senior health physicist tom morgan's paper published

Kalamazoo, MI (December 2019) Senior Health Physicist Tom Morgan’s paper, titled The Radiation Safety Officer as an Advocate for Patient Safety, can be read in Vol. 118, Issue 1 of Health Physics: The Radiation Safety Journal.

The role of the radiation safety officer is to maintain radiation exposures as low as reasonably achievable. Traditionally, the focus has been on reducing or eliminating unnecessary occupational exposure to employees and ensuring exposure of visitors and members of the public is maintained below regulatory limits. Over the last three decades there has been increasing concern expressed in the medical literature on the potential risks of radiation exposure to patients undergoing diagnostic medical imaging procedures. This paper discusses the need for advocacy and processes by which the radiation safety officer can expand the focus of a medical radiation safety program to include advocacy for applying the principles and practices of maintaining exposures as low as reasonably achievable to patients.

Odyssey Radiation Safety Software

Kalamazoo, MI (October 2019) Safely track and dispose of radioactive material in your facility with the Waste Management module from Odyssey.

Users can now track the site, location, and storage of waste containers with multiple isotopes and types of waste, complete customizable waste transactions that support a variety of disposal methods, and keep a record of users responsible for using, interacting with, or disposing of the material. Cradle-to-grave tracking allows hazardous waste in a facility from its generation to disposal all in one place. In addition, the module comes with built-in decay calculations that accurately determine when the activity of a source is safe for disposal. This helpful feature eliminates the need for users to continually update waste material profiles.

To learn more about this module’s helpful features, or to schedule a live demonstration, contact sales@versantphysics.com!


Kalamazoo, MI (September 2019) Misty Liverett came to Versant Physics in 2018 after over a decade in the healthcare field as a Certified Nuclear Medicine Technologist. Her work in health physics, medical physics, and nuclear medicine technology is bridging the gap between radiation safety and patient care. #TeamVersant

Sandy Konerth & Tom Morgan to Present at 64th HPS annual meeting

Kalamazoo, MI (June 2019) The HPS 64th Annual Meeting & Exhibition is less than 2 weeks away and we are excited to have several team members presenting abstracts and leading sessions during the meeting.

Tom Morgan, Versant’s Senior Health Physicist, will be presenting his abstract The Radiation Safety Officer as an Advocate for Patient Safety. The abstract, which was accepted for publication in the Health Physics Journal, discusses how the medical RSO can work towards developing a patient safety culture through a combination of self-education, faculty and staff education, collaboration with management, training and surveys and inspections.

On Saturday, June 6th at 8:00 AM our VP of Regulatory & Training Services, Sandy Konerth, will be leading an AAHP course with Jeffrey Brunette and Christopher Martel titled So You Want to Be a Medical Radiation Safety Officer? The primary focus of the course will be examining the radiation safety and regulatory hurdle involved in the different modalities including Diagnostic Imaging, Radiation Therapy, Fluoroscopy Guided Interventions, Emerging Technologies, and changes to the Regulatory Landscape. On Tuesday, July 9th, you can also catch Sandy presenting an abstract on behalf of Artemis Shielding titled New Era of Medical Radiation Shielding: Environmentally Friendly Lead-Free Alternate for the Attenuation of X- and Gamma Rays, as well as an abstract on behalf of Actinium Pharmaceuticals titled 131I-Iomab-B Blood Sample Handling and Occupational Radiation Extremity Exposures.

In between sessions, visit booth #307 to say hello and connect with Sandy and Tom.

Dr. Darrell Fisher & Sandy Konerth ATTENDING THE SNMMI Annual Meeting

Anahiem, CA (June 2019) Dr. Darrell Fisher, Nuclear Medical Physicist and our Vice President of Training & Regulatory Services, Sandy Konerth will be representing Versant Physics at the SNMMI Annual Meeting in Anahiem from June 22-25.

Beginning June 23rd, Dr. Fisher will be presenting on “Rationale for Personalized Dosimetry in Systemic Radionuclide Therapy: Achieving Optimal Therapeutic Ratios” from 5:15pm-5:40pm. Directly following his presentation, Dr. Fisher will be presenting Professor Sören Mattsson of Sweden with the Loevinger-Berman Award. This award is given in recognition of excellence pertaining to the field of internal dosimetry as it relates to nuclear medicine through research, significant publication contributions, or advancement of the understanding of internal dosimetry in relationship to risk and therapeutic efficacy.

Finally, Dr. Fisher will wrap up the meeting as a participant in a debate on June 25th titled: “The Linear No-threshold (LNT) Dose-response Hypothesis is a Valid model for Estimating Future Cancer Risk.” His team will argue that LNT is not valid for estimating future risk from medically administered radionuclides.

Both Sandy and Dr. Fisher are looking forward to connecting with new and familiar faces at the meeting.

Jaclyn Carroll Presents: "TG-218 and its implementation into the clinic"

Kissimmee, FL (April 2019) Our Medical Physics Resident Jaclyn Carroll delivered a fantastic presentation during a four-speaker session titled “Present and Future of IMRT QA” at the 2019 AAPM Spring Clinical Meeting in Florida. Her presentation, titled “TG-218 and Its Implementation into the Clinic,” summarized the AAPM TG-218 report published in March 2018, which provided the current status and recommendations for performing patient-specific IMRT and VMAT QA. This new process is unfamiliar to many physicists and therefore its recommendations have not yet been implemented in clinics. The intent of Jaclyn’s presentation was to describe the primary recommendations the report makes as well as share the clinical experience had by her team implementing those recommendations at the Anne Arundel Medical Center.

This was Jaclyn’s second presentation as a medical physics resident with Versant Medical Physics and Radiation Safety’s CAMPEP-accredited Residency Program.
