostscript
4. Check that you can run "latex.exe", "dvips.exe" and "pstoedit.exe" on the command prompt (cmd.exe).
   If not, add the directories where these files reside to your PATH (environment variable)
   - Note that, different values separated by semicolon without any spaces
5. Restart Inkscape. Now Latex extension should be activated (Extensions -> Render -> LaTeX...).
