Jorgen Arendt Jensen
Visiting Professor, Radiology - Rad/Molecular Imaging Program at Stanford
BioI am a professor of Biomedical Signal Processing at the Department of Health Technology (DTU Health), Technical University of Denmark (www.dtu.dk). My main interests are the application of digital signal processing to medical ultrasound, especially synthetic aperture imaging, vector flow imaging, super-resolution, GPU-based beamforming and implementation, and ultrasound simulation.
I received the M.Sc. in electrical engineering in 1985, the Ph.D. in 1989 for work on deconvolution, and the Dr. Techn. degree in 1996 for my work on blood velocity estimation in the book: "Estimation of Blood Velocities Using Ultrasound, A Signal Processing Approach", which was published by Cambridge University Press in 1996. I have been a full professor at DTU since 1993, and I have been a visiting scientist at Duke University, North Carolina, Stanford University, California, and the University of Illinois at Urbana-Champaign, all in the US. I became an IEEE Fellow in 2012.
I have founded and headed the Center for Fast Ultrasound Imaging (www.cfu.dtu.dk) since 1998. Currently, I am a visiting Professor in the Department of Radiology at Stanford University, CA, USA, courtesy of Professors Katherine Ferrara and Jeremy Dahl, until August 2026. I will be working here on our super-resolution method, SURE, using the Stanford large-element arrays for the acquisition of clinical data. I am also writing a book on advanced ultrasound imaging, drawing on my 40 years in the field.

Xiaojian Kang
Affiliate, Rad/Veterans Affairs
BioDr Kang received his PhD in Physics and MS in Computer Science from Indiana University Bloomington in September of 1998. Then he joined Diagnostic Imaging Science Center at University of Washington in Seattle for postdoctoral research.
In September of 2000, he worked as an MR Physicist in the Human Cognitive Neurophysiology Laboratory in Department of Neurology at University of Californian at Davis. His tasks were to maintain and modify the sequences for MR research on a 3 T Siemens Verio scanner and a 1.5 T Philips Eclipse scanner, and develop new procedures for MR data analysis, statistics and visualization. He has published 40+ papers to introduce the innovative methods for MR data analysis, which including the local landmark method, high-resolution space method, and cortical surface projection mapping method, and automated method to detect brain abnormalities. All of the methods have been applied successfully to the MR researches in the lab.
In September of 2017, he joined as an MR Physicist in Palo Alto Veterans Institute for Research (PAVIR) at VA Palo Alto and the Adamson Brain Stimulation Lab in the Department of Neurosurgery at Stanford University.His main tasks are to participate in the research projects using GE and Siemens MR scanners funded by Department of Veterans Affairs and Department of Defense, and administration of windows and linux servers for neuroimaging studies.

Kathryn (Katie) Kapp
Postdoctoral Scholar, Radiology
Current Research and Scholarly InterestsI am interested in using mass spectrometry to study protein glycosylation, a complex post-translational modification that is known to be heavily altered in cancer and could improve early cancer detection. I am using mass spectrometry to study protein glycosylation in a variety of clinical samples and cancers, but I am particularly interested in proximal fluid samples to develop more accessible ways to obtain clinical samples to study cancer and women's health.
