About the Physicists
Each RPI physicist is certified by the American Board of Radiology (ABR) or by the American Board of Medical Physics (ABMP) and is recognized by the American College of Radiology and individual state agencies as qualified to perform radiological physics services.
Dr. Settles earned a CAMPEP accredited Doctor Of Medical Physics (DMP) degree at University of Texas Health Science Center at San Antonio (UTHSCSA) and an M.S. degree in Radiological Sciences, also from UTHSCSA. He joined RPI Radiological Physics, LLC in 2018. He is authorized to perform as a diagnostic radiological physicist, medical health physicist and nuclear medicine physicist in the state of Texas. He has successfully passed state audits and meets the requirements of Texas Administrative Code Title 25, the Texas Medical Board and the Texas State Department of Human Service. He has been trained in all modalities after completing two years of clinical residency in a UTHSCSA radiology clinic. Dr. Settles ABR certification will be complete by June 2018 after the Part 3 oral exams.
Dr. Settles has extensive knowledge of MRI systems and MR Spectroscopy and two patents pending in the US Patent and Trademark Office.
Mr. Winston received a B.S. in Physics from New Mexico State University and an M.S. degree in Physics from the University of Texas at El Paso. He participated in medical physics training courses at the M.D. Anderson Cancer Center while employed at the El Paso Cancer Treatment Center. He formed RPI in 1982 and became an independent contractor providing radiological physics services to regional and metropolitan medical centers and clinics throughout the southwest. He serves as the Chief of Medical Physics for the El Paso Cancer Treatment Center. He is board certified by the American Board of Radiology in Diagnostic and Therapeutic Radiological Physics. He is licensed in Texas for Diagnostic, Therapeutic, Medical Nuclear and Medical Health Physics. He holds a New Mexico Certificate of Registration as a Qualified Expert in Diagnostic and Therapeutic Medical Physics, as well as a New Mexico Certificate of Registration for calibrating radiation machines. He is an active member of the American College of Radiology (ACR) and the American Association of Physicists in Medicine (AAPM). He currently serves as Chairman of the US Oncology physics advisory committee (PAC) to help promote the advancement of excellence in medical physics.
Dr. Parks received a B.S. in Chemistry from Eastern New Mexico University, Portales, New Mexico and a Ph.D. in Physical and Nuclear Chemistry from the University of Nebraska, Lincoln. He joined Radiological Physics, Inc. in 1999 while still performing duties as an adjunct professor of Civil Engineering (Environmental Radioactivity and Waste Remediation Program) at the University of Texas at El Paso. He designed a Health Physics Program for the University and is still actively involved in the Air Quality and Air Pollution Laboratory. He is an emeritus research faculty member for the Institute for Toxicology and Environmental Health Research at the University of California, Davis (1993-present).
Dr. Parks is certified by the American Board of Radiology in Diagnostic Radiological Physics and holds a Texas license in Diagnostic Radiological Physics. He holds Certificates of Registration in New Mexico in Diagnostic Medical Physics and Radiation Safety Training in the Healing Arts.
Dr. Parks is the author or co-author of approximately 50 peer reviewed publications, and various limited distribution agency reports addressing the biological effects or therapeutic applications of ionizing radiation in bone and marrow, or radiation exposure and dosages. They have appeared primarily in:
- Radiation Research (Radiation Research Society),
- Health Physics; The Radiation Safety Journal (Health Physics Society),
- Science Magazine (American Association for the Advancement of Science),
- Nature (Nature Publishing Group),
- Journal of Anatomy (Anatomical Society of Great Britain and Ireland), and
- Blood (The American Society of Hematology).
Dr. Parks is an active member in the American Association of Physicists in Medicine (AAPM) and the Health Physics Society (HPS).
