TRUE lab undergraduate student, Siqi Wang was awarded the Mentored Research Fund Award from The Office of Undergraduate Research at The University of Oklahoma. The Mentored Research Fund (MRF) is a program to cultivate and support student-mentor relationships while working on a research or creative project. The MRF is open to all University of Oklahoma Norman Campus students. Currently he is working on the development of photoacoustic microscopy imaging system.
Congratulations Danny Doan on winning the Honors Research Assistant Program (HRAP) Award
Congratulations to TRUE lab undergraduate student, Danny Doan who was awarded the Honors Research Assistant Program (HRAP)! The purpose of the program is to involve students in a faculty research project, and teach them how to develop research into a completed project. Danny Doan is a National Merit Scholar at the University of Oklahoma, pursuing a BS in Electrical Engineering. Danny is interested in the potential of subjects and projects that explore the periphery of science and engineering and is highly motivated in breaking those boundaries, especially those in electro-optics and bionics. Currently working on Photoacoustic Microscopy (PAM), he is determined to make a difference in the project.
Congratulations Pratik Samant on winning the SPIE travel scholarship Award
Pratik Samant, a Ph.D. student working in TRUE lab, has been awarded a travel scholarship by SPIE-The International Society for Optics and Photonics. This is a merit-based scholarship offered to students located anywhere in the world, evaluated on their prospect for long-term contribution that they will make to the field of optics, photonics or related fields. Congratulations, Pratik!
Congratulations Kiana Prather on winning the Honors Research Assistant Program (HRAP) Award
Congratulations to TRUE lab undergraduate student, Kiana Prather (Xuanjin Yang) who was awarded the Honors Research Assistant Program (HRAP)! HRAP provides an opportunity for students to work with professors as research assistants on specific projects. The purpose of the program is to involve students in a faculty research project, and teach them how to develop research into a completed project. Kiana is a sophomore at the University of Oklahoma majoring in biology with a minor in chemistry. She plans on going to medical school and becoming a surgeon. She will work with us in the lab in this Fall.
Oral presentation at the 2016 RSNA Annual Meeting
Our abstract “XACT: A Novel Imaging Modality for Breast in 3D” has been accepted as an oral presentation at the RSNA 102nd Scientific Assembly and Annual Meeting at Chicago, on November 27 – December 2, 2016.
We have proposed a new imaging paradigm, X-ray induced acoustic computed tomography (XACT). Applying this innovative technology to breast imaging, an X-ray exposure can generate a 3D acoustic image with high spatial resolution, which dramatically reduces the radiation dose, while still maintaining the imaging performance.
New article demonstrates the thermal safety of a nPAT system
This study, lead by PhD student Pratik Samant in TRUE lab, shows that there is no significant temperature rise in our nanoscale photoacoustic tomography (nPAT) for imaging a single living cell. nPAT uses a laser-induced acoustic pulse to generate a nanometer-scale image. The primary motivation behind this imaging technique is the imaging of biological cells in the context of diagnosis without fluorescent tagging. We believe that nPAT will open an avenue for disease diagnosis and cell biology studies at the nanometer-level.

High resolution XACT: a new imaging modality for mapping the X-ray absorption
Recently we report a high resolution XACT imaging technique on Scientific Reports (from the Nature Publishing Group) by Drs. Liangzhong Xiang and Shanshan Tang.
This new imaging modality, X-ray Induced Acoustic Tomography (XACT), takes advantages of high sensitivity to X-ray absorption and high ultrasonic resolution in a single modality. A single projection X-ray exposure is sufficient to generate acoustic signals in 3D space because the X-ray generated acoustic waves are of a spherical nature and propagate in all directions from their point of generation. We demonstrate the successful reconstruction of gold fiducial markers with a spatial resolution of about 350 μm. XACT reveals a new imaging mechanism and provides uncharted opportunities for structural determination with X-ray.
This is a collaborative effort between TRUE lab at OU and Dr. Lei Xing’s lab at Stanford Medical School.

Welcome summer students!
This summer, two new students will be working in the lab. Jered Little and Juliana France will be exploring the opportunities available to engineers in the biomedical field. Welcome all!
Research Council Funding Awarded
Prof. Xiang and Ramseyer’s project, X-ray-induced acoustic tomography for concrete, was selected for funding through The University of Oklahoma Research Council.
The Faculty Investment Program (FIP), operated by the Norman Campus Research Council, provides funding on a competitive basis to develop and expand the scholarly (i.e., research and creative) activities of Norman campus researchers, including researchers associated with Norman Campus Programs at OU-Tulsa. The FIP is designed to provide maximum flexibility in meeting faculty needs via strategic investment of funds with a high degree of expectation and accountability. Ultimately, FIP is expected to enhance the national and international reputation of the University of Oklahoma via excellence in scholarship.
Congratulations Jesse Echeverry on winning the 2016 Summer Research Fellowship
Congratulations to TRUE lab undergraduate student, Jesse Echeverry who was awarded the BS/MS Summer Research Fellowship from BME program this week! He was awarded the fellowship for his proposal titled “In Vivo Label Free Photoacoustic Microscopy for Lymphoma Cancer Study”.
The fellowship will provide money for a salary (up to $5,000) and supplies (up to $1,500) for his summer research. In addition to performing research, he will be required to attend weekly training sessions where he will present a weekly update on his research and participate in discussions on various aspects of scientific research.
