About Xiang Li, PhD

Xiang Li, PhD, is a staff physicist in the Imaging Institute at Cleveland Clinic. She is certified by the American Board of Radiology (ABR) in diagnostic medical physics.

Dr. Li provides clinical physics support for radiography and CT, including performance evaluation surveys, radiation barrier surveys, structural shielding designs, patient and fetal radiation dose estimation, protocol optimization, and image quality troubleshooting. In addition, she serves as the Certified Radiation Expert and the Individual Responsible for Radiation Protection for three Cleveland Clinic rehabilitation hospitals.

With an extensive research background in CT dosimetry, Dr. Li has authored and co-authored 25 peer-reviewed articles and 49 professional meeting presentations.  Motivated by her clinical work in radiography, Dr. Li has also devoted substantial effort to technique optimization and practice standardization in digital radiography, particularly for pediatric patients.

Dr. Li is an avid medical physics educator. Between 2013 and 2015, she was an assistant professor and program co-director in the medical physics graduate program at Cleveland State University. In this position, she taught radiation safety and radiation biology courses and derived great satisfaction from helping her students grow and succeed. Since joining the Cleveland Clinic in 2015, she has played a leading role in the development and accreditation of a residency program in diagnostic medical physics. In addition to serving as an associate program director and the primary rotation mentor for general radiography, Dr. Li teaches didactic lectures and hands-on labs to physician residents and fellows.

As a member of the American Association of Physicists in Medicine (AAPM), Dr. Li serves on the AAPM Committees for the Medical Physics Education of Physicians and Allied Health Professionals. She is also a member of the CT examination committee for the American Registry of Radiologic Technologists (ARRT).

Industry Relationships

Industry Relationships

Cleveland Clinic physicians and scientists may collaborate with the pharmaceutical or medical device industries to help develop medical breakthroughs or provide medical expertise or education. Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry. As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.

To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.

As of 7/29/2023, Dr. Li has reported no financial relationship with industry that is applicable to this listing. In general, patients should feel free to contact their doctor about any of the relationships and how the relationships are overseen by Cleveland Clinic.

Public Health Service-Reportable Financial Conflicts of Interest. Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients. Interactions with industry are essential to bringing the researchers' discoveries to the public, but can present the potential for conflicts of interest related to their research activities. Click here to view a listing of instances where Cleveland Clinic has identified a Public Health Service (PHS)-Reportable Financial Conflict of Interest and has put measures in place to ensure that, to the extent possible, the design, conduct and reporting of the research is free from bias.

* Cleveland Clinic physicians and scientists subscribe to the guidance presented in the PhRMA Code on Interactions with Healthcare Professionals and the AdvaMed Code of Ethics on Interactions with Health Care Professionals. As such, gifts of substantial value are generally prohibited.
