ASRT Names Distinguished Author Award Winners

Jun 01, 2018

The ASRT has announced the recipients of the Radiologic Technology Distinguished Author Award in Honor of Jean I. Widger and the Radiation Therapist Distinguished Author Award in Honor of Harold Silverman, recognizing the best peer-reviewed articles published in ASRT’s scientific journals in 2017. Presented annually, the Widger and Silverman awards are chosen by members of each journal’s respective Editorial Review Board after a comprehensive review of all scholarly articles published in the journals during the previous calendar year.

Radiologic Technology Distinguished Author Award
Lauren B. Noble, Ed.D., R.T.(R), and Melissa P. Culp, M.Ed., R.T.(R)(MR), earned the Widger award for their article, “Computed Radiography Photostimulable Phosphor Plate Receptors: Effect on Grid Conversion Factors,” which was published in the November/December 2017 issue of Radiologic Technology.

Noble and Culp are assistant professors for the Division of Radiologic Science at the University of North Carolina at Chapel Hill.

Their study sought to evaluate the relationship among analog grid conversion factors when using various grid ratios. The authors conducted three experiments using a range of grid ratios to assess the effect of conversion factors on exposure indicators with a computed radiography PSP receptor. When using the analog grid conversion factors established for varying grid ratios with a PSP receptor and constant peak kilovoltage, the plate was overexposed with an exposure indicator outside the acceptable limits. Thus, they concluded that the discussion of antiscatter grids in radiologic science literature should remain in the context of receptor type and digital imaging system being used, helping technologists make appropriate decisions about the use of grids while minimizing patient radiation dose. They also noted that calibrated grid conversions based on the digital systems in use, as well as the radiologist’s image quality preference, could be created within radiology departments.

Radiation Therapist Distinguished Author Award
Terrence J. Ravine, Ph.D., M.T. (ASCP); Patricia Brewer, M.P.A., R.T.(R)(T); Sarah E. Bru, M.S., M.T.(ASCP); and Shannon Tyler, M.D., earned the Silverman award for their article, “Attachment Potential and Survival of Bacterial Pathogens on Radiation Therapy Thermoplastic Immobilization Forms,” which was published in the fall 2017 issue of Radiation Therapist.

The award recipients work for the University of South Alabama in Mobile. Ravine is an associate professor in biomedical sciences and the biosafety officer for the Pat Capps Covey College of Allied Health Professions at the university. Brewer is the radiation therapy program director. Bru is a retired instructor in biomedical sciences. Tyler is an assistant professor of medicine in the division of infectious diseases, department of internal medicine, and the medical director of the department of physician assistant studies, Pat Capps Covey College.

The authors inoculated heat-treated masks with a known number of single bacterial species to determine the attachment and growth potential of pathogens linked to hospital-acquired infections to various thermoplastic immobilization forms. They sampled the masks at designated intervals to count bacterial colonies to determine initial attachment and survival capability. They also surveyed radiation therapy clinics regarding current mask storage and usage conditions. After careful analysis, they concluded that the tested bacteria do not readily attach to or survive long on the forms used in this study. The composition of the mask material, when combined with low humidity and room temperature storage, suggest a reduced risk to radiation therapy patients for acquiring an infection with these particular bacteria during intermediate to long-term therapy. However, they cautioned that it does not suggest a complete elimination of microbe transmission from improper handling of stored forms, thus, recommending health care personnel still exercise care.

The Widger award is named after longtime Radiologic Technology editor Jean I. Widger. The Silverman award is named in honor of radiation therapist Harold Silverman, an advocate for accreditation of radiation therapy educational programs.

The ASRT will honor the recipients on June 22 at the ASRT Annual Governance and House of Delegates Meeting in Las Vegas, Nevada.
