A Short History of Gamma Corporation

by Philip J. Manly, M.S., CHP, DABRApril 29, 2021

Gamma Corporation was founded in 1978 to provide health physics services to medical and industrial users in Hawaii. At the time of its incorporation, there were no CT machines, MRI machines, mammography machines, or ultrasound machines, only x-ray machines and fluoroscopy machines and nuclear medicine departments. The initial contracts signed by Gamma Corporation were to provide a Radiation Safety Officer for several hospitals in Honolulu, and to set up a new NRC byproduct materials license for Hawaiian Sugar Planters Association for their new facility in Aiea. 

Increase In Scope of Medical Physics Work

By the early 1990's, CT, MRI, and ultrasound modalities were added to the imaging modalities available in hospitals and imaging centers. Mammography was approved for screening studies in 1994 with the passage of the Mammography Quality Standards Act (MQSA). New Hawaii state regulations licensing medical physics services were added in 1999. The Joint Commission on Accreditation of Hospitals added standards for annual testing of imaging equipment by a qualified medical physicist.

Gamma Corporation professional staff

The new Hawaii state regulations for control of radioactive material and x-ray producing machines issued in 1999 included a requirement that medical physicists needed to be board certified to provide physics services in Hawaii. The Gamma Corporation founder, who already had certification from the American Board of Health Physics, obtained his certification from the American Board of Radiology in 1994. A second physicist was hired in 1993, who subsequently passed the examination for certification in health physics by the American Board of Health Physics and in diagnostic medical physics from the American Board of Radiology. A third physicist, with extensive experience in state regulation of radiation, was added in 2005. In April 2021, a fourth physicist, who will be eligible to take his boards in 2022, was added.

By hiring the fourth medical physicist, Gamma Corporation is ensuring that quality medical and health physics services will continue to be provided to users of imaging equipment and radiation-producing sources in the State of Hawaii and the Western Pacific region. The newly added physicist holds a doctoral degree in imaging biophysics and biomedical engineering and has a very strong background in MRI (including MR safety) and ultrasound imaging, as well as experience surveying CT, mammography, SPECT, PET, and radiographic and fluoroscopic machines. Additionally, he is very passionate about teaching medical imaging physics to health care professionals.
